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.

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

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.

Fantastic Piece
I was looking for a comfortable merino base layer and absolutely found it in the Core Merino 330. It’s heavy enough to keep me warm and the soft lining makes it very comfortable close to skin. This has become my go-to piece when the weather turns cold. I typically wear a Large and was pleased with the fit. If you want more room, size up.
