"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."

"Super warm and comfortable! Would purchase again"
— Elle (5/5)
"I bought this shirt over the other 260 options because the matching leggings are 25"", a welcome option for someone under 5'4 like myself. That said, the sleeves go to my first knuckles, and the shirt extends past my butt. It's also snug in the arms, shoulders and chest while being too loose in the waist, although his could just be due to my body type. Not quite uncomfortably snug, but the wider waist does create some boxiness. Despite that, I like the shirt: it's cozy, comfortable and the blueish grey hue is really nice in person. I do wish that the brand would have dedicated petite options, though."
— PG (3/5)
"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)
