These are beautifully constructed, but unfortunately they are totally visible-butt-crack knickers, quite see through, which is pretty much a dealbreaker for me. It's a bummer because they otherwise look great. I recommend spending the extra $20 for the the Garneau neo power airzone, which in my opinion are better for cool weather anyway. I finally retired some older Airzone knickers after 5 years, and they are *very* durable and never became translucent.
