I have PI Sugar Knickers and Sugar Shorts; they're good value for money, I think. They're short for me (I guess I have freakishly long femurs or PI runs short). The PI Ultrasensor shorts are amazing, I just got some and the fit is superior to the Sugars, more flattering, more muscle-hugging, better wicking. They're about 2X a much, too. (I went a little goofy in the heat, I guess )

I also have Cannondales but they're only 4 panel so the fit isn't as nice, the fabric is thinner and the chamois is...curious. They are good for riding the trainer in winter.

The PI shorts I bought in 1996 lasted 10 years. The chamois has finally reached "thin," but the fabric is good and there's only some minor hem unravelling at the left knee. They've not torn even when I hit the road--hard--earlier this month.

Good shorts are an investment, but I do recommend that you try them on if you can. Sizes are vary from manufacturer to manufacturer.
