Studies show that even a 2°C rise can cut sperm activity by up to 30%.
Surface temperature measured at the scrotal skin. Internal testicular temperature is naturally ~2–3°C lower. *

PRODUCT DESCRIPTION
HeatGuard Sauna Shorts are designed to reduce direct heat exposure during sauna use.
An engineered inner layer system creates a thermal buffer in the front pouch area, helping limit overheating while maintaining comfort and breathability.
While optimized for sauna environments, HeatGuard Shorts are also fully functional swim shorts for everyday use — combining regular swimwear comfort with added thermal protection when exposed to high heat.
HOW HEATGUARD WORKS
Engineered inner layers work together to manage heat and moisture in high-temperature environments.
Inner Layer
Keeps skin dry by quickly absorbing and wicking away sweat.
Air Layer
Creates air circulation, allowing heat and moisture to escape without direct contact with the body.
Outer Layer
Reflects infrared heat away from the body, reducing direct heat exposure.

Frequently asked questions
How is TermoMen better than using a towel in the sauna?
- A towel does not block heat. It absorbs moisture, heats up quickly, and allows direct heat to pass through to the body
- TermoMen is specifically designed to reflect heat, creating a functional barrier that reduces direct heat exposure to the front area.
- Instead of absorbing heat like a towel, TermoMen controls and deflects it.
How does TermoMen reflect heat?
TermoMen uses:
- Purpose selected heat resistant materials
- A structured front panel that reduces direct heat transfer
- An anatomical shape that prevents fabric from being pressed tightly against the body
- This combination allows heat to beredirected rather than absorbed.
Will TermoMen overheat in high-temperature saunas?
No.
TermoMen is designed to manage heat, not trap it. The materials allow airflow and moisture release while reducing direct heat impact.
It stays comfortable even in high-temperature sauna environments (90°C / 194°F and above).
Why does this matter in the sauna?
The male reproductive area is highly sensitive to heat. Its reproductive function depends on maintaining a lower temperature than the rest of the body.
Prolonged exposure to direct sauna heat can negatively affect male reproductive function, especially during long or repeated sessions.
TermoMen helps by:
Reducing direct heat exposure to the male reproductive area by creating a thermal barrier.
This helps limit overheating, supports more balanced conditions for normal reproductive function, and improves overall comfort during sauna sessions — allowing you to stay longer without localized heat stress.
Is TermoMen designed specifically for men’s anatomy?
Yes.
Unlike towels or generic sauna wear, TermoMen is engineered around male anatomy.
It features:
- An anatomical front structure (not a flat panel)
- Reduced direct compression
- A shape that follows natural movement rather than symmetry
- This design improves stability, comfort, and heat control during sauna and contrast rituals.
