THE TRUTH ABOUT SAUNA & UNDERWEAR
Most underwear is made entirely of cheap, plastic-based fabrics. Here's why that's a problem:
SAUNAS MAKE YOU SWEAT
Sweat opens your skin and causes it to be significantly more absorbent to whatever it touches. You don’t want to expose them to unnecessary junk (like chemicals in most conventional underwear.)
MADE FOR THE HEAT
Saunas expose your body to high temperatures, so what you wear matters. Choosing breathable, natural materials can help keep things comfortable and minimize unnecessary exposure to synthetic materials while you sweat.
WHAT YOU WEAR MATTERS
Exposure to unnecessary chemicals found in many conventional underwear products may be linked to concerns like decreased testosterone, erectile dysfunction, infertility, certain cancers, and more.
The Comparison
Better Fabric. Better Fit. A Better Environment For Your Boys.

Why NADS
What Your Body Gets Instead.
Every material decision NADS makes has one goal: reduce what your body is exposed to, and improve how you feel wearing it.
DON'T SIT IN PLASTIC AT 200°F
Most underwear is polyester, which is plastic. These are a 100% GOTS-certified organic cotton body. No polyester, no nylon, no unregulated dyes.
BUILT TO GET WET AND GO BACK IN
Bench, plunge, bench again. Cotton takes the water and the heat the way it's supposed to. No clinging, no changing between rounds.
DECENT ENOUGH TO WALK OUT IN
A proper boxer cut in All Day Sauna Co blue. Sauna to plunge to the deck without reaching for a towel.
YOU KNOW WHAT'S AGAINST YOU
GOTS and OEKO-TEX certified, independently audited from fiber to finish. Not a label claim.
