I've been trying different types of underwear to find the most comfortable ones: briefs, boy shorts, hipsters, etc...these win hands down. Very comfortable, don't ride up, made of smooth, breathable cotton that's a good thickness, not flimsy; no thigh chafing or rubbing, and no panty lines! I'm gradually replacing all my panties with these.

Prices vary a lot between colors, so check all of them for bargains!

Be sure to check the size charts before ordering; if you use their guidelines they'll fit perfectly, but if you use your wishful thinking...not so much. ;-)
