This year-round base layer is made with a Merino blend to maximize durability, perfect for four-season layering and everyday comfort.

The Classic All-Season Merino Base Layer Long Sleeve is suitable for spring skiing or summer camping. Using Core Spun technology, lightweight Merino is wrapped around a nylon core for added durability, while still keeping the comfort of ultra-soft, responsibly-sourced Merino next to skin. Wear it alone on warm days, or as a layering foundation on cooler days.

The most versatile year-round fabric features a nylon core for durability, while keeping soft 100% Merino wool next to skin. Smooth flatlock seams help minimize chafing, and offset shoulder and side seams lie smoothly beneath pack straps. No matter the season or the activity, this base layer is made for it.
