Stop choosing between your health routine and your fertility.
High-heat exposure is proven to suppress sperm health starting from even a single sauna session. It can take men multiple months to recover their sperm count and that counter resets each time you sauna. Get the longevity benefits of the heat without the biological cost. Our targeted cooling briefs protect your fertility so you can focus on enjoying the sauna with peace of mind.
Ultra-Breathable Comfort. Zero Synthetics.
When you’re in a 200°F sauna, your pores are wide open, so the material on your skin matters.
SaunaArmor™ Briefs are crafted from 100% Premium Cotton to ensure maximum breathability and a microplastic-free experience for your skin.
Most underwear will use 5-10% cotton/spandex blend as a compromise for stretch and durability. We chose to go all in on natural fabrics.
Pure cotton means:
- Zero microplastics absorbed through your skin
- Maximum airflow in high heat
- Natural moisture wicking
- Soft, non-irritating fabric where it matters most
Targeted Protection so you can Sauna for Longer
A specialized cooling pouch that insulates without restricting. Keep your boys in the safe zone and push your heat tolerance to the limit with zero collateral damage
FAQs
How does sauna affect my fertility?
Sperm cells begin to become unviable from prolonged exposure to temperatures above 99°F (37°C).
This is a massive issue during sauna sessions when your internal body temperature can reach as high as 106°F (40°C).
Studies have shown that regular sauna sessions (2+ a week) can significantly impair sperm count and concentration, taking months of avoiding heat for levels to return to normal.
How many cool packs come with my order?
Each pair of briefs comes with 2 freezable cool packs.
How do I keep the cool packs cold if I go to work/gym before using them?
We recommend keeping the cool packs in a thermally insulated bag with ice to keep them cold when you aren't using them immediately.
How do these shorts protect my fertility?
SaunaArmor™ Briefs creates a localized cooling barrier. The gel pack keeps your testicles within a safe physiological temperature range (~35°C) while the rest of your body gets the full benefits of the heat.
How long does the protection last?
The cool pack is designed to stay cold for the duration of your typical sauna session roughly 30 mins. Even once the cool pack has thawed, it provides a layer of thermal insulation which helps prevents your testicles from overheating.
Can I wear them into a cold plunge?
Yes, it is ideal to continue wearing the SaunaArmor™ Briefs while cold plunging as it can re-cool a thawed cooling pack.
How do I prep the cool pack?
Freeze it for 1-2 hours before use.
What materials are the briefs made of?
100% Cotton Body
Cotton/Spandex Waistband
How do I wash them?
Remove the gel pack. Machine wash cold. Hang dry or tumble dry low.
Do you ship worldwide?
Yes we ship most places! Your package will be sent out within 3 business days and may take between 8-15 business days to arrive depending on your shipment address.

Matthew S. May 2026Verified BuyerI always wanted to share a quick testimonial that you are welcome to add to your websiteMy wife and I have been trying to get pregnant and after receiving poor motility results I underwent a varicocelectomy and started religiously using these briefs with the ice packs to cool my boys down. Well, we just got my recent test results back showing remarkable improvement and we are now able to receive fertility treatment! We are certain these cooling briefs have played a big part and we're so thankful!SaunaArmor™ Cooling Briefs 100% Cotton Was this helpful? 0 0

Elias M. NOV 2025Verified BuyerFinally hit the 20-minute markI’ve been trying to extend my sauna sessions for the HGH benefits, but I always bailed around minute 15 because of the heat down there. First time wearing these, I sat for 22 minutes straight without even looking at the clock. The cooling effect is subtle but lasts the whole time.
