I was not expecting this jacket to be SOOO good. Neoshell is a new technology to me. I have always been a Goretex Pro kinda guy, but wanted to give this technical garment a try. I was completely blown away by how it performed. We rode for about 2.5 hours in rain falling at a rate of roughly .4-.5" per hour, so heavy heavy rain. Temps were roughly 45 degrees F. I wore the Altered edition long sleeve trail jersey under the jacket and that is it. I was blown away that not only did I stay dry, but the jacket breathes insanely well. I had some dampness in my jersey from perspiration, but otherwise I was dry. I love Neoshell because you dont have to be so crazy with how you care for it, unlike goretex pro products. HATS OFF SPESH!!!! I am so excited to see the direction your apparel is headed!!
