Merino base layer for ski days
Pull on this merino zip-neck under your ski layers for warmth without the clammy feeling reported by reviewers. Customers also note it doesn't hold odor after a day of exertion on the slopes. These points come from an analysis of customer reviews rather than direct review quotes.[1]
Everyday warmth in cold weather
As a merino base layer, this zip-neck top works for everyday cold-weather wear. Based on an analysis of customer reviews, wearers describe it as comfortable against the skin and warm without feeling bulky.[1]
Layering over a base layer
Some customers report that the roomy cut of this merino zip-neck top leaves space to fit an extra base layer underneath, making it a warmer option than crewneck versions. This is drawn from a single customer review, so fit and warmth may vary from person to person.[1]
A warm base layer for alpine skiing and winter trips
This quarter-zip merino top is made for cold-weather layering — skiers report it holds heat on the slopes without bulk, and the retailer positions it as a go-to basic for winter trips. The 250-weight merino is thicker and softer than lighter knits, with thermal resistance the retailer says is suited to extreme conditions. Customers praise its exceptional warmth-to-weight performance, making it a strong choice as a mid-layer under a shell for skiing or everyday winter wear.[1]

Comfortable, soft, warm, and stylish
This is everything I wanted from a thermal. My first time buying thermals and first purchase of Smartwool (with another two tops from Simon's). Very happy and grateful I got it on sale too. It felt expensive but I see they are quality items that will serve me well in keeping warm and avoiding odour if I sweat. Looking forward to buying more of these.
Great Design
I love this as a base layer and the design makes it wearable for a top. It's warm and comfy.
Toasty warm
this is my 2nd smartwool sweater. Nice fit and well made. I like the zipper neckline so that i don’t need to wear a scarve. I bought it on sale which is an extra bonus. Otherwise it would have been too expensive.

I really like it that it has some space for another layer inside. I have another smartwool crewneck version and this one is much warmer and comfortable than those.
