Sounds almost too good to be true. Hopefully Kifaru is really on to something here that will change the market. To this point, it has been my experience that lightweight packs lack durability, comfort, or function. Being familiar with the Kifaru fabric used in their shelters, I would be somewhat reticent to have a pack with it, even double layered.
I look forward to you 24hourcampfire guys doing some additional "research". :-) If it turns out to be the real deal and lasts as long as a normal pack, it will be tough to pass up.
