What we think about when choosing material

What we think about when choosing material

A garment's total environmental footprint is largely traceable to the choice of material. Read more about the materials we work with and the materials we avoid.

- Synthetics
Most of our products are made from polyester. As a fiber, polyester has a long list of pros. Polyester fabrics can be made to be very durable, they dry quickly and they wick away moisture efficiently. A polyester fiber can also be reused again and again, without impairing any of its fantastic properties. Most of our polyester garments are made from recycled fibers, many are recyclable and most are both. Garments made from polyester are also easy to take care of, and since they dry quickly this is yet another benefit for the environment.

Production of polyester require less water to produce than many other fibers, and working closely with our suppliers we can ensure the production is made in a more sustainable way. Polyester can be recycled endlessly in a circular recycling system without lowering the quality. By offering both recycled and recyclable products, we have come close to our goal of offering maximum experiences with minimal environmental impact.

- Natural fibers.
In products where we have chosen to use natural fibers, we primarily use merino wool. Merino wool offers many excellent properties; it can lock in heat even when moist and it naturally repels bacteria, which means unwelcome smells are not an issue. In order to make our wool products more durable and improve properties such as comfort and moisture transport, we add other natural fibers like Lyocell Tencel. In order to ensure that our garments are biodegradable and recyclable, we never mix natural fibers with synthetics.

- Bluesign®
Houdini is a member of Bluesign and as of now we are requiring that new manufacturers comply with bluesign chemical standards. The basic idea behind bluesign is that it combines consumer safety, air and water emissions, the use of chemicals and human rights under a single standard. The bluesign standard guarantees that approved products and production processes do not contain components that are harmful to people or the environment. Read more at www.bluesign.com.

Bluesign in brief:
The basic idea behind Bluesign is that it combines consumer safety, air and water emissions, the use of chemicals and human rights under a single standard. This standard guarantees that approved products and production processes do not contain components that are harmful to people or the environment.

- Anti-odor treatments for clothing.
Today we use a treatment that we call pH Pure™, which lowers the pH value of the fabric and prevents the occurrence of odorous bacteria. This treatment contains no hazardous chemicals and is applied while the yarn for the fabrics is being produced and it will not wash out of the garment.

We are always trying to minimize our impact on the environment. Since recycled and recyclable polyester is one of the materials with lowest environmental footprint and also is a durable fiber, we choose to treat the yarn to not reduce the lifetime of the garment due to smell but that the treatment will stay during the garments entire lifetime.Besides syntheric base layes, we also offer base layers in natural fibers suck as merino wool. We never mix synthetics with natural biodegradable garments since we want to keep the materials either recyclable or biodegradable. The base layers in merino wool is not treated with pH Pure™ since wool have natural anti-odor properties, but is naturally not as strong as polyester fibers. We see that different persons have different requests for base layers, both in terms of style but also function/strength and material. That’s why we offer a different variety of garments, but trying to make them all as gentle to the environment as possible.

- DWR treatments.
Per fluorinated compounds (PFCs) are often used in DWR treatments (durable water repellency) to make fabrics water-resistant. The so-called C8 fluorocarbon based DWR contained PFOA and PFOS, chemicals that is harmful to the environment, animals and people, and among other effects can have a negative impact on reproduction. These substances are used in many areas, such as manufacturing, non-stick treatments in kitchenware, etc.

More previously C8 chemicals were replaced by C6 fluorocarbon-based DWRs that is a shorter fluorocarbon chain and does not contain PFOA or PFOS, but still contain substances that is harmful for the environment.

We currently phased out all our fluorocarbon-based water repellent treatments. Under 2018 we completely phase out fluorocarbons and only use a DWR that is completely free of fluorocarbons.

Now we also offer PFC free re-impregnation in our stores.

We invest a lot of time and effort into our choice of material. If we cannot find materials that live up to our high demands on comfort, function and the environment, we will develop a new material in collaboration with our suppliers. Or we simply don’t produce the product. We never apply for patents for our new materials since we believe that the more companies using functional and environmental materials, the better.
