I wear only knickers — well, I do wear something on top, but you know what I mean. I never wear shorts because of the sausage effect on my thighs. I absolutely LOVE knickers because they're so darn comfortable, and I wear them all throughout the summer and winter, too. If I need more warmth in cooler temps, I simply wear a lightweight synthetic biking pant over the knickers. I've tried a few different brands of knickers, but so far I like Pearl Izumi and Boure. Some day, after I've dropped about 60 pounds, I'll try a pair of Assos.
