I'd look at the Badlands 2200.
Built in meat shelf.
Kevlar bar tacking at all of the stress points.
All seams are sealed and taped for the ultimate in water resistance.
Holds a 100oz water bladder.
It has a rear entrance that allows you to enter the main compartment of the pack without taking the pack off.
You could probably spend 2-3 night out and be very comfortable.
Not to mention the best Lifetime Unconditional Guarantee in the industry. If anything ever goes wrong with the pack,doesn't matter if it's your fault, they will fix or replace the pack at no cost. Doesn't matter if you bought it at a garage sale, they'll take care of you.
Hmm..I don't think I forgot anything.
I'd post a picture if I could figure out how.
