Frequently asked questions
Why wear 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.
Can I expect any shrinkage to my sportswear?
If you follow the care instructions on the label your sportswear will keep their general shape and size. The garment may shrink a few centimeters once washed but that does not compromise fit because of the high elasticity.
Is BioPerform sportswear vegan friendly?
Bioform is made using a natural polyamide that comes from castor beans! There are no animal products used in the making of our sportswear.
Which countries does BioPerform sportswear ship to?
Inner Mettle products ship worldwide, import duties and taxes are included for the USA, Canada and UK. Shipping costs are visible during the checkout process.

How do I care for my BioPerform sportswear?
BioPerform leggings can be laundered at home using hot water and regular home detergent, or by your commercial laundry service provider, in an open pocket washer/extractor. Do not launder in commercial tunnel washers. Do not use any fabric softeners. Do not use chlorine bleach as it may degrade the fabric over time.
