Mtwarden, how is the avail working out for you?
Excellent

I racked up a bunch of pretty high mile days- about 10 days total, ranging from 12-18 miles (with lots of vert!)- very comfortable pack.
Plenty of room for a long day out- I carried some shelter bits just in case- a lwt Climashield quilt, ccf pad and lwt bivy, along with a fleece mid-layer, syn insulated jacket, fleece balaclava & mittens, 1.5 liters of water, lunch and snacks; in the lower inner pocket- my kill kit, the upper- first aid kit, headlamp, fire kit, tp, etc
I also carried a small spotter (Razor 11-33x50) in the pack and a light tripod lashed to the side
pack weighed right at 25 lbs and was comfortable enough you forgot it was on
I never got the chance to mate to my Krux frame (was sure hoping I would!

)
I will probably add a couple of pockets to the waist belt and and a bottle holder on the side- should probably come with those imo
I'm headed out tomorrow backcountry skiing with it
in it's natural environment
