What Our Gearhead(R) Experts Are Saying:"These are my go-to baselayer bottoms for cold-weather objectives. The vented crotch and stretch cuffs keep things comfortable and secure, while the fabric breathes well under a shell-no overheating even on the skintrack."When the mountain calls, the Summit Pant answers with comfort, breathability, and dialed-in fit. Built with VERSA(TM) fabric, this technical base layer bottom is engineered to handle hard pushes uphill and extended days in the cold. It moves with the body thanks to four-way stretch, resists odor, and wicks moisture fast to keep things dry and comfortable no matter how many layers stack on top. Designed to pair perfectly with midlayers and shells, the Summit Pant features a soft-flex waistband that sits flat under a pack or bibs. Stretch cuffs lock in warmth and stay put, while a vented crotch boosts airflow where it's needed most. With abrasion resistance and a contoured fit, this base layer is made for long days chasing summits.
