The Gore Bike Wear Power Trail GT AS Pant is made with a guaranteed waterproof breathable Gore Tex membrane to protect you from the worst weather that you'll encounter on a ride. To provide the utmost protection from the elements, Gore constructed the Power Trail pant with Gore Tex Active Shell. Each region has been thoughtfully considered, and because of this, the Power Trail pant is equal parts protection, comfort, and flexibility. Starting with the body of the pants, Gore used its patented Gore Tex Active Shell fabric. You know the name, but you might not know that this material is 100% wind and water proof. On top of that, it's engineered for a high breathability. That's right, with the comfort and weight of a midlayer, and the protection of a shell, this material will keep you dry from both the rain and your own sweat. And while the material is extremely malleable, Gore also pre shaped the knees to permit a full range of movement.Beyond the knees, the totality of the Power Trail pants has been pre shaped to your riding posture. And to protect the pants from you, the seat has been reinforced to resist the wear and tear of saddle abrasion. For additional coverage, the high cut back stops puddles from splashing your under layer, and the elasticized waist with a grippy insert lets you get a comfy fit regardless of your base layers' thickness. Zippers at the cuffs make it easy to get the pants on over your shoes, and Gore finished them off with reflective accents to make the ride home from the trail a little safer.And knowing that you have to get off of the trail sometime, Gore gave the pants reflective accents to heighten your visibility in low light conditions.
