About this item

  • COLD WEATHER BASE LAYER. We've updated the fit of this Quarter Zip to improve functionality and aesthetics. As one of our best cold weather base layers, this garment uses Merino wool construction that keeps you comfortable and temperature-regulated.
  • SLIM FIT. Designed to meet the demands of outdoor adventuring, this slim fit quarter zip shows off a slimming silhouette while offering unrestricted movement through the arms and chest.
  • CLASSIC THERMAL MERINO. Ideal for cold-weather activities where warmth and breathability are crucial, this midweight fabric used a Merino wool construction that helps move moisture away from skin to keep you warm and dry.
  • FUNCTIONAL FEATURES. Go far, feel good with thoughtful tech to keep you trekking comfortably — flatlock seams maximize comfort while reducing chafing while increased comfort offset shoulders and side seams allow you to adventure with peace of mind.
  • GO FAR. FEEL GOOD. From wool socks to base layers for men, women and kids, we aim to provide the highest quality apparel for your outdoor adventures with a commitment to environmental sustainability, racial equity and inclusivity.


It's the little things that make up the big ones. And we really need to sweat the details to make sure that we're taking care of the big picture. To us at Smartwool, the big picture is simple to identify — defeat climate change and make sure everyone has access to the outdoors. But it's the small choices we make every day that will make sure we get there. For us, it doesn't just start with our product, but with our community and our planet. That's why all of our Merino wool products — from hiking, running, and ski / snowboard socks to base layers, mid layers, outdoor apparel and more — come with our guarantee to remain commited to enviromental sustainability, racial equity and inclusivity, plus frequent artist collabs to stay on the forefront of high quality, sustainable fashion. Once you experience our Merino wool, you'll realize that a better future is possible. Go far. Feel good.

The product itself should be fine cause I checked Smartwool's official website shows it was made in Vietnam, but the product details on Amazon still show Made in the USA, Amazon should update it in time cause label showed this product was 2022's stock.

I am 5'11" and 155 lbs. It fits really tight around torso, and it is very long. Granted it's considered a base layer, but it is uncomfortable.

Top quality and sleek fit - super comfortable, practical and warm (not too warm). Great to wear as outer layer too.
