Not Antarica Down There, But Close
I bought these because the looked like they had a good waistband that wouldn't roll (I'm built a bit more like the founder of this company than the models). Also, I run hot down there and it's hot where I live - brutal combo. I'm pleased to say that when I reached down to to grab a handful and check the temperature, it was drastically cooler than I had been in cotton undies or performance sport undies (think swoosh). I wish that I'd had a digital thermometer to check the temp and compare, but my wife seemed unfortable with the idea that I'd use a cooking thermometer below the equator (whatever). I will be replacing all of my underwear with Step One! These perform as advertised!!!
