Don't sacrifice your manhood.
Health Hercules Cooling Sauna Briefs are purpose-built for men who use the sauna regularly and understand that heat management matters. Saunas offer powerful benefits for recovery and longevity, but prolonged heat exposure turns the groin into a heat trap - directly impacting comfort and key fertility markers over time.
That’s why we designed the first 100% cotton sauna briefs with a dedicated front cooling pouch. No synthetic fibres. No spandex. No direct skin contact. Just breathable, natural cotton paired with freezable cooling packs to help regulate temperature where it matters most. Your first set will include one non-toxic, BPA-free gel ice packs.
Heat where it helps. Protection where it matters.

Special gift
Why is 100% cotton better than others?
Most sauna shorts use 95% cotton with 5% elastane because it's cheaper and easier to mass produce. In a sauna, that choice matters. Synthetic stretch fibers trap heat, become slick and clingy when you sweat, and sit right on the most heat-sensitive area of your body. They're also plastic-based, which means they shed microfibers during wear and washing. 100% cotton stays breathable, feels natural in high heat, and keeps synthetic fibers out of the equation.

Frequently asked questions
When will I get my order?
We will work quickly to ship your order as soon as possible. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.
How does sauna heat affect comfort down there?
In a sauna, the groin area can trap heat because it's covered and close to the body. Many guys notice discomfort and a lingering warm feeling after extended sessions. Health Hercules briefs are designed to create a cooler micro-zone at the front so the heat feels more manageable while you're in there. This is comfort and temperature-management gear, not a medical device. If you have specific health concerns, please consult a healthcare professional.
How many cooling packs come with my order?
Every pair includes one cooling pack. However, we give out two FREE ice packs per first order of shorts. The idea is simple: one pack can be in use while the spare is kept in the freezer, cooler bag, or gym locker so you can swap between rounds.
Will the cooling pack feel too cold or burn my skin?
The cooling is designed to feel controlled, not extreme. Most people describe it as “normal temperature again” rather than an icy shock. If you are very sensitive to cold, let the pack temper for a minute after the freezer, or wear them for a minute outside the sauna to settle the feel before you step in
Can I wear the shorts into a cold plunge?
Yes, since they are 100% cotton. You can take them into a cold plunge if that is part of your routine. After plunging, rinse them in fresh water and dry them properly. If you are moving between sauna and plunge, a second pack is handy so you can swap based on what feels best.
Why not use elastane at all?
Most brands include elastane to keep shape and make manufacturing easier, especially around waistbands and tight-fitting panels. The tradeoff is that synthetic materials can trap heat and become slick when you sweat. With Health Hercules, the priority is breathability and comfort in extreme heat, so the fabric stays clean and simple—100% cotton for maximum comfort during sauna sessions.

Customer Reviews
Overall rating: 4.8 / 5 from 358 reviews.
Was very happy with how good they fit and how comfortable they are. Very practical design, and actually works to keep all the right things cool. I had been using a regular ice pack covered in a paper towel before this.. This product works much better!
Honestly surprised by how good these are. The cotton is soft but durable and they don't ride up in the heat. I do infrared sauna 3 times a week and these handle it perfectly. The ice packs are a bonus. Would buy again without hesitation.
Got these as a gift for my partner and he absolutely rates them. Says they're the most comfortable thing he's ever worn in the sauna. The fact they're completely synthetic free was a big selling point for us given the research on polyester and sperm health.
My physio actually recommended something like this when I told him we were trying for a baby and I use the sauna daily. Found Health Hercules through Google and haven't looked back. The shorts are proper quality and the ice packs are a smart touch. Exactly what I needed.
Really solid shorts. Took one star off because sizing runs slightly large but otherwise no complaints. The cotton is thick and comfortable and they handle the heat well. Wash and dry perfectly too. Would still recommend.
Sauna 5 days a week and these have been a game changer. Comfortable, durable and the cooling pouch is actually practical not just a gimmick. Had them for about 3 weeks now and no signs of wear at all. The cotton quality is legit.
End of week reset, 88c for 22 minutes, and the pack stayed square while I stretched and grabbed water. Fit feels supportive without being tight. It looks like normal underwear which I like. I will buy another pair.
Cold plunge then sauna and I usually tap out early. With these I finished the full round and it still felt normal. The material is smooth, the seams are clean, and the insert stayed flush. Solid purchase.
Travel week with a few sauna sessions and I threw these in the bag. No fuss, no shifting, and it stayed comfortable. After a couple of washes it kept the pocket flat and the fit did not loosen up. Easy to recommend.
Bought these for my husband after reading the research on heat and fertility. He was hesitant at first but now won't go to the sauna without them. The ice packs stay cold for a solid 20 minutes which is perfect for his sessions. Great product and fast shipping to Sydney.
After footy, I wanted something that stays put. The insert stayed aligned even when I walked around between rounds. Waistband is solid, fabric is not clingy, and the whole cut looks well finished. Worth it for recovery days.
These are the real deal. I've tried a few different sauna shorts from Amazon and they all had synthetic blends. These are properly 100% cotton and you can feel the difference immediately. Way more breathable and no weird chemical smell when they heat up. Already ordered a second pair.
Wore these through a 95 degree session yesterday and they were unreal. The cotton stays cool against the skin and the ice pack pouch actually works. My partner and I are trying to conceive so this was a no-brainer purchase. Genuinely impressed with the build quality too.
These cooling briefs are genuinely excellent. Really comfortable and the quality is top notch. I use them in my gym sauna after every session and they've never let me down.
