I bought this helmet to replace a 2020 S-Works Stratus, and I'm pretty disappointed. The (minimal) cushioning is held in place by velcro, but on mine almost 50% of the velcro anchors were unglued from the helmet when I received it. So even when brand new the foam isn't where it is supposed to be. And - even if the cushions worked as designed - they just aren't enough padding. But I can't imagine how poorly the pads would hold up when actually used for a year or so if they've failed even before customer delivery. I have an oval (not round) head, but this helmet will tighten only front-to-back and not side-to-side. And I guess my head is too round for this helmet, but it is odd that the adjustments can make it tight front-to-back but loose side-to-side. I don't think I could go down a size on the helmet and still have it fit front-to-back though. I'm going to return it because I can't keep a helmet where half of the pad mounts are unglued straight from the factory.

I agree with the several other reviews about the change in size and fit. I need an oval shape helmet and the Prevail has been my helmet of choice for several years. For some reason you changed the mold and now a medium fits too tight. I can’t wear it more than 10 minutes. I tried on a large and it’s way too big. Time to find a new helmet.

cosco muy cómodo, liviano, muy ventilado.

I used a Specialized S3 before the Prevail 3. In between, I had two more heavier helmets, which I disposed of in disgust after less than a year. My advice, don't look at the price, but at what suits you best.

So many people are complaining about the shape of the helmet being oval and not round inside. Well guess what, pretty much EVERY helmet from other brands is round inside. I have an oval head… do you know how nearly impossible it is to find a helmet for a skull not shaped like a ball? It’s the worst, I’ve been looking for a while now and when I finally tried this one on in the store, I was in love! I had the Prevail 2 previously and it worked ok, better than any others I tried. But the Prevail 3 is absolute magic on the fit. The inside top part is also rounded, like an arch. So if your head is flat on top then you won’t appreciate it, but for me, gold. I think instead of people getting upset and writing to their congressman over the new shape change, the time can be spent realizing everyone is designed differently and no helmet will fit everyone perfectly. For the rest of us that have oval heads… this helmet is the best one out there! And the ventilation is awesome! Best 300 bucks spent

Bonjour, voilà 1 semaine que j’ai eu un grave accident en descendant un col, j’ai percuté avec la tête un parapet en béton : le casque S-WORKS Prevail 3 a parfaitement résisté et m’a clairement sauvé la vie !! Je recommande à tous de ne pas lésiner sur la qualité de la seule protection que nous ayons en cas de chute…. Merci à Specialized pour la qualité de ce casque Sébastien

I love this line of helmets and this is the fifth helmet I bought and will continue to buy these!

Muy ligero y fresco

He comprado el verde por 165 €, frente a 290 € de los otros colores. Es el más seguro de Specialized y el tercero absoluto de los analizados por Universidad Tecnológica de Virginia. En cuanto a la transpiración es insuperable. Para empezar a sudar a chorros debe haber más de 32 °C, en vez de los 20 °C de otros modelos. Eso sí, si estás calvo ponte protector solar. La jaula de varillas de aramida y el nuevo sistema MIPS, son una pasada de diseño y tecnología.

When the temps are over 80 degrees, this is what I reach for when heading out. It also feels lighter and more comfortable than my S-Works Evade that I race with (on cooler days). Just remember to use sunscreen on the scalp as this helmet has a lot of exposure to the sun on top

Really like the design. Awesome ventilation.

I own a medium prevail 2. Fits like a glove. Perfect circumference for my noggin. I was hoping to invest in a white prevail 3 due to the hot Florida sun. The medium squeezes the sides of my head horribly. Immediate headache. Tried on a large and it swallows my head. So big it’s unsafe. Reddit thread says there is a round version but only available in Asian countries. No round heads or Asians in the US I guess. Do better specialized.

Eu já era apaixonada pelo Prevail 2, agora o novo capacete Prevail ganhou meu coração. É muit perceptível a ventulação que esse novo desenho proporciona, além do novo design que deixou o capacete ainda mais bonito. O prevail 3 é a minha escolha tanto para asfalto quanto para terra, amei!

