I am very careful to stay hydrated so my urine doesn't become too concentrated and smellier. I also change regularly, wipe down with scented wipes and shower daily, so thankfully I've really never noticed much of an odor issue. I suppose on those occasions when I might smell, the plastic-backed diapers I wear and the plastic pants I wear over the diapers are helpful. I never use "cloth-like" diapers. I guess I figure that if the diaper is "breathable" and lets cool air in and hot air out, odors are probably going to go out with the hot air too!
