Merino 260 Tech 1/2-Zip Top offers heavyweight warmth and breathability for winter layering
What Our Gearhead® Experts Are Saying:
"This is my go-to base layer for deep winter missions. The heavyweight merino keeps me warm on the skintrack or lift without ever feeling bulky or clammy. The offset seams and gussets are a game-changer for all-day comfort, especially when layering under a pack."
When the cold sets in and layering becomes essential, we reach for the Merino 260 Tech 1/2-Zip Top. Crafted with heavyweight 100% merino wool, this piece offers the soft, breathable warmth we need whether we’re charging through powder, snowshoeing tree-lined trails, or gearing up for a chilly alpine start. The natural temperature-regulating properties of merino keep us cozy without overheating, and it resists odor so we can keep moving day after day.
Details like gusseted underarms and offset shoulder seams help us stay comfortable under packs and outer layers, while flatlock seams prevent irritation during high-output days. The half zip design adds quick ventilation and easy layering versatility. From first tracks to winter treks, this is our foundational piece for serious cold-weather adventure.

Perfect for Fall and Spring, Winter as base layer
[This review was collected as part of a promotion.] It's beautiful, warm and functional! Had to return a Large, which I usually wear, for a Med to get a nice base layer fit.

This is my sixth Merino 260 tech long sleeve half zip therma
[This review was collected as part of a promotion.] I love this Icebreaker top ... I buy a new one every year, they stay in excellent condition year after year I wear them every single day in the fall & winter hiking in New Mexico or traveling too far off lands like New Zealand, Iceland, Norway There's nothing better for comfort and warmth whether you're wearing it during the day out having fun in the winter Wonderland or at night sleeping in your camper van

I have several of these shirts
[This review was collected as part of a promotion.] I wear this shirt or the ones I have like it in other colors almost every day except in the summer. They layer when it's cold, and are comfortable on their own in spring and fall. Because they're 100% merino they don't smell even after a week of wear. They do have to be cold water washed and hung to dry. My others are black, gray and navy, so I like having one that's more colorful, but not at all garish.

Thermal top as expected, color is off
[This review was collected as part of a promotion.] You can never go wrong with this thermal top. I own several and find them to be both functional and look good. The color on this one however is terrible. It's closer to a rust brown. I'll keep it since it was a sale item, but had I paid full price for this I would returned without a second thought.

True to size. Comfortable as a base layer or over a shirt for working out in my cool garage. I can wear it all week and let it air out between wears, good as new the next day.

Great midlayer
Got this to add to a thinner base layer on cold days. Works great! Comfortable, washes well, very soft, not itchy.

The BEST, most comfortable turtleneck.
[This review was collected as part of a promotion.] I love this product so much....I have given 4 to friends for presents and purchased one for each of my sisters. Along with that I have purchased 3 for myself which i rotate through. They are amazingly comfortable. easy to wash and look great. I play golf in them, hike in them and wear them out to dinner with a scarf at add bit of jazz. One of my all-time favorite products!

Great Product!
[This review was collected as part of a promotion.] I have had one of the 260 Long-Sleeve, quarter-zip tops for about five years and absolutely love it. (I used it on a trek to Mt. Everest base Camp.) I purchased this one for my partner, who plays "winter golf" (temps can be in the low 40's for early tee times), and like me, she thinks it's absolutely perfect. It's breathable, and she can move (i.e., swing the golf club) freely. She has remarked more than a few times about how warm this top keeps her. We are now both big fans of this great product.
