Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.
Merino fibers efficiently manage moisture, absorbing it from your skin and releasing it into the atmosphere. It can absorb up to 35% of its weight in water without feeling wet.
icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.
The thermo-regulation properties of merino wool adapt to your body and external conditions, so you can stay warm in the cold and cool in the heat.
Overall rating: 4.625 / 5 from 8 reviews.

"Great weight. Comfortable. Good fit"
— Linda L. (5/5)
"This is hands down the best thermal I've ever bought. The Icebreaker 260 ZoneKnit seamless long sleeve keeps me super warm during all my winter activities – from early morning walks to skiing. I love the length as it covers me really well and doesn't ride up, which makes it extra comfortable. The fit is spot on, it feels soft against the skin, and it layers perfectly without feeling bulky. It's tough enough for the outdoors but still looks and feels great on its own. Worth every cent – I'll definitely be buying another one!"
— Krit (5/5)
"Love how fitted this top is, nice and warm and a good length too plus I love the Bluey grey colour."
— Sailingtigger (5/5)
"This wasn't a winner for me. Being body hugging it doesn't insulate well. I've worn it and washed it and still has ~some body scent. Color is ok and I think it will last longer than I want! Stick with their merino line!"
— Jen C. (3/5)
"The color turned out to be more of a purple-pink than I anticipated, but I still like it. The fabric is soft and has a yoga-like feel, which is great. My only issue is that it sometimes rides up from my hips to my waist—maybe sizing up could solve that. Overall, it's comfortable, warm, and breathable, making it perfect for my daily walks."
— JJ (4/5)
"Super warm and comfortable! Would purchase again"
— Elle (5/5)
"Baselayer 260 is much warmer than others that I have from Icebreaker. Wish there were more colour options."
— Skibum (5/5)
"To stay warm"
— Woody (5/5)
