Few winter cycling jackets can boast a pedigree like Sportful's Bodyfit Pro WS Jacket, the cold weather training choice for the world beating Team Tinkoff Saxo. It was developed in conjunction with and according to feedback from the team, and if it meets their exacting standards, it'll surely offer everything you need in a winter riding jacket. Aside from the cuffs and under pocket panel, the Bodyfit consists entirely of Windstopper 4 Way Warm fabric, the stretchiest iteration of Gore's inimitable fabric and the warmest material offered by Sportful. It's a truly windproof, highly water resistant, fleece backed material that offers unparalleled breathability to keep you comfortable no matter your level of effort. Plus, it stretches four ways, making it the most elastic Windstopper fabric and providing a streamlined fit that would satisfy a pro. The inner cuff is made from ThermoDrytex Plus for maximum stretch and quality insulation, keeping the sleeves in place and the cuffs tightly sealed. The same fabric is employed under the three panel back pockets, which increases breathability without opening up the Bodyfit to drafts or the slow creep of cold. The Bodyfit Pro WS Jacket is assembled according to Sportful's BodyFit Pro construction, which means that it's designed for a snug, comfortable fit while you're in the saddle. Due to Tinkoff Saxo's input, the jacket conforms to your body with a jersey like fit that eliminates unnecessary drag and weight it checks in at a claimed 388 grams. The silicone elastic at the waist grips your body and keeps the jacket in place whether you're draped over the handlebars for dozens of base building miles or hammering out of the saddle on hill repeats.
