Icebreaker

Icebreaker Logo
Our role is not to create the latest “technical” fibre. Nature has already done that, and without an oil rig in sight.

Merino wool was born not in a lab, but in the mountains of New Zealand. The Icebreaker fibre factory works 24 hours a day, on the back of a sheep.

Sustainability is at the heart of Icebreaker, and we aim for profitable sustainability — a business model that balances ecology with economy. It’s possible because nature is an astonishing designer. Everything it creates is simple, efficient and beautiful.

We believe nature is a powerful force that is within us and around us. We have harnessed this force to become the passionate world leader in merino.

IT’S ABOUT OUR RELATIONSHIP WITH NATURE,
AND TO EACH OTHER
That’s not a slogan: it’s the way we think.

We started with an inquiry about how nature works, and how we interact with nature. Our contract isn’t just with our customers, but with the environment.

Customers increasingly care about where the things they buy come from. They want to know about the ethical commitment of the companies they buy from, and what impact their purchases will have on the planet.

We know we’ve got lots of work ahead, but we’re committed to a sustainable business model that doesn’t put profits ahead of the environment.

I think I've had this for about a year now and I love it! I wear it to keep my core warm when it feels chilly outside and it's awesome. Fits snug, is comfortable and it does not itch. I usually wear a small in shirts but ordered this in a medium and it was perfect! I wash it in the machine in a laundry bag and then hang to dry. I love it so much I am going to order another one!

I like this shirt but would like it even more if it didn’t develop holes after so many washes. Will probably stick with Smartwool for now on because they are adding nylon to their 150 weight wools to prolong longevity. Would be nice to see Icebreaker step up their game because I have many Icebreaker pieces I absolutely love. Would still recommend pure merino 150 weight to people concerned about upmost comfort tho.

Wool isn’t my favorite, but I like this so much better than the SmartWool equivalent; it’s softer and more stylish. The zip collar makes it super cute as everyday wear, and flattering overall.

I bought these for travel, but I ended up replacing all of my bikini underwear with these. They are fantastic-- super comfortable, wear well, and don't feel disgusting/dry quickly if you sweat in them.

Very thick and stretchy. The hood fits well. More on the cool side for such a thick fabric, because of all the tencel. It was OK, but I'm not a hoodie person, I guess. I'm 5'5" tall, 138 lbs, and 38-32-40 and a size 10, but I always buy a large in Icebreaker, because I don't like wool skin tight on me.

I love this bra. Wore it every day 3 weeks in Myanmar. It is soft and so comfortable, packs small, keeps me very cool, is comfortable, doesn't stink, dried quickly. It has slots to insert bra pads if you want a little more coverage or shape. I would day it provides light support, good for hiking, climbing, yoga, but not for running. I love this bra so much, i bought another one.

These are not really an everyday legging, they are too see-through. They say "base layer" on them not everyday legging too. I'm looking for something I can wear as just a legging.

Great base layer for cold temperatures, I have been wearing it for 4 or 5 days straight under various tops and it doesn't stink at all. Fit is as expected, it is snug but that is what I want from a base layer. I ordered a small, 5'4" and 125 lb with 34C chest and it is perfect.

I was leary of purchasing these as I own 4 pair of Smartwool Hipkini and loved them. I was concerned that these may not fit as well. They fit perfectly, don't ride up and are sexier!

I had hesitated many times about buying this brand because it seemed to me a little bit too expensive. I couldn't have been more mistaken. This piece of undergarment not only is super comfy but also is perfect for traveling, hiking and every kind of outdoorsy activity. It let's your skin breathe, when washed, it dries very fast and it repels odors. I recommend it 100%.

I love these! My hips are 35 inches, waist is 25 inches. An XS fit me perfectly. It has a slightly higher rise than other thongs, but it's pretty easy to "adjust" to a lower rise :) I love this thong for exercising because it keeps me from getting sweaty and smelly like regular thongs. Highly recommend!

I love these and have several pair. They are definitely moisture-wicking and dry quickly. (Texas summers). No itch whatsoever, but I do use Charlie's Soap to wash and I hang to dry.

This is true of many boy shorts - just not a good fit for big thighs, they roll up and are uncomfortable.
