The updated men’s Back Up Pant is built for versatility and reliable weather protection. Made from lightweight 3-layer Gore-Tex with the new ePE membrane and a moisture-wicking tricot backer, it balances weather resistance with comfort during high-output activity.
Key features include a comfortable integrated waist belt with a small internal mesh pocket. Long two-way side zippers provide easy ventilation and access to inner layers or pant pockets. A Velcro adjuster at the lower leg offers a streamlined fit when biking, while a drawcord with a soft friction stopper at the hem allows for quick adjustment—even with boots or rain gear. A button at the bottom hem keeps the cuff secure, and a subtle reflective strip along the legs enhances visibility in low-light conditions.
The Bionic™ face textile of this Gore-Tex laminate is made from 100% recycled plastic, 50% collected from the marine and coastal environments of Costa Rica.
Available in both Regular and Short leg lengths for a more tailored fit.
