We worked with fertility doctors and the UK’s Channel4 to test the cooling power of Snowballs against boxers and regular briefs. Three men spent a day wearing each type of underwear, and then an infrared thermometer was aimed at their hot zones. The results:
Boxer-briefs: 31°C (87.8)
Traditional briefs: 27°C (80.6)
SNOWBALLS: 22°C (71.6°F)
The health benefits of “manly cooling” have been emerging for years, but now there’s even more proof that men who care about fertility should stop frying their swimmers and wear Snowballs to stay cool!
And in case you’re wondering about the comfort of cooling, here’s what our valiant test subject had to say: “I loved them. It felt like I was being gently caressed.”
