Soft, warm, and has held up over the years
Review by Melanie W. on 30 Jan 2025 review stating Soft, warm, and has held up over the years
Bought this for my partner who is very active out doors, skiing, hunting, fishing etc. Had it for a couple of years now and it has held up really well, as well as being soft and warm. No thinning or holes which i find happens with some merino items. Would buy again for sure

My second one!
Review by Trevor H. on 14 Jun 2024 review stating My second one!
My current ¼ zip Smartwool Merino is 8 years old, as is a Smartwool crewneck I wear underneath. Both have seen 8 ski seasons of -30 and +10 and have been great. No stretching, no smell...just a well-made merino.

Great quality, just have to wait for winter to wear it on the ski hill. 6’ and 175 lbs and M fits well.

Beautiful, thick and warm
Review by Trudy S. on 6 Feb 2024 review stating Beautiful, thick and warm
I was very impressed with this top. A nice thick and comfortable wool top; finely knit and not chunky. The navy colour is very nice.

Chaud, respire bien
Review by Samuel B. on 23 Jan 2024 review stating Chaud, respire bien
La taille correspond bien à la grandeur. J'ai utilisé cette couche lors d'une aventure à l'extérieur à -27 Celsius, et après de longues marches où j'ai eu chaud, j'ai pu remarquer que le tissus avait bien laissé passer l'humidité, tout en me gardant au chaud. Même si dispendieux, c'est un excellent produit, je recommande.

Very warm and comfortable. Zipper works well. Durable. Nice grey colour. I hang to dry and wash inside out in cold water to preserve.
