So last night I had the misfortune of being stuck unloading a truck where, even at night, the temp was almost 85 inside, but I was wearing these boxer briefs and they were absolutely wonderful! My lower body area was very cool still and dry, where I have had experience with other brands where at the end of the day I was soaked with sweat! The best part of these is how they fit and don't ride up and are very comfortable! It does take a little bit to get used to the separate pocket for the penis, but once you get used to it (which does not take long) you will wonder why you never had this before!
