Good quality, good price
Review by Andrew P. on 16 Feb 2025 review stating Good quality, good price
All good except designed more for a running back than a defensive tackle.
Sleeves and body short in XL for me @ 6', 225 lbs, other brands fit me well in XL.

250 Merino Zip baselayer top
Review by Andrew M. on 12 Feb 2025 review stating 250 Merino Zip baselayer top
Very comfortable, warm, and great value. The quality I am 188cm, 85kg. Large was the proper size for myself. The one odd thing I found was the sleeves. Most of the top is close to skin, but the sleeves are unusually loose. I have many Icebreaker tops, and all form-fitting throughout.

Thinner than expected
Review by Susie S. on 12 Feb 2025 review stating Thinner than expected
With the 250 number, thought it would have been thicker. It is still a lovely quality merino wool. Just not for the coldest winter day.

Nice weight
Review by Cameron J. on 10 Feb 2025 review stating Nice weight
This is a good quality merino base layer and a nice weight. The fit is a on the small side but fits me well. I bought the same base layer in the crew cut as well.

Surprisingly Good Base
Review by Michael K. on 6 Feb 2025 review stating Surprisingly Good Base
I ordered this figuring ‘just another base layer’. Wrong. The is a very nice fitting merino. Long body to stay tucked in; raglan sleeves so there are no seams to dig in to your shoulders; and a nice heft to keep you warm. It looks good enough on to wear as a casual T from time to time. Very nice!

Nice but a bit tight
Review by Gregory H. on 27 Jan 2025 review stating Nice but a bit tight
Seems like a well made base layer. The material is substantive and comfortable. I usually get a medium for tops, but I found this a bit too tight and thus short. Returning for a larger size.
