Customer Reviews Osprey Ultralight Stuff Pack

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.

This is an addendum to my prior review. I sewed a small loop to the back of the main compartment, so I could hang my Camelbak 3-liter hydration bag to it. I tried it and it worked well. Osprey may want to consider adding this feature. the pocket for a water bottle that the pack comes with is pretty loose. It's okay as long as you don't bend over. If you do the water bottle falls out readily. Otherwise, as I said before, I like this pack.

I like this pack. I got it recently for day hiking while backpack camping and used it for a number of hours one day. It does the job. It holds a lot and is comfortable. I took it rock scrambling up a desert canyon that was overgrown after a heavy rain season (Southern Cal.) I was sliding down boulders so the bottom of the pack may have dragged. Also, was getting caught on a lot of Cat Claw Acacia and other nasty desert foliage. The pack ended up with two small holes on the bottom of it. I think this was unusually brutal use and would not happen with normal use. So this is what tenacious tape is for, right?

Great platform where Osprey could add another side pocket and a sternum strap, keeping the weight under 5 ounces and the price increase by $10 and voila, you'll have a SUL pack ready to devour the competition.

disappointed when I got this...as it is dark green, definitely not gray. Will return.

Considered this as a daypack for short hikes. My concern was there was a pocket on one side, where I would put a water bottle. No pocket or place to attach another water bottle or anything else to balance the pack. My spine just ultra sensitive when pulled to one side, so may not be a problem for other people. Looks like great ultralight packable sack pack other than that.

It's an ok bag. I thought it would live up to its name but as someone who seasonally camps and goes on lite hikes and doesn't overpack i thought the quality would be a little better. I've had the bag for about a year and already there's a tear in the seams. Also it is rather difficult to pack it into its pouch. And the water bottle pouch is nice addition however not the most secure. For a budget packable bag I wouldn't buy unless it goes further on sale.
