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.

I wear it all the time, but not as heavy or thick
When I read 3 layer, I was expecting something a little heavier and a thicker material. It is about as thick as my Carhartt work shirt. It's very comfortable but not the weight or warmth I was expecting to get. Even on sale I think it's $50 overpriced.

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.
