Collection: IM BioPerform Sportswear

IM BioPerform offers an unmatched combination of performance factors that you won’t find in other eco alternatives to polyester such as cotton, bamboo or even tencel. Feel free to run faster, jump higher and sweat more - BioPerform has you covered.

Most performance activewear is bad for our skin and health because it’s made using petroleum and plastics. Even the more sustainable options, such as recycled polyester and plastic bottles, release toxic chemicals as we sweat and wash our clothes. Not the ideal choice for clothes we wash repeatedly and wear directly next to our skin.

If you follow the care instructions on the label your sportswear will keep their general shape and size. The garment may shrink a few centimetres once washed but that does not compromise fit because of the high elasticity.

Bioform is made using a natural polyamide that comes from castor beans! There are no animal products used in the making of our sportswear.

If you’ve made a mistake with the sizing, you can exchange your item within 30 days. Please contact customer service to arrange customerservice@innermettle.com
