None here, either, but based on the website specs and the reviews I've read, it would be #1 on my list should my current pack (Six Moon Designs Comet discontinued in 2006) decide to fall apart (no signs of that yet, so not likely I'll be trying the Kalais anytime soon).

Enthusiastic reviews of the Kalais are here and here. Somewhere on YouTube, Sgt. Rock, author of the first review, has a video, although it's rather dark.

My #2 choices would be the ULA Ohm 2.0 and perhaps whatever emerges from the new partnership of Ron Moak of SMD and Brian Frankle, former owner of ULA.

Whichever one I'd finally pick would, of course, depend on a try on and several hours' hiking around the house with all my gear plus a week's food and water, since pack fit is almost as individual as shoe fit. (Pika, I know you know this very well; I'm just throwing it in for the less experienced among us.)
