Core Merino 330 half -zip.
Top drawer. This item is hunt worthy as well as daily wear. Under a jacket or under another additional layer and my Hudson this, is a very comfortable weather beater. I am a fan of one merino wool. Pills a little but so what. I bought a 2X. I’m 6’4, 250. Fits a little loose like I want it.

Warmth
the half zip is warm, love the chest pocket, i just wish it had pockets for you hands. unfortunately, it is starting to pile and show wear on the shoulders and back where my backpack sits. this is only after a few wears while wearing it as layer without a jacket on top! Sita quality use to be better. it has not effected the warmth of the 1/2 zip, so i can only knock off 1 star.

What a great base layer!
What a great base layer! I wore it for over 50 days of snowboarding this season. Great at regulating temperature and kept the stink at bay after daily use between washes. Washed up nicely, I always dried mine by hanging it up and never had any problems. Thanks.

This merino half zip has been a great addition to my whitetail and duck hunting clothing system. As someone who runs hot when moving, merino has been a game changer for all my hunts. I pair a synthetic short sleeve underneath and wick moisture when sweating and stay warm when I sit still.
