Sustainable, responsible, and eco-friendly: the promises of Icebreaker Base Layers

The brand Icebreaker was founded in 1995 by Jeremy Moon, in the heart of New Zealand. Icebreaker aims to create more sustainable and environmentally friendly clothing for your outdoor adventures such as trail running or ski touring. The first Icebreaker Base Layers were created in 1996 and gave birth to the very first natural layering system. 

The Icebreaker Base Layers are designed to meet the needs of outdoor athletes. Merino wool is known for being a very warm, breathable fibre that retains no unpleasant odours. This is ideal when you want to go hiking, trekking, or skiing. 

With the primary goal of designing the best Icebreaker Base Layers and preserving the quality of the merino wool used, the brand has committed to long-term partnerships with New Zealand farmers and local businesses. 

The Icebreaker Base Layers are recognised worldwide for their quality. The brand has expanded its range and also offers hiking socks, gloves, and beanies for your favourite outdoor activities. 

Choosing Icebreaker Base Layers also means committing to a sustainable, responsible, and eco-friendly brand. Icebreaker is dedicated to the wool industry and animal welfare. It has banned the practice of mulesing among its farmers, a practice that jeopardises the lives of merino sheep. 

By 2023, all Icebreaker Base Layers and products from the brand will be entirely plastic-free. Icebreaker has developed fabrics made from plant fibres, such as Lyocell or Tencel, to continue its innovation and achieve its main goal: to become a sustainable and entirely natural brand. 

How to choose your Icebreaker Base Layers wisely?

The Icebreaker Base Layers are the first layer that will be in contact with your skin: boxers, briefs, sports bras, or long-sleeved technical underwear. In addition to providing you with exceptional freedom of movement, the Icebreaker Base Layers perfectly absorb sweat and resist unpleasant odours. They are true essentials throughout your days, whether for sports or daily wear. 

There are several ranges of Icebreaker Base Layers. To best choose your ski or hiking base layers, we recommend looking at the fabric weight. The higher the weight, the more your Icebreaker technical underwear will be suitable for extreme cold. 

Icebreaker boxers and sports bras generally have a weight of 120 to 150, which is ideal for staying cool in both winter and summer. For more active sports activities like ski touring, we recommend a weight of 200 to 250, which are extremely versatile base layers. 

Some ranges of Icebreaker Base Layers are more suited to certain sports activities. They do not all use the same technologies and are not made from the same materials. For cooler days, opt for 100% merino base layers; for warmer days or more intense activities, merino and natural fibre base layers are recommended. 

For exceptional freedom of movement in daily life or during your sports activities, we recommend the Icebreaker Anatomica range. These are very versatile, comfortable, and breathable Icebreaker Base Layers

The Icebreaker Anatomica Boxers are perfect for all your sports adventures. They are very durable and feature flat seams for maximum comfort. The Icebreaker Anatomica Short Sleeve Crewe in Merino will also become a staple in your sports wardrobe. Its double composition of merino wool and nylon fibres ensures perfect thermal regulation and great breathability.  

The Icebreaker Oasis range will be the most versatile. The high and low merino base layers will adapt perfectly to all your activities in winter and summer. The Icebreaker 200 Oasis Long Sleeve Crewe is a true must-have from the brand. This Icebreaker Base Layer with flat seams has proven itself in both hiking and skiing. 

For warm summer treks, we recommend the Icebreaker Cool-Lite Sphere Short Sleeve Low Crewe, made from merino wool and Lyocell (a synthetic wood fibre). If the weather is expected to be cooler, opt for the Icebreaker Tech Lite SS Low Crewe, made entirely from merino wool and warmer. The Icebreaker t-shirts come in various colours and patterns, and the brand is one of the first to print patterns on merino wool.
