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.

Epic Shirt

I have had a lot of wool over the years and this is by far my favorite, it regulates temperature sure well, the fit is great and it does not hinder movement. I was not sure that I would like it due to the zipper, the zipper is not uncomfortable and is long enough to ope the shirt up enough to dump lots of heat and come up enough to keep the heat in at your neck. I have gotten wet putting out decoys, wet dogs, getting stuff out of the water that fell in duck hunting and etc, it has kept me warm while wet

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.

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.

Everyday nonstop, essential

I wear this nearly daily, I only wash it just to feel better about the people I work with truthfully, I used it in the field for about a month before whitetail season ended and it was phenomenal compared to the hooded version, don’t feel restricted in an obnoxious hood you’re forced to wear for the garment to be comfortable. BUY THIS.

Since switching the sitka a few years ago, this product has not let me down. I’ve been warm. I’ve been dry. It’s definitely improved my hunting experience. For all the nice Sayers it say it’s overpriced and it’s not worth it. I would strongly suggest that you try it. You won’t be disappointed.

Core Merino 330 1/2 Zip

I'm 6'0, 250lb and purchased the XL. Sleeve length is great and while the torso is snug it works since it's primarily a base layer. I almost exclusively use it as a "next to skin" layer. Was purchased in hopes to keep me in the treestand longer and it does that very well. I would recommend purchasing this item.

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.

Soft and warm

I have a few different options with Sitka base layers and this is probably my softest/warmest choice. I use it more in less active situations such as ‘sits’ and prefer the Heavyweight Core for active pursuits. Extremely well made like most Sitka products and highly recommend for cold sits.

These have become my go to in any type of cold weather hunting situation. I really like the zip option for them morning that start off cold but warms up by the time the hunt is over. This is a fast way to cool down without having to take all your gear off just to remove a thermal.

Core 330

Fits good, runs true to size. Not as warm as I expected. I like the thumb holes and the quarter zip. Dont see the need for the zippered chest pocket in an underlayer. Pocket zipper gets a bit bulky when you start layering, especially when you stack 2 pieces with the same zipper. Dont get black if your gonna wear it as an outer layer. Its kind of a faded black that looks kinda shabby.

A good, heavy base layer

Its pretty heavy for a baselayer, but it will be great for late season hunts when my lighter layers just dont add quite enough warmth. I wish the sleeves were just a bit longer (i'm 6'9", 270lbs).

Good product

Used as my base layer during snowy deer season in my tree stand. I had many layers on and was sweaty after walking up 2 steep hills but was not cold after climbing up the tree with my stand. The base layer did its job and kept me warm while wicking moisture so I could stay warm
