Under shells, over tights, the Strafe Alpha Insulator Women's Pant is a lightweight, breathable, and more versatile than you might think insulator. These are designed to add breadth and depth to your cold weather wardrobe, a trim puffy under your shell pants to provide you with protection from icy lift seats, a warmer when you need more than your cross country ski or running tights between you and winter, these extend your current backcountry wardrobe’s comfort range down into the negative digits. Introduced a few years ago in response to a request for more than just a wool baselayer to wear under a shell these Polartec® insulated pieces provide warm support to your lower body to right past your knees. With full length size zippers and open welt hand pockets these are designed with the extended functionality of being winter warmups for aerobic activities on those days when tights are not enough, or you need to stay loose before the starting gun goes off. Articulated knees enchance the 2-way stretch of the fabric so you’re not fighting fabric to move freely. Recon AIR fabric and 100% recycled Polartec® Alpha™ Insulation paired with pockets and side zips, these are an amazing addition to the active winter wardrobe.
