Reima’s material sustainability is based on selecting the materials that are the best fit for purpose. This helps us minimize waste and the environmental footprint of our apparel.


In kids’ clothing, durability is the key to sustainability. The most sustainable way to dress your child, especially for the outdoors, is to buy extra durable clothing.

But how do you know if the fabric is strong? You can’t see, nor feel it. That’s why we use something called the Martindale test, mechanically rubbing every one of our fabrics with sandpaper, to ensure they’re fit for even rough play.

Our minimum Martindale requirement for all jackets is 15,000 rubs and for all pants and overalls the minimum is 30,000 rubs. So in theory, you could slide down a dirt path on your butt at least 30,000 times before the fabric gave in. That’s some tough love, but Reima pants could take it! Martindale results for most products can be found in individual prduct pages.

By making sure our fabrics are fit for purpose – to help kids enjoy the outdoors and an active life to the fullest – we help reduce the waste that would come from buying new clothing because of wear and tear.

Towards greener materials

The textile industry is in the middle of a huge shift towards circularity and climate-friendliness. We think that’s fantastic, which is why we have built a roadmap to increase the share other sustainable materials.

When using synthetic materials such as polyester, we opt for recycled fibers. Recycled polyester has significantly smaller carbon footprint than virgin polyester – making it a preferred choice for our kids’ future! We are systematically increasing the use of recycled fibers: in 2021, 36 % of all our styles (clothing and accessories) are made with recycled fibers (min. 50 % recycled content in main fabric, lining or both). In 2022, this already applies to 48 % of all styles. Starting from our autumn/winter 2022 collection, all the synthetic wadding in our winter gear will also be 100 % recycled.

With natural fibers, such as cotton, we prefer organic. In 2021, all our cotton clothes and most accessories are made of certified organic cotton. These styles represent 10 % of our total collection. By 2023, 100 % of the cotton we use will be certified organic – including also the cotton used in mixed fabrics and linings.

In addition to recycled and organic fabrics, we offer other eco-friendly materials, such as sustainable wood-based materials, responsible wool, bluesign® approved fabrics, and easily recyclable clothing.

Animal rights

Kids love animals and would never hurt them, so it only makes sense that we should protect them from harm. We never use real fur. Down has unmatched insulation capacity, which is why we still use it in our most heavy-duty winter gear. All the down we use is Responsible Down Standard (RDS) certified, to ensure the humane treatment of ducks and geese. RDS also ensures that all down is the byproduct of food production, so there are no additional environmental impacts from it. We only use mulesing-free wool, and we are also increasingly using Responsible Wool Standard (RWS) certified wool – to ensure the welfare of the sheep as well as the land they graze on. We only use real leather in footwear when it is functionally the best choice for the style. Any leather we use is certified to be a by-product of food production, and treated and dyed in an environmentally friendly manner.

Innovating for recyclability

Textiles are a huge waste issue, because unlike an apple, even a simple t-shirt might have too much mixed fibres and prints to be recyclable as a whole. Performance wear is even more difficult to recycle thanks to the different fibres in the lining and shell, the finishings etc, that make the clothing so useful in the first place. That’s why Reima has created the Monomaterial collection: performance wear made of one fabric all the way down to the waterproofing. They’re made to be used by several kids, and then handed back to Reima for recycling back into polymers, so they can be made into new products.

By 2023, our aim is to make 20% of our clothing easily recyclable.