Encontre una oferta inmejorable

Oval’ish shape, but fits my noggin The helmet is sleek looking, great adjustability. Lightweight Only reason for 4 stars, the inside plastic adjustment band is beginning to deform.

Das offene Design hat mir sehr gefallen. Ich schwitze viel im Sommer. Mein bequemster Helm war bisher der Chamonix vor zirka 9 Jahre. Ich musste ihn nach einem Unfall verschmeißen. Hoffentlich bin ich mit diesem Helm wieder auf dem goldenen Pfad. Persönlich gefällt mir diese Fjällräven-Grün sehr. -1 Stern wegen dem Triloc-System. Man kann den Straps unter den Ohren umständlich einstellen.

Very nice helmet

Literalmente, me ha salvado la vida y esta como si nada, es caro pero es mejor pagarlo lo prometo, acordaos de mis palabrad cuando os pase algo.

Looks gorgeous in the Hyper Dove colourway, but the redesigned fit means the new Prevail 3 NO LONGER FITS ME!!!! Very angry and very disappointing, especially considering that Specialized has made a round fit version that could potentially meet the needs of my fat Asian head, but is NOT AVAILABLE IN AUSTRALIA. This move is non-sensical. I've had the LARGE original Prevail and Prevail II and all fit well. But the elongated shape of the new design of the 3 means it puts too much pressure on my temples as the maximin sizing has been reduced from 63 to 62, which should still theoretically fit me. Be warned.

3 months after purchasing, I crashed, smashing my right side against the kerb from head to hip. The helmet was a write off and I almost became one but my head was completely fine. Replaced with another Prevail 3 under assisted replacement.

프리베일2 벤트 검은색을 사용하다가 겨울인지라 밤이 어두워져 흰 헬멧 살 겸 샀는데 살짝 더 무겁긴하나 더 시원해요. 여름이었다면 더 큰 체감을 보였으리라 생각해요.

Used to wear Specialized lids all the time before moving to Bell and then had a MET Trenta carbon... was intrigued with this design so took the plunge and got one... WOW. Fits my oval head just like I remembered Specialized and the design and workmanship is just exceptional. And it really is the coolest/most breathable helmet I've ever owned.

Very comfy

Great ventilation, good looks and for my head, a near perfect fit. A very good summertime helmet.

Loved it

I was in a serious cycling accident in mid Aug of 2023. I was wearing the S-Works Prevail helmet and according to the physicians if not for that helmet I most likely would be dead. Never skimp on a helmet and the S-Works Prevail is the best choice.

Light and comfortable, great ventilation

Excellent ventilation, looks good, and it fits perfectly to my head.

I feel the wind blowing across my bald head with this helmet.

Very nice helmet

Muito bom, leve e vetilado

Produto de primeira qualidade!!!

Lightweight and fits perfect

It fits my Asian head great on the sides and top. Ventilation is insane. My size L weighs 325g. In comparison, my Bontrager Specter with Wavecel weighs 20% more at 389g. I got the Mountain White and it’s a matte finish so I expected some smudges but it also came with a couple of scratches. Didn’t bother me enough to exchange it but I think that if you’re paying $300 for a helmet, it should come pristine and some people may be turn off by that. That’s why I’m only giving it 4 stars.

Glad I decided to try this iteration of the Prevail....many years ago (2017ish) I purchased a Prevail and was unable to get a good fit, no matter how much I cranked on the knob (way too loose...kinda like "sloppy loose"....was very disappointed) .... this Prevail-3 is a perfect ...clearly several years of "tweaking" the design has paid off. Took it out this morning for an initial 30-mile ride ... very warm and humid this morning so a perfect weather for test ride. Perfect fit, retained retention throughout the ride, exceptional ventilation and extremely light weight...sunglasses storage was easy to use and is very secure.

Weird fit. I wish the round fit option were available in the US. Medium is way too tight, but the large is insanely roomy. Seems like a cool helmet though.

