Do you REALLY want to workout in plastic?
1. polyester is literally just plastic
Those "performance shorts"? Just plastic in disguise. Often the same type of plastic that water bottles are made of. If you avoid those, why wear it on your skin?
2. Polyester doesn't breathe - and feels synthetic & clammy
Polyester fabric blocks airflow, trapping heat against your skin. Leading to that synthetic, clammy feeling you hate.
3. It doesn't wick sweat - unless you add chemicals
"Moisture wicking" synthetic fabrics are just marketing.
Most polyester shorts rely on chemical finishes that just move moisture around - instead of combatting it at the fiber level.
Not only that - many of these coatings are laced with BPA & PFAs (hormone disrupting chemicals).
4. Polyester smells horrible
Ever notice what happens when you forget to wash your shorts for a day or two? They REAK.
This odor isn’t caused by sweat.
It’s caused by bacteria — and bacteria thrive in synthetic fabrics.
THAT'S why polyester shorts smell after one wear.
4. May Contain high levels of hormone disrupting chemicals
A shocking study found that 100+ activewear brands contained high levels of BPA - some even have 40x the legal limit! BPA can mess with your testosterone - and has been shown the leach through skin contact!
5. Polyester sheds microplastics
Every time you wear polyester shorts, tiny microplastics shed from the fabric onto your skin. And when you sweat - your pores open up - making you even more susceptible to these microplastics & toxic chemicals!
6. Polyester feels synthetic - like you're wearing a trash bag
Go feel your favorite pair of "performance shorts". Feel that scratchy, plastic-y feeling?
What's "performance" about that?
7. Polyester has potential fertility impacts
A groundbreaking study showed wearing polyester underwear made men azoospermic - meaning their sperm count dropped to zero. Not only that - it caused their balls to shrink too.
8. polyester is dirt cheap - but big brands chage a HUGE markup
Polyester shorts are incredibly cheap to make (ask us how we know 😂)
Yet big brands charge you a 10x markup on it (is a swoosh worth it?). Stop overpaying for plastic.
9. Polyester can irritate skin
If you’ve dealt with chafing or bright red irritation, your shorts may be part of the problem.
When sweat and heat stay trapped, irritation and chafing become more likely — especially during movement.
10. Natural alternatives exist - for the same price and better performance
You don't need "performance" fabric. You need REAL fabric.
Ryker's gear performs BETTER than synthetics - and is priced comparatively to Lulu, Vuori, and other "performance" brands.
So what should you wear instead?
