Our Alpinist Stretch Pant is an extra-warm, insulated pant made for the mountain. 2-way stretch construction creates a dynamic range of motion, ensuring that the Alpinist moves with your body. To regulate your body temperature in unpredictable mountain conditions, we’ve also included Obermeyer’s CZV™ - Control Zone Ventilation technology. The Alpinist Stretch Pant features plenty of storage, with cargo, handwarmer, and seat pockets. 40 gm of needlepunch insulation keeps you warm in any conditions, making the Alpinist Stretch Pant an all-purpose, ready-for-anything outdoor solution.
