I thought they were pretty crappy and not a value for $24. I found them to retain moisture everywhere and the chamois to be uncomfortable - they're hidden deep in the closet now, but I remember there being a seam or something right up the middle that didn't agree with me.
I bought whatever their recommended size was for a 36-37" waist and they were too big - not that bad but wide enough that the straps would come off my shoulders. Definitely would have gone a size down.
