Lightweight Stretch Midlayer for Trail Movement Changing conditions on the trail call for a mid layer that keeps up with your pace. The Women's Vigor LT Crew is designed as a technical mid layer for hiking, offering light warmth, easy mobility, and UPF 50+ sun protection whether you're powering up a climb or navigating shaded forest paths. It fits comfortably under a shell or packs away when the sun comes out, making it a go-to for variable weather and active use. A blend of recycled polyester and elastane delivers breathable warmth with plenty of stretch, so you can move freely over uneven ground or during quick pace changes. The fabric wicks moisture to keep you dry during exertion, while the lightweight construction prevents overheating. Designed for trail layering, this crew is equally useful for cool-weather runs, travel, or everyday wear when you need a bit of extra warmth without bulk.
