Enjoy four seasons of great comfort, durability, and fit with our Men’s Classic All-Season Merino Base Layer Long Sleeve.

This year-round performer features our All-Season-weight Merino jersey fabric with a nylon core to increase durability while still keeping 100% soft Merino wool next to skin. Its shoulder and seam construction is designed to help minimize chafing while wearing a pack, and new select colorways feature a more responsible plant-based-dye technique. Gear up to go farther on every pursuit with this base layer.
