Description
Built for frigid late-season sits, the heavyweight Core Merino 330 Half-Zip features our warmest-weight merino wool to keep you warm in the coldest conditions. Merino wool has an exceptional warmth-to-weight ratio to keep you warmer with less bulk and it regulates temperature through stop-and-go pursuits. Merino wool also resists odor to help minimize your scent, and our ArmorSpun merino wool outlasts traditional merino wool. And to prevent sweat from leaving you wet and cold, we added a synthetic interior that rapidly moves moisture away from your skin and through your system to keep you dry and warm.

Athelitic Cut Merino Wool is Perfect for Backcountry Adventures
Review by Gregory F. on 14 Jun 2026 review stating Athelitic Cut Merino Wool is Perfect for Backcountry Adventures
Today's elite mountaineering gear is tailored for hunters with an athletic build. I ordered the Core Merino 330 Half-Zip one size down to mazimize insulating value, save weight and pair well with my fitted Gore Windstopper shell. This is one of the best systems that I'm aware of for hunting at high elevations.

fits like a glove
Review by Leo C. on 27 Apr 2026 review stating fits like a glove
I really like the higher neck and the no hoodie .
i work outside and wear this with a heavier shirt and eliminate the jacket.
The chest pocket can be eliminated.
