Core Merino 220 Half-Zip Reviews

Top notch

Perfect base layer. Great fit and looks good on its own. Perfect for active wear without the funk. Wore this all bird season, zero issues.

Core 220

Looks good

Sitka merino 220 half zip

This half zip Very warm and comfortable. Only complaint is if I wear it next to skin, it causes a little itchiness. Honestly making the switch to Sitka has made my public land hunting in the VA mountains easier and more enjoyable.

Solid base layer

Love the fit, keeps you warm without the bulk. Very comfortable addition to my gear.

Great top

Love this product. Like the zipper pocket to keep from losing phone and other items.

Shirt was great and true to size

Have used this under outer

Have used this under outer layers and has worked great. Once the temp rises you can take off the outer and just use the mid layer. Would recommend.

Excellent Fit for layering

Perfect fit for what is needed from it. Purchased for additional layering in mid to late season as well as spring turkey season. Form fitted to sit over base layer without creating unnecessary bulk or bunching around the shoulders/chest.

Very comfy wool base layer!

This wool isn’t scratchy for my body. It’s very nice fitting and works great as a base layer for colder days, or just a good looking shirt for days when a long sleeve is appropriate. The fabric is substantial enough that I’m not worried about it tearing, but the 330 wool is notably thicker. I prefer this anyways as I run warm It runs true to my “Sitka size” which is a large pretty much across the board

Love it

Great quality and perfect amount of thickness

Perfect weight, did seem to

Perfect weight, did seem to steer getting fuzzy in the areas where friction occurs

Good fit

Nice fit and comfortable. The neck area can be a little aggravating is the only reason not a 5 star.

Nice addition to my wardrobe

Great feel and fit. Just what I wanted Have several pieces of Sitka and use them all Always looking for more

best under layer

I bought this for my son for skiing and he says it's his favorite base layer. It's sometimes a bit too hot for him underneath an insulated jacket here in California. He's stoked when he does wear it though.

Comfortable and warm

The most comfortable next to skin I own.

Merino 220

Core Merino 220 Half-Zip

I bought this as an extra layer for cooler and cold weather hunting and fishing. The bitterly cold weather we experienced this winter has been a true test, and it has performed remarkably well! It has helped me endure the weather and enjoy the outdoors in spite of the frigid conditions.

Core Merino 220 Half-Zip - review

Great merino half-zip. Comfortable and warm. Perfect for hunting and casual wear.

great fit

great fit and perfect as a layering piece when duck hunting.

Other great product from Sitka

Great fit, keeps me warm, well worth the cost

Sitka gear

The size was a bit too small. Do you have a double standard on sizes? A size large zip pull over should go over the cold gear under.

Core Merino 220 Half Zip

Great base layer, easy to put additional layers over it to increase warmth & block wind. Half zip allows one to cool off if you overheat & allow perspiration to escape

220 1/2 zip

Awesome have 2, I wear them abour everyday

I like it!

I was in the market for new base layers. I purchased a variety from Sitka and FL. Overall they are very similar. I think Sitka has a little better fit and more value for your money. What makes Sitka stand out is their customer service and shipping. They are superior hands down. The fact that they have tall sizes makes me a customer for life. Thank you Sitka for thinking about the tall guys.

Pretty good

Warm and serves it’s purpose.

Perfect for mid season

Perfect layer for mid season and also able to dump heat
