We've updated the fit in our year-round Merino 150 Base Layer Bottoms to improve functionality while enhancing aesthetics. Ultra-smooth Merino helps regulate body temperature, breathes well, and naturally resists odors. What else do you need in a baselayer? How about smooth flatlock seams to help minimize chafing and a wide, fabric-covered waistband? With our Core Spun technology, we've wrapped Merino around a nylon core for added durability while still keeping the comfort of ultra-soft Merino next to skin. It's everything you need and more to adventure all year long.br /> Features • Fully functional fly • Merino-lined, 1.5" (4 cm) wide elastic waistband designed for maximum comfort; 100% Merino next to skin • Flatlock seam construction designed to minimize chafing • Size Medium inseam: 31" (78.5 cm) • Material Content: 87% Merino Wool, 13% Nylon.
