I decided it was time for a new pair of biking shorts. I received a pair as a gift from a biking enthusiast boyfriend, way back in my college days, but this time I was buying my own. After trying on a thousand pairs, and polling my biker-chick friends on their favorite brands, I went with the Peal Izumi Ultrasensor Shorts ($95). They may be a little pricey, but the investment in keeping my backside comfy is certainly worth it. More than the padding, which they amply provide, these shorts are designed to wick. The padding and the fabric of the shorts both promote evaporation. Plus, since we are talking technology, I should add that the chamois (aka padding) contains silver fibers to provide some antimicrobial action by reducing bacteria naturally.
Most importantly these bike shorts are comfortable and flattering. They have a little leg gripper action at the bottom seam so the shorts don't ride up, but the gripping elastic is comfortable and doesn't dig into your legs. Another key feature, these shorts are machine washable, which is always important in workout wear since you are hopefully going to do some serious sweating while wearing them.
You can find them here.
