Why Ryker?

Most big name gym brands make clothes with cheap polyester that can shed microplastics into your skin and is chock full of harsh chemicals.

But you deserve better than cheap, plastic, endocrine disrupting gym clothes.

At Ryker, we make premium, fitted gym clothes with only natural fibers (like bamboo, hemp & cotton), never polyester or other plastic-based, endocrine disrupting chemicals and fibers.

NEVER made with polyester or other plastic-based fibers

Absolutely NO endocrine disrupting chemicals or fibers

100% Natural Fibers: From the Earth, not from a lab

"I didn't realize my gym clothes were literally made of plastic..."

Most big brands (yes, even the brands you love!) use synthetic fibers - like polyester, elastane and spandex

What they don't tell you is these fibers are actually made of plastic.

We wanted something better - so we made Ryker.

Fitted gym clothes made with 100% natural fibers like bamboo, hemp & cotton.

...It's time to ditch your plastic gym clothes

"Finally something that's polyester-free. Also it's nicely fitted to hug your arms just like other brands. Suprisingly comfortable - definitely glad I made the switch."

- Julian D.

Comfortable & Breathable

"I wanted to switch from polyester but was worried bamboo and cotton wouldn't be as comfortable. I was so wrong! It's soft and stretchy - I wear them daily to lift!"

- Derrick W.

No Microplastics

"After learning about microplastics in athletic clothing I tried to find a good brand without them. Happy I found Ryker! Very comfortable - I have 2 shirts and a pair of joggers!"

- Ethan K.

What's Wrong With Polyester?

The reality is simple: Polyester is made of plastic. That means every time you toss on big brand gym clothes you're working out (and sweating) in plastic.

And when you wash it? The cheap polyester fibers break down, shedding microplastics into the water supply (and your skin!).

Seriously, our customers love us...
