about the only negatives i can say about this underwear is they cost too much, and there is no fly. they are super comfortable. they dry very quickly when rinsed out, so they're ready to go again in hours. they are super light and very form fitting. being so light may cut both ways, i can't speak to durability yet because they are new, but they seem well made. i've never owned an arcteryx product that wasn't well made. even at this cost, i bought an extra pair. very satisfied.
