Perfect thickness and warmth for cold winter skiing
The 260 thickness is perfect for cold winter skiing. It's thin enough that I don't even notice it yet plenty warm to keep you going all day. Especially like the half-zip top adjustment if you start to get hot.

Nice Garment - Too Long!
I order the tech 150 products in medium and the length is perfect. Why is fit so inconsistent with Icebreaker products? Sleeves and torso both too long on this product!

Baselayers kept me warm and dry on ski days. Used them for lift and hike-to skiing. Worked great. Didn’t smell. Washed easily and dry quickly.

Comfortable And Warm. Looks great. Living in northern Wisconsin this is a great piece to keep me warm! No downside to this shirt.

Base layer
A welcome addition to my cold weather layering. Nothing like merino. I would appreciate if icebreaker would make one level heavier weight.

The most comfortable Merino product I own
I ski for a living in the mountains. The Icebreaker 260 Tech Half Zip fits like a dream. It isn't baggy like some other Merino products I own from other companies. I Highly Recommend. With this purchase, I'm officially a convert to Icebreaker Merino products. Regardless of whether you are a beginner, an expert, or somewhere in between, this product will not let you down.
