My nipples bleed, I sweat, It’s hot (60 degrees) Bunch of pussies. Keep your shirt on. Nobody wants to see your disgusting bodies. Why don’t you take your split shorts as well?- their sweaty and hot. Lots of BS here. Elite marathon runners racing with their singlets on, but the average Let’s runner can’t wear it if it’s above 60 degrees. BShitters that’s what you are.
