Does anyone have experience with the sizing of these pants? I went to world cup and tried on a size medium, but they felt tight around the butt and thighs and I did not have any pads on. The knee pads seemed to come up high on my knees also. But, with the size chart online, it says a medium should fit me as I wear a size 33" waist jean. The sizing chart on pbrack says a medium should be 32"-37" and a large should be 34"-39". The larges are also 2" longer in total length. Any suggestions???
