Men's Classic All-Season Merino Base Layer Crew Size:M - Energy absorber’s very compactBuilt 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.
