The Maloja SawangM Adventure Midlayer Shirt moves from a cross-country ski trail to a bike ride to ordinary daily wear without asking for a different layer each time. A Thermopile fabric made predominantly from recycled polyester manages moisture and holds light warmth even as effort and intensity shift throughout the day. A stand-up collar with a half-length zip lets a rider or skier open up ventilation on demand, and four-way stretch keeps the fit moving through every reach and stride. What Our Gearhead® Experts Are Saying:"I drop the half-zip on the collar the second I start climbing on the bike, then zip it back up for the descent without ever feeling like I'm fighting the fabric. Later that same shirt is just what I reach for running errands, since it never reads as gear once I'm off the trail."
