I've tried a few different shorts and wanted to suggest one and not suggest a second one. My favorite are the Pearl Izumi Tour (I prefer sugar short). I ride in them for short and/or long rides and they work great.
The pair I would strongly suggest against are the Performance Bike Gel. I don't think it was the performance bike brand (haven't tried any of their other shorts), I think it was the gel part. I NEVER sweat down there and the gel made me sweat like a man and also actually rubbed off some of my skin, and well, you know what happens when you sweat and rub~~not fun. Especially when you are 20 miles out and have to ride back home. I threw those right in the garbage.
The reason I tried the gel is becuase my DH loved them. After he saw that I hated them, he tried the Pearl Izumi Tour shorts that I adored and he never looked back. He threw away all his gels and switched. Haha! the wife was finally right about something related to cylcing, woohoo!!!
The moral of the story, I like the Pearl Izumi Tour sugar shorts, but even more, you are going to have to try different ones until you find the one that fits you the best.
Good luck short shopping!!!
