DUG, ain't never gonna happen with food and water, but if I can hit the trail on the 1st Whitney day with 25 pounds I'll be a happy camper. The cool thing about the Flash is that on summit day I can strip out the internal frame and have a super-lightweight daypack for just the essentials. I'm sure the marmots will be great caretakers of what I leave behind at Trail Camp . . .
I'll never be in the same UL class as Steve and Brett - I love my Quarterdome UL too much, and a filter is a must for me - but I don't think I've ever hit the trail for an overnighter with a base weight that low. This Flash is easily two pounds ligher than my old Kelty, but holds a lot more. Also, the NeoAir mattress might as well be a bag of feathers.
