What Makes Our Activewear So Sustainable?

Made for life InMotion. Learn what makes our activewear so sustainably unique.

Our goal for the InMotion Collection was simple: give our community the most sustainable activewear out there without sacrificing even an ounce of comfort.

We designed InMotion to support you in everything that makes you feel, well, like you. Whether that’s getting on a spin bike, meditating, cooking, or having coffee with friends, we’ve got you. Plus, in addition to supporting all the ways you move through life, the InMotion Collection ensures your impact on the planet is as gentle as possible.

How It’s Made

From recycled post-consumer waste to organic, ethically sourced fibres, all the materials used in our InMotion collection are movement-approved and planet-friendly.

REPREVE® is the foundational fabric in our InMotion line. Unlike other recycled polyesters, REPREVE® is unique as it comes from 100% post-consumer garments, meaning that instead of clogging up landfills, old clothes become new ones.

It works like this:

  • Used polyester garments get recovered.
  • These garments then get broken down to remove any impurities.
  • A new polyester yarn gets created from the old materials.
  • This yarn gets spun into fabric (which is way less harsh on the planet than its pure, petroleum-based counterparts).
  • Garments that would have otherwise ended up in a landfill get a new life in your closet.

What Makes InMotion So Sustainable?

Pretty cool, right? Not only does this process divert huge amounts of waste from landfills, but it also reduces CO2 emissions by 80% compared to your average activewear production. Most activewear is made from polyester, which usually comes from petroleum — the same stuff that makes plastic. Creating typical polyester fibre is a carbon-intensive process that’s considered non-renewable.

But by breaking these garments down, we’re able to produce a material that brings us that much closer to a fully closed-loop production process — which in turn creates less and less need for new, virgin materials in the world. Pair this with drirelease® technology that skips the harmful chemicals and helps control odour, moisture and bacteria, and trees planted for every purchase, and you’ve got the perfect everyday activewear for you and the planet.

Each InMotion piece is also eligible for our take-back program, Circularity by tentree. This program repurposes and recycles your old tentree clothing, so that nothing ends up in landfills. Simply create an account, print off a free shipping label, mail your pieces back to us, and we’ll do the rest to ensure they are either responsibly recycled or resold in our consignment shop.

Sustainable Care Tips

Creating sustainable apparel doesn’t start and end with manufacturing. A product’s impact on the planet actually depends a lot on how you care for it. Things like washing, the item’s life-span in your closet, and where it goes once you’re done with it all factor into the sustainability equation.

One of the key problems with washing your stuff too frequently is producing microfibre shedding. Microfibre shedding is when tiny fibres from your clothing shed, typically through washing cycles, and make their way into waterways. This can cause really big problems for marine life and the overall health of our oceans and rivers. The good news is that fabrics with tighter knits and smoother surfaces (like the fabric we use for InMotion) produce less shedding.

That being said, any inclination to protect our planet is a good one. We wanted to share a few tips for extending the life of your new InMotion pieces and reducing their microfibre shed. These tips are great for all your apparel care and will seriously reduce your footprint over time.

  • Wash your clothing less. Try using a fabric freshener between washes like this one from The Laundress to keep things smelling fresh!
  • Using a light-duty liquid detergent prevents fabric stripping and extends its life.
  • Wash in cold water always!
  • Use a GuppyFriend bag in the wash to reduce microfibre pollution in waterways.
  • Re-sell, recycle, or repurpose your clothes once you’re done with them to avoid filling up landfills.


The best thing about InMotion is that it feels, dare we say, even better than the activewear you might already have. It’s super soft, super stretchy, and hugs you just the way you want to be hugged. We’re so excited for you to try InMotion and discover just how comfortable making sustainable choices can be. There are a million ways to move. What will you choose?
