About
Sauna is good for you. Except for one thing.
We build gear for men who refuse to choose between short-term health and their long-term future.
Our timeline
From problem to product.
2023
The problem
Two founders going through IVF. Advised to stop saunaing. Nobody stops their sauna.
2024
The prototype
First samples with a freezable pack in a textile engineering lab. 47 iterations on the pouch alone.
2025
The test
Independent validation with intra-scrotal temperature measurement. Result: 95°F maintained for 30 minutes.
2026
The product
Sauna Theory launches in the Dutch market. First 10,000 pairs sold within 6 months.
Our principles
Three rules. The rest follows.
01
Evidence over promises
Every claim is tied to peer-reviewed research or our own validated tests.
02
Comfort is non-negotiable
A healthy product that's uncomfortable doesn't get worn. We don't accept compromise.
03
Fair prices
No middlemen, no retail markup. Direct-to-consumer, built to last.
