I live in the low, hot desert over here in Arizona. I don't have too many problems with the kilt being too hot. Part of this is metabolism, but the only issue seems to be with the shirt thickness and the overlapping part of the kilt on my waist holding in a little too much heat. there's other X Markers living out here that do have problems with the weight of their kilts, though. It's just different for each person I guess.
