Okay, just got back from a 30 mile ride on a very warm, sticky day, and got caught in the rain. The Baleaf padded undershorts are comfortable, no complaints so far. Relieved the chafing I'd experienced in the perineum recently as the warm, humid weather set in. They're probably over-padded but who knows how much the foam will flatten with use. No idea yet on durability.
Regarding sizing, several Amazon reviewers said these run a bit small, so order the next larger size. I did and ordered the large rather than medium -- I'm 5'11", 165 lbs, 34" waist due to beer pudge. The large fits well.
