Great fit and super comfortable

Loved my first one so much I bought a second in a different color. Does everything you expect from wool in a quality shirt.

Great fit soft feel

I’m 6’1” 169lbs. I have 2 of these in medium. Thumb holes are great. Would be perfect if it was 2” longer in the torso. But that hasn’t stopped me from buying it again!

Great Base/ Mid layer

Hard-wearing, great base layer. Use mostly for paragliding. I am 6'1" and 190 pounds. I ordered both a large and an XL. In T-shirts and dress shirts, I wear an XL due to my broad shoulders and lats from surfing. The Large was a bit tight and cut under my arms at first, but it relaxed and fits perfectly now with a non-binding/ non-cutting trim fit. The XL was perfect for the first few wearings, but with washing, it is now baggy and a bit stretched out in the neck. I layer the two if needing extra warmth. But if wearing a single base/mid layer, I choose and prefer the Large. I normally can not tolerate wool against my skin. These are soft and fine, but usually wear a Coolmax under in summer or a Capilene under in winter.

Merino top

Great quality and warm Do not like the length in the arms with thumb loop Just not ideal for my skiing and use with other layers Missed the loop portion when purchased, otherwise would have looked elsewhere

Second one of these shirts!

Great baselayer! This is my second shirt that I got in an XL for more casual wear. I also rock a L for those times when I want a closer to skin fit for a true baselayer up. The XL on me is perfect for lounging and as a casual stand alone. I also got the matching pants as well. Highly recommend.

Great Base Layer

Very warm and form fitting. I personally did not like the longer length of the sleeves, but it may just be a sizing issue. 5’9 150 Pounds. Got medium. Can’t wait to use it this winter.

Excellent fit and heat retention. Wicks sweat really well and is comfortable after long ours. Love the thumb hooks and that they dont compress on the space between thumb and index finger

Wore 3 times during hunting season

Wore 3x during hunting season and the material began to separate on one knee. Not a hole yet, it’s like a layer of the material is pulling apart.

Ok but wouldn’t buy again

The fit and feel could be better. I was expecting a Merino base layer to have more of a wool feel but these feel much more like a synthetic fabric however. Additionally, the fit is a bit baggy and I think base layers should be a bit more snug

Wicks moisture, arms are long enough, doesn’t stink even after days of skinning, could not ask for better
