Men's Classic All-Season Merino Base Layer Crew

Built to work whether you're spring skiing or camped out in the middle of summer, this long-sleeve crew is Smartwool's most versatile base layer. Core Spun technology wraps lightweight Merino wool around a nylon core, so you get the durability of a synthetic blend without giving up the soft, next-to-skin comfort Merino is known for. A slim, body-following fit and flatlock seams keep it low-profile and chafe-free under a pack or shell, in any season.

Features

• Core Spun construction wraps 100% Merino wool around a recycled nylon core for added durability without sacrificing softness
• Slim fit follows the body's contours for a low-bulk layer under packs and shells
• Flatlock seam construction with offset shoulder and side seams minimizes chafing
• Side seams wrap to the front for a comfortable, consistent fit
• Lightweight 150 g/m² fabric weight suits year-round use, from cool shoulder seasons to cold-weather layering
