Description

For riders who refuse to hang up the bike when winter hits, the Summit AmFIB® Alpha Pant is built to go deep into the coldest months with purpose-driven performance.

Our warmest mountain bike pant uses strategically mapped Polartec® Alpha® 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. AmFIB® softshell fabric wraps the legs in windproof, water-resistant protection, while a PFAS-free PI Dry® 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.

Pedal to Zero

Pedal to Zero

Pedal to Zero

We calculated the Pedal to Zero number using the EPA’s estimate that a typical passenger car produces 404 grams of CO2 per mile. For example, our Rove Short creates the equivalent of 9.8kg of CO2*. Therefore, if you ride 24 miles instead of driving, you’ve zeroed out the emissions impact of the Rove Short. This knowledge can inspire us to change our behavior. *This information was calculated by PEARL iZUMi using the Higg Product Module 2.0 at Higg.org. It includes cradle-to-gate impacts only.

PI Dry®

PI Dry Technology Infographic

PI Dry®

PI Dry® is a proprietary technology developed to enhance the performance and comfort of cycling gear. This technology provides a permanent water-shedding treatment that is applied to fabrics at the fiber level, making them resistant to saturation from rain or road spray. Unlike other treatments that can wash out over time, PI Dry® ensures that each fiber is coated with a hydrophobic treatment before the fabric is woven or knit, ensuring that the performance is built to last, not just seasonally but for the life of the garment. This feature is ideal for all-weather conditions, enabling riders to stay dry and comfortable in various climates, ultimately enhancing their riding experience and performance.

Polartec® Alpha® Direct

Polartec® Alpha® Direct is an advanced insulation technology designed for versatility and performance in outdoor apparel. This innovative material is specifically engineered to provide superior warmth and breathability, making it ideal for activities that involve fluctuating temperatures. Unlike traditional insulation, Polartec® Alpha® Direct is designed to be used without the need for a separate liner, allowing it to be in direct contact with other layers or the skin, which enhances moisture vapor transmission and reduces overall garment weight. This results in a more comfortable and adaptable garment that excels in a variety of weather conditions, making it perfect for cyclists and outdoor enthusiasts who require functional, adaptable, and lightweight apparel.
