Dad deserves better than polyester.

1. Made of 100% natural fibers - not plastic synthetics

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

If he's the dad who reads labels, filters his water, or won't drink from a plastic bottle, his shorts shouldn't be made from one.

Most "performance" shorts are made of plastic — polyester, nylon, spandex. Ryker shorts are made from 100% organic cotton and 100% merino wool. No plastic-based fabrics.

2. Third Party Tested - No Hormone Disrupting Chemicals

If he tracks his sleep, knows his testosterone number, and takes his health seriously, this is the gift that respects that work. Big Brand plastic activewear often contain toxic chemicals like BPA and PFAs - toxic chemicals shown to tank T levels.

Not Ryker. We're third party tested - absolutely ZERO BPA, PFAS or phthalates - so these shorts won't undo the work he's already doing.

3. Naturally Breathable & Sweat Wicking - With No Harmful Chemical Leaching

Whether he saunas, lifts, golfs, or coaches little league, he's sweating in these. With traditional shorts, harmful chemicals may leach when exposed to heat - and can be absorbed into your skin.

Not with Ryker. Naturally breathable & sweat wicking fibers + ZERO hormone disrupting chemicals - so you have nothing to worry about.

4. Fits just like big brands. Without the plastic.

Whether he's a Lulu or Vuori, he won't have to compromise on fit with Ryker.

Ryker shorts fit & perform exactly like his Lulus - same athletic cut and range of motion.

5. Built For the Dads Who optimize everything else

Microscope, scale with beaker, shorts, certificate on a table with testing badge.

He reads ingredient labels. He ditched seed oils. He listens to Huberman.

He needs shorts that actually fit his lifestyle. Ryker uses 100% natural fibers - no polyester or synthetics. Not only that - we 3rd party test our gear - and have absolutely zero BPA, PFAS or phthalates. It's not crazy, it's just the smart choice.
