    Very nearly perfect!

    As an avid year round outrigger paddler, traditional underwear is really uncomfortable (if you know, you know). Purchased these to wear under winter tights that aren't conducive to going "Commando" and they are excellent! The waistband is comfortable, no ride up on the leg, the fabric is great for extended sweaty workouts in any weather. My one quibble? I'd love them to be about two inches shorter. A length between the 5 and 9 (perhaps 7?) would be my holy grail length (I'm 5'4"). These are nearly knee length, nothing wrong with that, but it's a little long.
