Too much
heat.
Down there.

Day 1
Heat
strikes.
Scrotal temperature spikes above optimal within minutes of entering the sauna. Sperm production is already compromised.

Testos­terone
drops.
Leydig cells respond to sustained heat stress by reducing testosterone synthesis. The effect is measurable — and invisible.

+ The 90-day reality

What you do
today shows up
in 3 months.

Sperm takes 90 days to fully mature. Every unprotected sauna session corrupts that cycle — silently, cumulatively. By the time you notice, months of damage have compounded.

⚠ The silent cost
No pain. No symptoms. No warning. Temperature is one of the few variables you can control — starting with your next session.
AeroShield™ Pro Briefs

+ The solution

The
AeroShield™
System.

A cooling brief engineered for men who sauna. One simple ritual — freeze the insert, slide it in, go. Keeps scrotal temperature within the safe range the entire session.

01 —
Freeze.
Pop the AeroShield™ cooling insert in the freezer before your session. That's the whole prep.
02 —
Insert.
Slide it into the secure zip pocket built into the brief. Locks in place. Stays there the whole session.
03 —
Go.
Sauna the way you want. Stay cool where it counts. Come out with your biology intact.
