Women’s Merino 260 Oasis Long Sleeve Half Zip Thermal Top

$219.99

Details

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.

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.

If you have any question please reach out to ecom.nz@icebreaker.com

Why choose icebreaker merino wool?

Machine washable

Reviews

Great shirt but rubber stamp is irritating

"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)

Great fit, really warm, love

"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."

Felicia E. (5/5)

Cody colourful half zip

"Love my new icebreaker 1/2 zip. Fun colour change. I have a few tops and like the warmth and breathable fabric"

Kim C. (5/5)

Love it. Soft and warm.

"Love it. Soft and warm."

Anna M. (5/5)

So good

"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)

Feels so good! Looks good too!

"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)

This is my sixth Merino 260 tech long sleeve half zip therma

"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"

HyggeHoney (5/5)

Yes

"The best merino top I've bought. I live in it every day. More colours please."

Angi (5/5)

Zip regulates temp

"Better than the other 260 tech tops for dog walking in winter, as the zip allows me to regulate body temp, and has the advantage of a high neck when needed which is most of the time this winter."

Wens (5/5)

too long

"I have been very loyal IB customer for 10+ years. I found IB is making tops longer, and longer, and longer, and longer. Why? Why Why? I also bought a lot the last few years for families who are shorter and bigger in shape. But even me, 168cm 58kg, its tooooo long and no way my families can wear IB any more. Please, IB, read many reviews that people complain about length, you really have to do something as I am seeing more and more nice and pretty merino by other brands in the market and I am struggling if I should try other brands. For this one I bought L but I also bought M from retailer, both are too long."
