I have a problem with cycling shorts not lasting. I'm not hard on them, I just ride in them. I have a pair of Garneau's, the seam down the pad inside started to rip (doesn't feel too good on the man berries), and they're wearing thin in the back part where I don't sit. I have a pair of Italia national shorts made by Castelli, and one of the seams in the back tore on those after about 5 months of riding. I expect a lasting product when I pay $45-$80 for something. I'm an average sized guy, and I wear shorts that fit me properly. Does anyone else have this problem, or could you direct me towards shorts that are known for their durability?
