Sitka Core Merino 330 Half-Zip

Core Merino 330 Half-Zip

When cold weather settles in and lighter layers stop cutting it, the Core Merino 330 Half-Zip brings the heavyweight warmth you want without the bulk you don’t. Built for frigid late-season conditions and demanding days outdoors, this versatile layer helps you stay warm, dry, and comfortable whether you're moving hard or slowing down in the cold.

Made with the warmest-weight merino wool in the 330 Series, it delivers an exceptional warmth-to-weight ratio while naturally regulating temperature through stop-and-go activity. ArmorSpun Merino Wool adds durability beyond traditional merino, while the recycled synthetic interior improves moisture management, moves sweat away from your skin, and adds anti-itch comfort. The result is a dependable cold-weather layer that performs in the field, at camp, and anywhere winter conditions push your gear harder.
