The SYNC Prevail Zip Off Ski Pant uses our proprietary Dura Max 200 fabric. This fabric was built from the ground up by SYNC fabric engineers focusing on extreme durability, ventilation and waterproof breathability. Utilizing a unique technique for wrapping the yarn and weaving it based on techniques developed for automotive safety airbags, we have achieved an unsrupassed level of abrasion resistance for a technical outerwear fabric that has great stretch and is comfortable to wear with Primaloft insulation. Coupled with extraordinary dye-stuffs that rate color fastness more than 20X greater than industry standards, the SYNC Prevail Zip Off Pant will look great for years to come. The Prevail Pant is the choice for those wanting maximum ventilation, durability and a unique step-through zip off feature for easy on and off.
