High-heat exposure is proven to suppress sperm health starting from even a single sauna session. Once damaged, it can take multiple months to recover sperm count and quality with the counter resetting each time you sauna.
We don't think you should choose between recovery or male health. That's why we made SaunaArmor™. Our targeted Active Cooling Core™ protects your testicles so you can focus on enjoying the sauna with peace of mind.
Your gym shorts were made for workouts. HeatPure™ was made for the sauna.
When you’re sitting in a 200°F sauna, what you wear against your skin matters more than it does anywhere else.
That’s why SaunaArmor™ uses our HeatPure™ Cotton Body. A 100% premium cotton construction designed specifically for high-heat sauna sessions.
Most underwear and shorts rely on synthetic blends like polyester, nylon or elastane to add stretch and durability.
We took a different approach: keep the main body natural, breathable and comfortable while the Active Cooling Core™ handles targeted cooling where it matters most.
HeatPure™ Cotton Body gives you:
The Active Cooling Core™ delivers targeted cooling exactly where sauna heat hits hardest.
Slide in the frozen insert, keep your boys in the cool zone, and stay comfortable deeper into your session to reap the benefits.
The inserts are adjustable to sit beneath the testicles when you are seated.
Everyone has a slightly different body, especially when sitting down.
That's why we designed the Active Cooling Core™ to be loose enough to reposition for your comfort, but secure enough to not move around when you shift positions in the sauna.
From a simple problem in the sauna to a new standard for the people who return to it.
Our founders learned about the drawback to their favourite recovery routine. They began bringing ice packs and DIY setups with them to every sauna session. They quickly realized that this wasn't optimal.
Sauna Protocol was born and quickly went from idea to production with the launch of our first products.
Through trial, error and customer feedback we improved our product quality and made the switch to 100% cotton construction. Developing our HeatPure™ Cotton Body with our manufacturing partners.
We decided that we wanted to create more products for people who love to sauna as much as us and began development on creating new, thoughtful products for sauna lovers worldwide.
With a new direction in mind, we are working on creating products that customers have never seen or heard of before that will make their sauna sessions more beneficial and enjoyable.
Brand new products the world has never seen before launched?

I always wanted to share a quick testimonial that you are welcome to add to your website
“My 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!”

Finally hit the 20-minute mark
“I’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. Essential gear.”

Peace of mind for me and my wife
“My wife and I have been trying for a baby for a few months, and she was on my case about my post-workout sauna habit. I bought these to compromise. Honestly, I expected them to be uncomfortable, but they are great. The gel pack doesn't freeze your skin, just keeps things normal temperature. Wife is happy, I'm happy.”

Part of the daily kit now
“I don't go to the gym without my belt, and I don't go to the sauna without these shorts now. It’s weird how much more relaxing the heat is when you aren't constantly worrying about burning your junk. Fits surprisingly well too.”

Gift for my husband
“Got the 3-pack for my husband because he refuses to stop saunaing despite us planning for a family. He was skeptical at first but now he swears by them. He says it makes the session way more bearable.”

Comfortable, good cooling
“I was worried the pack would be too bulky, but you barely notice it when you're sitting down. The fabric creates a nice barrier so it’s not ice burn cold, just refreshing.”

Great for contrast therapy
“I do sauna/cold plunge cycles. These are great because I don't have to worry about the heat spikes. Can just keep the pack in if I want to jump in the plunge after.”

Better than the wet towel trick
“I used to sit on a cold wet towel or bring a bag of ice in. This is 100x better. Handsfree, doesnt drip everywhere, and the cooling pack fits perfectly in the pouch. The zipper feels high quality too”

Sizing advice
“I'm a 34 waist and the Medium fits perfectly. Snug enough to keep the pack in place but not too tight. Cooling lasts about 20 mins.”

Extended my session by 5 mins

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.
Each pair of briefs comes with 2 freezable cool packs.
We recommend keeping the cool packs in a thermally insulated bag with ice to keep them cold when you aren't using them immediately.
SaunaArmor™ Briefs creates a localized cooling barrier. The gel pack keeps your testicles within a safe physiological temperature range while the rest of your body gets the full benefits of the heat.
The cool pack is designed to stay cold for the duration of your typical sauna session, roughly 30 minutes. Even once the cool pack has thawed, it provides a layer of thermal insulation which helps prevent your testicles from overheating.
Yes, it is ideal to continue wearing the SaunaArmor™ Briefs while cold plunging as it can re-cool a thawed cooling pack.
Freeze it for 1–2 hours before use.
Body constructed from HeatPure™ 100% Cotton. YKK zippers. Waistband made from cotton/elastane blend. Each pair comes with 2× Freezable SaunaArmor™ Cooling Inserts. Inserts are made from woven nylon and contain a water/silica based gel (BPA Free & Non-Toxic).
