The one area of my commuting wardrobe that still needs tweaking is the undergarment/shorts zone. My commute isn't really long enough to require bike shorts and I don't find them that comfortable anyways. I've tried bathing suits/board shorts which work ok but they're not ideal. Briefs/Boxer briefs under regular shorts don't work so well because the seams always run under my sit bones and become uncomfortable. I'm thinking about trying compression shorts under nylon mid length shorts. Anyone have any experience with a similar solution or have suggestions for brands?

Ps. I have a Brooks B-17 so it's not the saddle.
