The Alto Wool Crew is a performance midlayer built from a 60% merino wool and 40% Tencel blend, combining natural warmth and odor resistance with the moisture-wicking structure of cellulose-derived fiber. Its open-knit construction allows air to flow freely, making it effective as a thermal base under a shell or as a standalone layer across a wide range of activities. The relaxed fit and soft hand feel suit everything from ski touring to hiking to daily wear. Made from renewable, biodegradable, and recyclable materials, the garment is designed with end-of-life responsibility in mind.
