The Mammut Skintrack SO Hooded Jacket builds 4-way-stretch Mammut FLEXGUARD Active fabric into a softshell cut for brisk, high-windchill tours. The stretch moves with every stride on a skin track without sacrificing wind protection, and harness-compatible front pockets hold climbing skins without adding bulk to a pack. A climbing-helmet-compatible hood and underarm venting round out a jacket built for setting tracks, not just surviving a storm. What Our Gearhead(R) Experts Are Saying:"The wind was cutting straight through the parking lot at the trailhead, and I never once felt it once I started moving, even reaching overhead to adjust my pack straps mid-stride. I stashed my skins in the front pockets on the descent and never missed a hardshell the whole tour."