I have had many S Works helmets over the years, including a Prevail 2. I could never feel comfortable with the 2, so I was hesitant to try the 3. The Prevail 3 felt great right out of the box and has proven to be the best and most comfortable helmet I have ever worn. I highly recommend the Prevail 3.

Awesome helmet, the venting is amazing, riding in warm weather I can't think of a better helmet.

Je sors d'un accident de course avec le Prevail 2, j'ai tapé fort tête en avant sur un rocher. Le casque est détruit et il m'a sauvé la vie. Je le tiens à la disposition du service Technique. Je reprends un Prevail. Merci Specialized.

After enjoying the spoils of previous Prevail models throughout the years, I have found myself disappointed with this iteration after ~1 month of use. Overall, it's a snazzy helmet. Fits a higher/smaller than the Prevail II, though I find it comfortable and aesthetically on par with what I would expect from the Prevail line. However, at the price point, I've been disappointed with two features. 1.) The Velcro on the padding is easily dislodged and seemingly misaligned by design. This has led to much sweat-induced frustration during rides, and my addition of supplemental Velcro to secure the padding further. 2.) The Angi sensor from my Prevail II does not attach. Either that, or I'm unable to figure it out with reasonable effort. The info on the Angi page leaves much to be desired. Overall, this is a snazzy helmet and I'll keep giving it a second chance. Though, for $300.00 I'd prefer to not have to.

So comfortable that I forget it’s on. Definitely cooler than other helmets I’ve tried. I was right on the line between two sizes so went with the bigger size and it adjusts perfectly! Nice fit!

Great helmet, comfortable padding and fit and great colour. A great upgrade from my Mojito. Highly recommended.

Ho acquistato questo casco a causa dei miei problemi di sudorazione e riscaldamento della testa. Mi sono trovato subito bene con la calzata e le regolazioni, da subito un ottimo approccio e massimo confort . Mi ha sbalordito la leggerezza estrema di questo prodotto, non mi accorgo nemmeno di indossarlo. Per suanto riguarda la sicurezza faccio affidamento alle specifiche tecniche molto innovative e rassicuranti ma spero di non trovarmi mai a dover recensire un’esperienza di crash. Io lo uso in gara nel cross-country e sono molto contento della mia scelta. Io uso solo prodotti a marchio s-works, dalle scarpe alla e-bike e ora anche il casco, spero che prossimamente s-works ampli sensibilmente la sua gamma di prodotti.

This is the first helmet I've tried that fits perfectly. Despite others complaining, it is a great helmet - light, not bulbous, and more or a long-oval shape. It's a huge upgrade from the various POC helmets I've had in the past.

Adquirí este casco hace 3 semanas, sufrí una caída la semana pasada, el casco se fisuró, hizo su trabajo, inmediatamente entré en contacto con el pavimento el casco se acomodó y me protegió. Lastimosamente Specialized actualizó las políticas de seguro y garantía de crash replacement que manejaba anteriormente del 50% del valor del casco. Aunque es un casco muy bueno, ventilado, liviano y muy bien diseñado desde lo estético, no deja de ser costoso, considero que para este tipo de productos S-Works se deberían mantener este tipo de beneficios. Esto obliga a considerar otra marca que si tenga este beneficio, y que al igual que este casco este en el Top del Ranking de Viginia Tech Helmet Ratings, por un costo menor o muy similar.

You can not adjust the side straps with the TriFix which is the side strap connector to the chin strap. So, if the your head is not the right size in side length, the TriFix may be hanging down to your jaw or pass it.

Great helmet

La atención y la entrega de la mercadería!! Un lujoooo, lo recomiendo al 100%

I’ve worn the previous models of this helmet for years, they’ve been great. I looked forward to the breezier update. But the thing does NOT FIT. I have to cram it on my head and it doesn’t ratchet down at all. Same size as my previous helmet. The shape is different. I’m not even going to try the next size because the shape is just way off for me. It’s not going to work for me. Super disappointed because helmets are such a big part of riding and can really make or break the experience. I’m mad I have to start the hunt over again. Why did they have to mess with it? 😞

Excelente casco, buenas terminaciones, bonito, muy liviano, buena ventilacion......

