We’ve recently updated this style from 260 Tech to 260 Oasis. While the name has changed, the product hasn’t. It’s built with the exact same design, composition, quality and performance that define this style. As we move through this transition, new and old packaging will be shipped randomly, and some items may still arrive labelled 260 Tech on packaging or swing tags. We know that can be confusing, but rest assured, you’ve received the right product.
A warm and comfortable merino base layer for the coldest months of the year, the Merino 260 Oasis Long Sleeve Half Zip is a go-to piece for winter layering—ideal for skiing, snowshoeing and other cold-weather pursuits.

"Love this piece. Have another in blue. It is great as a base layer or on its own if it is not too cold. Use it for birding on the Pacific coast when the winds make it nippy outside. It washes well and I hang it to dry. I am 5’3” and weigh 128# and bought a small. Fits great. It does run a tad long but that does not bother me — keeps my butt warm."

"I love this short it is soft and warm and the zipper allowed my to be warmer or cooler without removing the shirt. The stamped tag however is itchy. Please go back to tags I can cut off on the inside and the small icebreaker tab on the outside along the seam so identification isn't lost."
— AF (4/5)
"This is a real classic. I find it hard not to just put it on every chilly day no matter what I’m doing! It’s soft, light, but so warm. I layer mine over a 100% merino tshirt if the conditions are cold. It’s my second one of these (first one shrunk after 10 years, probably my fault for washing improperly)."
— Stephanie C. (5/5)
"Great fit, really warm, love the color. I wish the tags were sustainable and not so itchy that I have to cut them out. Print “100% wool” in the neck so this crucial information isn’t lost."

"Just what’s needed for cool autumn and cold winter days in Minnesota. Great fit and feel. Longer zipper a big plus."

"I love these icebreaker thermals so much I've bought 4 over one winter and I wear two at a time layered up. I have super sensitive skin and they are so lovely and smooth and soft, warm and breathable"
— Estella (5/5)
"I bought this top to go under clothing for layering to wear as pillion on a motorbike in cool weather. I love the zip up neck of this top - it looks like a tidy collar when unzipped. It satisfies my search for a warm layer that keeps my shoulders and neck warm on the bike. I'd love to buy this in other colours."
— Lyn (5/5)
"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"
