Just guesses on my part, but having had some REI camping shorts in what looks like the same material and similar construction, I imagine they have foregone pleats in order for it to dry quickly and pack smaller. Their camping shorts and pants are all made of a thin synthetic which packs incredibly small and drys very quickly. I shop REI fairly often, but I've never seen the likes on the racks. Would be interested in seeing one on somebody to see how it looks. Anyone actually have one?
