Men's Summit AmFIB(R) Alpha Pants

For riders who refuse to hang up the bike when winter hits, the Summit AmFIBA(R) Alpha Pant is built to go deep into the coldest months with purpose-driven performance. Our warmest mountain bike pant uses strategically mapped PolartecA(R) AlphaA(R) Direct insulation across the seat and thighs to deliver breathable warmth where it matters most-keeping you dry and thermally balanced during high-intensity efforts. AmFIBA(R) softshell fabric wraps the legs in windproof, water-resistant protection, while a PFAS-free PI DryA(R) finish ensures eco-conscious moisture management in variable conditions. Zippered Trail Access pockets secure essentials without disrupting your pedal stroke, and tapered cuffs with zip openings offer versatile fit over a range of footwear. Designed to layer comfortably over your go-to liner shorts or thermal cycling bibs, this pant unlocks cold-season trail potential with every turn of the cranks. Part of our Ride 365 philosophy, it&&';;s made for those who see winter not as a break-but as a challenge to keep going.
