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.

This sweater is SO soft! I wore it for Christmas and my granddaughter could not stop snuggling me and rubbing it. It's also warm and comfortable, even around the neck. Looks great with leggings and fitted jeans. I love it.

A perfect 3 season skirt. Great with tights in the winter, easy to throw on over yoga leggings. Wool is very light but still hangs well.

Great Great Great I have been searching high and low for wool blend slacks to wear out (casually). These are it. I usually wear a 10-12 in slacks and medium was a great fit. Not too tight, skims your torso with nice ankle finish. Great with tunic tops or button up crop sweaters. They are a wool blend and if you are sensitive, I would caution. In the cold, they feel warm. I am curvy in my early 60's and feel totally at ease with the look. Wish I had gotten them for a recent trip to northern Italy, they would have been great. Buying more today.

I ordered this top in small. I am 130lbs, 5'6". The small fit perfect. I bought this top for a ski base layer. I like my layers to be super smooth and comfy. The wool is super soft but I realize I am not a fan of the 1/4 zip. it feels weird against my chest and I think i would have to wear a thin crew neck layer under it to be comfortable and that would defeat the purpose of it being a base layer. Otherwise it seemed really well made and the black color is super deep black. it is stylish just not practical for my needs.

This fit very small. I usually wear a small, so that's what I ordered. This skirt fit like an XS. Also, the side zipper didn't lie flat, so the overall look was not very stylish. It was also too short for my liking. I purchased the Prana Diva Wrap Skirt which is perfect! Zappos is the best! :)

This was soft and everywhere but the one area that I will mention in a second was great BUT I had to return because the seam from the waistband straight down the front cut into my "nether" regions which made it uncomfortable and less than lady-friendly. Maybe it's just my frame but this is the first time I have had something cause such discomfort.

Excellent fit without pulling anywhere (I wear a size 2-4 in blouses/shirts). It's light, warm, not itchy and does not hold body odors. I can hang it up after wearing it several times without needing to wash it, which is a plus for one who travels (the reason I bought it, actually). So - very pleased and the price was appropriate.

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 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.

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!
