Men's Vapor Long Sleeve Crew

At a Glance Description The Men's Vapor Long Sleeve Crew is a lightweight Merino Wool layer built for 4-season performance. This long sleeve begins with natural, American-grown Merino Wool that is then spun and knit into our proprietary Vapor Wool fabric. Vapor wool combines three fibers to create a garment that is lightweight, soft, cooling, antimicrobial (odor-free), moisture-wicking and ultra-fast-drying. The Vapor Long Sleeve Crew is the perfect no-bulk solo layer or baselayer for high exertion activities. Features a slightly athletic fit. American-made with American Wool. NEW FOR 2026: The vapor collection now features an updated vortex-spun yarn construction designed for greater durability, reduced pilling, and longer-lasting performance. This improvement strengthens the fabric while preserving its ultralight breathability and soft feel that continues to improve with wear and washing. Fabric Why Duckworth Vapor Fabric?
