On a more positive note. I just purchased a Tough Traveler carrier. MUCH better! I just took it this weekend, up Killington, Abraham, and to Lye Brook Falls. ~20 miles over 3 days. I love the new pack. I think my son likes it better too. Its good because he can't slouch left or right as much in it, because the head pads prevent that. Furthermore, his weight is put right up against my back, and the attached storage compartment is also right up against me.
Most importantly, I have no bruises, which wasnt the case after 2 hikes with Kelty's offering. Did I mention it only weighs 4.25 lb! The kelty was 8lb, and that didnt even include a pack for underneath. The pack has enough storage for more then a few items.
My only complaint is the buckle system for the shoulder straps could be improved. On ascents when you are leaning over, the buckles rub against your backbone a bit, but its not really that uncomfortable.
I highly recommend this pack.
