Do you REALLY want to wear plastic in the sauna?

1. polyester is literally just plastic

A man sits on a wooden bench with his shorts and upper legs wrapped in plastic film.

Those "performance shorts"? Just plastic in disguise. Often the same type of plastic that water bottles are made of. Do you really want to wear plastic in the sauna?

2. Polyester 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!

3. Heat + Sweat Increase Chemical Exposure

When you get hot & sweaty in the sauna, your pores open up.

At the same time, sauna heat can cause those hormone disrupting chemicals to off gas from your polyester shorts - making it easy to leach into your skin.

4. These Toxic Chemicals May Affect Your Testosterone

Headlines about chemicals in plastic lowering testosterone, shown over a photo of a person's muscular back in a gym.

Studies show these toxic chemicals (like BPA) are hormone disruptors - they can mess with your testosterone levels - even in small doses.

5. You know you shouldn't microwave plastic - so why microwave yourself in plastic?

You probably don't microwave plastic. But that's literally what you're doing to your body when you rock traditional gym shorts in the sauna.

So what should you wear instead?

$99.00 for a pair of shorts.

$99 for a pair of shorts?! I went back and forth on these for about a week because, damn, that’s a lot for shorts.

Then they arrived.

As soon as I felt them, I got it. Man, these things are soft and comfortable. Now when I put on my old shorts from the big-name company, they feel like I’m wearing a plastic bottle.

Ryker’s are officially my new favorite shorts. I like them so much, I’m getting a pair for my nephew now too.

Yeah, they’re expensive—but I’d buy them again.

Worth every penny

I’ll be honest, I hesitated before pulling the trigger on these because of the price — Ryker shorts aren’t cheap, and I’ve been burned before by “premium” athletic wear that doesn’t actually perform any better than the $25 stuff. These are different.
I wear them for lifting (3-on-2-off split), longer bike rides, and just knocking around the house, and the difference in comfort is immediately noticeable — no chafing, no weird bunching, and the fabric breathes way better than I expected for something this substantial. The fit holds up whether I’m under a bar or on the bike for 15+ miles, which is more than I can say for other brands I’ve tried.
Are they expensive? Yes. Do I regret buying them? Not even a little. This is one of those cases where you actually get what you pay for — the quality is obvious the second you put them on, and they’ve held their shape wash after wash so far.
I’m planning to put these through real long-term use — daily training, higher mileage rides, the works — so I’ll come back and update this review after 3 months of consistent wear to report on durability. So far, though, I’m sold. Ryker please contact me when able.

Awesome, but sized down

Great shorts that hold up even after many washes! I would suggest getting the smaller size if you're between sizes like I am. I'm 6 foot 2, 200 lbs and the medium is much better than the large.

Worth it

I had been looking for something like these shorts for awhile. I held out for some time but finally decided to invest the $$ into a better/safer option. Very soft and comfortable. Hopefully they come out with shirts
