the only time I have a problem carrying is when I am wearing shorts with an elastic waistband or a bathing suit that can't support my full sized glocks. other than that I really have no problem carrying I just wear shirts that I don't tuck in
fortunately for me i don't have to be outside unless I chose to be and my remora has no problems with the heat/sweat and my horsehide little bear never gets too affected by sweat eitherMuch the same. I hate working outside & sweating as much as I do, my IWB crossbreed feels all icky after a few hours. I wear an undershirt, but that gets soaked too. But I deal with it. No other real problems carrying my G22.
