Core Merino 330 Half-Zip Reviews

EXCELLENT PRODUCT

Lightweight and warm.

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).

Versatile and warm

My favorite merino wool shirt! I wear this over a light layer and it works great at keeping me warm. Love it.

These have become my go

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.

Light weight but insulated

Surprisingly warm for how light this mid layer is.

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.

330 half zip

If you're looking for a heavyweight thermal this is it! Extremely warm layering option.

Great baselayer highly recommend. Waa warm even in single digits when using this and the stratus jacket

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

If you are looking for base layer warmth - this Sitka product will perform. Over time I have purchased 4 and when I’m looking at warmth for the outdoors wool is my go to choice!

Is super warm

Core merino 330 half-zip

Used in Nunavut Canada did a great job of keeping me warm &comfortable

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.

Great Base Layer

A fantastic piece to use for layering or everday wear. I specifically wanted the halfzip to avoid multiple hoods when it comes to layering for those cold hunt and couldn’t love it more.

Just right

Wore this on a late season hunt with core lightweight underneath. Kept me warm, dry, and comfortable during the temperature changes throughout the day. Impressed.

Core Merino 330

Awesome!

Awesome quality

This is another awesome quality product by Sitka gear. I’m a big fan of Sitka and own many of their products (coats, pants, hats, gaiters).

The core merino 330 is great for layering. I used it this year during muzzleloader season with my Stratus coat and thanks to the combination was able to harvest a nice buck in the snow!

Great fit

I am a tall person, with long arms and this shirt fit perfectly. I’ve worn it a few times for snowmobiling and it kept me warm, without being bulky. Can’t wait till deer season. It will keep me warm without the layers

Core Merino 330 Half-zip

Sitka quality.

Shirt

Very nice weight. True to size

Since switching the sitka a

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 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.

Core merino 330 half zip

Great product. Very warm for an under layer but nice enough to wear out to dinner. Wife approved!

Core Merino 330 Half-Zip

As always, great product. Fits well and keeps me nice and warm.

Warm

Surprisingly warm layer, recommend.
