Found a way to carry, in this pack, everything but food and water, keeping the weight under 5 lbs. How? Purchase 3 toiletry organizers (10 x 4 x 5.5 each) from another company that also makes bags and attached them to my leather belt in my nylon short/pants using the wide loop end for the belt to go through on one end and slide my belt inside the carabiner which is attached to the small loop on the other end. The 2 side ones each carry a 1 liter water bladder and the back one the food. Since these bags weigh in at 1.6 ounces each and the pack weighs in at 3.2 ounces, you are talking 8 ounces and around very low $100s to carry gear for a 4 day / 3 night AT Summer Hike. The bag itself is missing a couple of items, a second pocket, for those overnight trips where you just want to carry 2 water bottles and a chest strap, which I added (weighs 0.7 oz/ 20 grams) to allow adjustments for each body type or allow to change width for . Each of the 2 biners weighs in at .1 oz or 2.8 grams. The bag material is very strong for its light weight. The inside pocket at the top is handy for small items that can get lost. If Osprey adds a second pocket and a chest strap, they would have the talk of the town at around 4 ounces. Otherwise, it does the job pretty well for this application.
