I read about the links between cycling, heat and sperm health. Decided to try these out - can definitely feel the cooling. The boxers are comfy and I don't feel the pouch on rides. Put my mind at ease, thanks!
Boxers feel GREAT, I bought seven and use them in rotation on my commutes. Easy to use and definitely feel cooler down there. Great product guys! :)

The Science
You've chased every watt. Carbon wheels, aero helmet,
a position dialled in over winter. All for gains of single percentages.
Here's the one you've been sitting on - literally.
Boston University (Wise et al., 2011) tracked 2,200+ men. Those cycling 5+ hours a week were roughly twice as likely to have low sperm concentration and motility as men who didn't.
Your testes need to run a few degrees cooler than the rest of you. The cause is simple: heat. And heat is a variable you can manage.
Cycling's one of the best things you can do and we're not about to give it up either. WattsBelow exists so you don't have to choose between the miles and managing the heat.
WattsBelow boxers just help you manage the one thing you've been ignoring. Natural cotton, a discreet cooling pouch, designed to support healthy scrotal temperature on rides. No bulky ice packs.
Kit up, cool down, ride.
FAQ's
How does the cooling work?
Simple. A slim gel pouch lives in the fridge. Before you ride, you slip it into the built-in zip pocket - the cotton body sits between the pack and your skin, so there's no cold shock, just cooling relief where it gets hot.
After your ride, pop it back in the fridge ready for next time. Keep one at home and one at work and there's always a cold one waiting.
Are they comfortable during rides and long rides?
Yes - these have been designed for exactly that purpose. We use them ourselves during rides, our founder is training for an Ironman and uses them - they're cyclist made, tried and tested. The cooling pouch is intentionally small and slim with the cotton body of the boxers providing a soft and comfortable barrier.
What are they made of?
WattsBelow Cooling Boxers are 95% natural cotton, 5% elastane.
The cotton does the heavy lifting - soft, breathable, no microplastics, no clammy synthetics. The 5% elastane is purely for fit, stretch and longevity, and it's a fraction of what you'll find in conventional underwear or cycling kit.
The average polyester boxer is 80–100% synthetic. The average cycling short is 100% synthetic. WattsBelow is 95% natural.

Keep chasing watts. Stop cooking your downstairs.
You've spent a fortune turning yourself into a faster rider. A pair of WattsBelow costs less than the kit that buys you a couple of watts - and it's the upgrade you'll actually feel every time it gets hot down there.
Natural cotton. A slim cooling pouch. Sleek enough to forget about.
Your next ride's coming - sort this before it does.