Muy buena atención, responden al toque, compren sin miedo. El casco muy bueno muy recomendable.

Exelente como todo lo tope de gama de specialized

I've ridden every version of the Prevail helmet for the past 10 years and this is superior in every way. The fit and finish is stunning. The design is modern and I feel confident wearing it. And the fit is top notch, especially the thin straps which practically disappear and make the helmet feel even lighter than it is somehow. I LOVE this helmet.

Extremely comfy in warm conditions. Fits me well, was a medium in the Prevail 2, medium in this too. Overall the quality is really really nice. VT score is a plus.

I was recently knocked off my bike (by another cyclist!) and went down heavy. My head hit the ground first and I actually heard the foam in the helmet compress when I hit the ground. Absolutely no head injuries. The helmet saved me from serious head and brain injury. Unfortunately, my hip hit the ground next and I broke by hip! But the helmet couldn't have helped that. It reinforced the need to buy a good helmet and always wear it properly with the straps all adjusted correctly. Now I'll be looking for another one...

Very comfroble light weight.

Producto Increible, se paso lo ventilado que es. Lo bueno que tiene las mejores certificaciones de seguridad. 1000% recomendado!

Had the opportunity to try on in my LBS. For my head, the fit was perfect.

Specialized es una marca de confianza en todos los aspectos , comodidad seguridad y tecnología

Material de boa qualidade. Produto premium.

Producto excelente, muuuyyy bueno!!!

Awesome helmet

EXCELENTE PRODUCTO

Beautiful helmet. Well constructed and great packaging. Truly the best ventilated helmet I've ever owned.

light and very ventilated ideal for summer

The sizing is bizarre. Maybe you used your RETUL data to optimize sizing but in doing so you messed things up for your long-time helmet users. The best thing you can do is to bring the round fit sizing on this to the U.S. They are available in Japan and other areas. If you do that then many of us will be happy — and you won't get so many product returns.

I've been wearing medium Specialized helmets since the Decibel came out in 2005. I have also had the Prevail and multiple Prevail II's in their different forms. All in medium. The Prevail III in medium is now sadly too small for me and a large is way too roomy. I really wanted to continue using Prevails. They tend to perform well in safety tests and are normally a good light fit. If this fits you well go for it.

Excellent casque. Forme, design, confort... tout est super. A la hauteur de Spé !! Le seul défaut : le prix... Mais ayant déjà eu un accident (renversé par une voiture) la tête est la première à taper le sol. Le casque est une priorité. Ne pas lésiner sur la sécurité.

Wear a medium in the Prevail 2 and barely fit in the 3. No chance of wearing a winter cap. Also the shape has changed and not as comfortable.

Really like the look and design of this helmet…but for some reason, Specialized totally changed the fit. Medium was perfect for me before but is now super duper tight. Might have to try a large. Definitely can’t fit anything on my head under the helmet. Specialized, your helmet sizing and shaping was perfect before—why did you change?!

Best helmet I’ve ever owned - light, well-ventilated, and aerodynamically efficient

Great for the summer as the helmet is super breezy. If you ride in a cold climate I would pick a different helmet like the aero helmet (or wear a warm hat) because you can really feel the cold air on your head.

Bin rundum zufrieden mit dem Helm. Bei hohen Temperaturen glänzt er mit perfekter Lüftung! Der einzige Kritikpunkt - und deshalb nicht die volle Punktzahl - ist der sehr einfache Verschluss der Helmgurte. Für ein Helm dieser Preisklasse kann man mehr erwarten. So ein Verschluss findet man eher bei Helmen im Billigsegment.

Helmet was solid and absorbed the impact. Fellow rider looked at it and said, don’t worry it did what it was suppose to.

