6 Reasons to Ditch Your Plastic Activewear
Your gym shorts are shedding microplastics into your skin every workout. Here's what polyester is really doing to your body, and why we built something better.
Most gym shorts are made from polyester. Polyester is plastic. Here's what that actually means for your body and the planet.
Microplastics Are Getting Into Your Body
Your Shorts Are Full of Chemicals You Can't See
That Post-Workout Rash? It's Probably the Fabric.
Polyester Stinks. Literally.
Synthetic Textiles Are Polluting the Ocean
There's a Better Option. It Already Exists.
Quad Short: Natural Fiber Short
Don't Take Our Word for It
"Insanely hard to find athletic wear not made of polyester, and these are TOP TIER"
These shorts are the best! It's insanely hard to find athletic wear that is not made of polyester and these are TOP TIER. The wool lining is so soft and amazing to workout in.
"No better feeling than natural fibers against your skin"
There is no better feeling than clean, organic, natural fibers against your skin. These shorts make me happy.
"Noticeable difference in my energy levels"
Got my first full lift in today since buying these shorts and felt a noticeable difference in my energy levels. There is something about wearing natural fibers that amplifies your energy and these shorts give that feeling.

Quad Short vs. Polyester Performance Shorts
How the Quad Short compares to synthetic activewear.
Real People. Real Reviews.
"Best athletic shorts ever. Really high quality."
I think these are the best athletic shorts ever. They feel really high quality... love the ZIPPERED pockets... Yahli was super fast to respond and ship everything out. Highly recommend getting these.
"Phasing out all my other shorts for these"
Just got my second pair! Slowly but surely, I'm going to phase out all my other shorts... They hold up great... and feel as comfy as any other performance shorts I've worn over the years.
"Weightlifting, hiking Camelback Mountain. Must have."
Have worn the shorts for both weightlifting and hiking (Camelback Mountain). Love the comfort and versatility. Must have for anyone with active lifestyle.
"All natural fibre training short with great customer service"
Great pair of shorts! Been looking for an all natural fibre training short for a while and have got these in black. Super comfortable, great wicking layer with the merino wool and great customer service! Would recommend.
Every pair of shorts in my drawer was polyester. Shedding microplastics, trapping bacteria, coated in chemicals. I wanted activewear I could actually trust against my skin. So I built the Quad Short: organic cotton shell, merino wool liner, zero synthetic materials.
Stop putting plastic on your skin.
The Quad Short. Organic cotton. Merino wool. Zero synthetics. Third-party certified.
