Excellent product

These do run small. I had to size up to a Medium and I'm usually a small or x-small. They are super comfortable and super warm. They don't bunch up or fall down. I use them on almost every ride this time of year and I haven't gone back to last years arm warmers yet.

Arm warmers are a garment that has to be worn to be believed. Most new riders think they can't possibly do that much. Then you try them, and you feel their magic. They are amazing at keeping your body, not just your arms, warm on chilly bike rides. It's impressive how well they work. The build quality here on this is very high, and they stay up very good - an issue you'll find with cheap made ones. I tried on several pair, including other brands, and felt these run a little small. I usually fit into a medium, but with these, I needed a large. So if you're not sure, or between sizes, I recommend going one size up. Of course, try them on if you can. If you are looking for thin arm protectors (sometimes called ""UV"", or ""sleeves"") or just a layer NOT made to protect you from the cold, this isn't it. These are for cool weather.

I was worried they'd be too tight, but they are great. Real snug but still comfortable and stay up on my arms without trouble. No adjusting throughout the ride necessary. Keep me pretty warm too.

Soft, warm, and they stay put. Far better than anything I've had before. Would easily reccommend.