Helmet fits true to size and is very comfortable. Helmet doesn’t move and fit nice with larger sunglasses

I've been using the Prevail since its inception. Owned and loved every version. The PV3 is a great looking helmet and the ventilation is fantastic. I've always worn a size Medium with perfect fitment. I purchased a Medium and to my disappointment, it was too narrow. Not sure if it was designed to sit higher than the PV2, but just didn't like it. I like my helmets to sit more flushed where the front edge of the helmet sits right above my eyebrows. I went ahead and exchanged it for a Large. Fits better for sure, but larger than the PV2 medium. So, I'm kind of stuck between sizes I guess. Of course, I was hoping to stay with the Medium b/c the helmet is already heavier than the PV2. So going to the Large would add even more weight. To be fair, once on and riding, don't really even notice the weight. In the end, I'll keep the PV3 b/c it looks good, offers great protection, and is comfortable on. So if you measure 57-58 cm and wore a Medium berfore with the PV2, try on the helmet first!

Improvements over Prevail 2: - Sizing: Medium was a little too big for me, now it's just right - Venting: obviously - Line of sight clearance: the brow of the helmet is higher, improving sight when in the drops or in a tuck - Retention: the helmet slips less over bumpy roads/trails The big drawback is the failure of sweat management. Perhaps this helmet was tested at pro speeds only, but with my amateur legs on a slow, steep climb, the brow pad saturates quickly and the sweat goes into my eyes. On the Prevail 2, the brow pad wasn't up to the task either, but at the very least the sweat would drip in front of my face, off my sunglasses and eyes. With the Prevail 3, it's the worst of both worlds: the pad is too thin to hold sweat, and it doesn't drip ahead of your face. One would think that a $300 helmet wouldn't require a kludge like having to wear a sweatband.

I had the previous Prevail and liked it very much. Better ventilation than the Giro owned before. The new Prevail has even better ventilation. Especially noticeable the past 3 weeks in July here in New Jersey. The issue? The internal width of the helmet is narrower. I wear a Halo headband (the standard width) and the new Prevail presses the sides of the Halo into my head, causing sore spots. Sore enough to have to loosen the ratchet adjustment mid-ride. I’ve since purchased the narrower 1” Halo and the soreness is no longer a problem for me.

Very light and well constructed helmet.

I used to be a small in the previous Prevail helmets, but had to size up to a medium now. Definitely a change in shape/size for these. The triflex attachments do sit lower below my ear than previous versions. Something to be aware off. Overall though, love the helmet due to low weight and venting!

I have been riding Giro helmets for years and liked the fit, feel, and look. I have been in the market for about a year and saw the release of the new helmets and hemmed and hawed over this or the areo version. I was glad I picked this one and have worn it now on about a dozen rides and am incredible happy with it. It is incredibly comfortable, fits well, and the ventilation is excellent. Also, I find it holds my glassed much better than any of my previous helmets with no risk of them falling out. The one issue I had was adjusting the chin strap fitting around the ears. Sounds weird, but most previous helmets have and easy adjustment to snug the strap up around the ears, but struggled with this. Regardless, great helmet!!!

It seems every helmet maker has changed their sizing/helmet shape these days (I have sent back new POC and Smith helmets this year in my quest to find a new helmet because of this). A large used to be plenty for me to wear a headband (bald guy) or a stocking hat during the winter under the helmet. The fit with a headband is tight - no room at all and squeezes my head some. I tried to put the helmet on with a thin stocking cap and it's very tight and probably won't work for the winter. Love the design, airflow, and construction (will keep the helmet for the warmer months but am not sure what I'm going to do for winter). Absolutely hate the fit. There is some fore/aft space available, but not laterally. Design seems to be more oval than round.

Looks good, probably preforms well, and is light as heck; BUT no Orange! Practically half the riders I see wear Orange helmets.

Checks all the boxes. Light, airy, safe. Best Spec yet.

Looks nice, but after years of wearing a Size Medium, this was too small and I need to size up. I don't understand why the sizing would change. I've always been at the bigger end for Med, but they fit fine - so if you are a true middle of the road Med you might be okay - if you are borderline this runs small.... had to return

디자인, 기능 등 모든면에서 압도하는거 같습니다.

The medium of older models fit me perfect, but was right on the border to needing a large. Now I definitely need the large.

Stocked with my new helmet! Heads up, it fits a little smaller than the previous version
