Athletic wear has gone through some changes over the years. While I don't come from a conventionally athletic family, we did hike + bike, take long walks + cross-country ski. I took tennis + swimming lessons every summer growing up, but I don't really remember having any special athletic wear, besides what we called 'tennis shoes'. I do remember my dad having a pair of high top Chuck Taylors for exercise. My sisters sported knee high tube socks with their gym shorts in the seventies (not necessarily for athletic purposes). Oversized polyester Umbros were all the rage whether one played soccer or not, when I was in high school. Somewhere along the athletic wear line cotton t-shirts gave way to wicking poly shirts, lycra + spandex added a whole new dimension of possibility in fit, and recycled plastic bottles became fleece.
Now we know that tiny plastic microfibers from that fleece shed with each and every wash. One study found these plastic microfibers in 67% of the fish studied + bound for human consumption in California. Polyester, nylon, and lycra/spandex are fabrics woven from long, thin plastic fibers (derived from crude oil). While these fabric innovations may make great performance fabrics for our workouts, they may not be so great for our health or the health of the planet in the end. These chemical compounds are hazardous in production and will be with us long after we are finished with them. Update 1/2018: Plastic fibers have been found in 83% of drinking water tested worldwide + 94% in the USA. Most of this plastic fiber escapes during the washing of synthetic clothing.
While polyester seems to be the most common fiber when it comes to athletic wear, natural fiber options are (not surprisingly) cropping back up in many ethical circles. It is difficult to replicate the elastic nature of lycra or spandex desired in much athletic clothing, so it can be tricky to find 100% natural fiber active wear. I was able to find a few options, however. It can take a little digging to find the 100% natural items even on some of the websites listed here, but it is possible. When these workout pieces have reached the end of their usefulness as clothing (and then rags), the bits of elastic could be cut out and they could be composted.

If the goal is to buy an entirely compostable garment, I would caution about the probability that these pieces are sewn with polyester thread in order to increase durability. Pansy does proclaim proudly that "everything we make can be thrown on your compost pile + become part of the earth again"! I tried to mostly avoid picturing items with zippers, snaps, elastic and grommets, because they would also not be compostable (but could be cut out before composting).
One way to avoid all of those items (choose cotton thread) would be to sew your own activewear out of organic cotton, hemp, or wool with the help of one of these sewing patterns:

Nau and Icebreaker have a focus on natural fibers, but the sewing origins are not apparent from their websites. Icebreaker does state, "we go out of our way to make sure all of our sewing and finishing is undertaken in an environmentally and socially responsible manner."
All photos are from the brands' websites. I will link to this post on the ethical brands page, so it will be easily accessed when needed.
Sweat on, friends!
