Gore Bike Wear gave the Power Trail WS SO Thermo Jacket top shelf materials and a relatively simple design to extend your riding season well into winter. Long after your buddies have hung up their bikes for the season, The Power Trail Thermo's fleece lined Windstopper main body fabric will have you comfortably cranking out the miles. The jacket's anatomic cut is designed to drape comfortably on the bike and off, so you can wear the Power Trail jacket during your ride and at the pub for your post ride beer. Due to the effectiveness of the WindStopper membrane, Gore has included a strategically placed two front ventilation zippers with integrated zippered pockets in order to give you the ability to moderate your temperature. Perhaps the only details that give the Power Trail jacket away as a cycling piece are the two zippered pockets on the back. There's also a zippered Napoleon pocket on the left breast and small cloth for cleaning your eyewear. The tail is cut a tad longer in order to accommodate your position on the bike, and the lower hem and sleeve cuffs are bound with a wear resistant elastic band. Reflective elements on the shoulders, back, and forearms will also increase your visibility to motorists in low light conditions.
