Lightweight Stretch Crew for Trail Layering Cool mornings or shifting weather on the trail call for a mid layer that balances warmth, breathability, and sun protection. The Men's Vigor LT Crew is designed as a technical mid layer for hiking, providing just the right amount of insulation without overheating when you’re moving fast or climbing steady inclines. Whether you’re starting out before sunrise or layering up under a shell, it’s built for active days outside. The recycled polyester and elastane fabric delivers lightweight warmth with plenty of stretch for unrestricted movement. This blend wicks moisture and dries quickly, keeping you comfortable during long hikes or quick summit pushes. The streamlined fit makes it easy to layer over a base or under a jacket, while the soft feel works well for extended wear. Use it for hiking, trail running, or as a daily layer when you need adaptable comfort and mobility.
