In 1994, New Zealand native Jeremy Moons was introduced to two sheep farmers who resided on the remote island of Poheunui by his then-girlfriend. The two wool growers – Brian and Fiona Brakenridge – had developed a new type of thermal regulation underwear from Merino wool gathered from their local flock. As an outdoor enthusiast, Moons saw value in this product. Subsequently, in 1995, Icebreaker was formed.
Since then, their products now stretch far beyond Merino wool underwear. They have become a prominent player in the outdoor clothing industry.
Icebreaker specializes in next-to-skin clothing like underwear, socks, base layers, and more. They also offer high-performance outdoor apparel and athletic wear for men, women, and children.
As a result their clothing is great for bot cold-weather and hot-weather base layers. Also, for any on-the-go activities like hiking, backpacking, traveling, and so much more.
Icebreaker Review: What We Like
Icebreaker is a leader in innovation in the outdoor clothing industry. Their products protect against all sorts of weather. They use core-spun nylon to improve durability in much of their fabrics, so your garments will last longer. Icebreaker has even developed a specific base layer system based on fabric density to normalize their product line across different collections.
|Featherweight||120||shirts, lining, shorts||activewear, and summer training|
|Ultralite||150||underwear, baselayers, liners, shirts, sports bras||activewear, travel, hiking, summer activities|
|Lightweight||200||thermals, baselayers, leggings hats, liners, shirts, hoodies, socks||moderate temperature single layer, cold-weather base layer, and travel|
|Midweight||250-260||thermal tops, bottoms, crews, linings||cold-weather base layer and second layer thermal regulation.|
|Midlayer||320-330||hoodies, pullovers, jackets, tights, sweaters, socks||second layer everyday, outdoor, and travel uses.|
|Outerlayer||380||jackets, coats, vests||winter conditions second and third layer.|
In addition to their high-quality products, our favorite aspect of Icebreaker is their extreme commitment to the environment. They focus on sustainability, ethics, transparency, and more. We’ll touch more on that in a bit.
Icebreaker Review: Areas to Improve
It’s hard to find much we don’t like about Icebreaker, but we would have to say that their products are a bit on the expensive side if we had to choose. However, they often have deals and specials regularly. So make sure to regularly frequent their website.
Also, while we have not had durability issues, some users have reported holes or reduced quality after a few months. Much of the time, this lack of durability is directly associated with mishandling the fabric. Ensure that you are caring for your garments properly with our Merino wool buying guide.
*While we don’t feel this constitutes an area of improvement, it’s important to note that some of the Icebreaker products we have ordered in the past have had a 10+-day shipping time. As a result, please plan and purchase your clothing a few weeks before you need it.*
Icebreaker Review: Sustainability
Icebreaker is one of the best Merino wool companies when it comes to the environment. Their philosophy is based 100% around using natural solutions, like Merino wool, to solve real-world problems. They emphasize their commitment to protecting land, animals, and people. If we could give them a grade for their environmental efforts, we’d give out an A++.
According to their website, they take a myriad of concrete steps to help protect the environment.
- Useful ‘Baacode’ provides customers complete traceability of their garments down to the exact wool harvesting farm.
- Concerned about microplastic contamination and vowed to go plastic-free by 2023 by reducing synthetic fibers use.
- Funds research aimed to clean up our global waters.
- Develops natural dyes for garment manufacturing.
- Involves in regenerative farming practices to reduce overgrazing.
- Requires all Merino sheep growers to have a “land environmental plan.”
- Part of the ZQ-standard for Merino wool production.
- All facilities meet ISO 14001 standards for environmental protection.
- Fully engages in the Life Cycle Assessment (LCA) of their materials (ISO 14044).
- Effectively pushes customers toward natural living practices that reduce the consumption of resources.
- Utilizes sustainable product packaging.
- Use “social and environmental responsibility roadmap.”
We probably could go on and on about Icebreaker’s commitment to sustainability, but we think you get the point. If you’d like to learn more about Merino wool’s environmental impacts, we’ve crafted a detailed sustainability guide just for you!
Icebreaker Review: Ethics
Just as Icebreaker is committed to sustainability, they are also highly committed to ethics. They want the Merino sheep to be happy first, and their product comes second.
Icebreaker strictly follows the ‘Five Freedoms of the Flock’ outlined in the ZQ standard, ensuring 100%-mulesing free Merino wool. They also audit their wool growers to ensure they are following the same guidelines.
As for the ethics of their suppliers and manufacturing facilities, Icebreaker carefully watches over the entire process. VF Corporation, their parent company, performs annual and semiannual audits on all of their facilities. They break down their audits into six categories: transparency and compliance, child labor, labor practices, wages & benefits, health & safety, and environment.
According to their latest transparency report, their lowest-scoring audit category was “Transparency and Compliance,” which still scored a 74%.
Overall, Icebreaker takes ethics seriously, and again, we’d have to give them an A+ in this category. If you’re interested in Merino wool production’s full ethical considerations, check out our ethics write-up.
Icebreaker Review: Sourcing
Icebreaker follows the ZQ-standard, which means that the sheep are happy and mulesing-free. They source most of their Merino wool from farmers in New Zealand, consisting of about 140 sourcing farms. These exclusive contracts, worth nearly $50-million, ensure that these farmers follow their strict and ethical practices. You can check out the exact locations of their wool growers on their website.
