Osprey Ultralight Stuff Pack, 18L, Black, O/S

Excellent backpack. Packs very small, I have used to carry a decent load ( around 10kg) and the straps feel solid and comfortable which is especially surprising given that there is no padding. This backpack has no back padding, so be sure to pack soft items closer to your back or a long flat object for the most comfort. I use it when commuting by bike to carry shopping on the way home.

You are paying for the osprey price but the product itself is very nice and durable. The water pockets outside are deep which is unexpected for backpacks of the size. There is no fancy compartment system for the main backpack. So don’t expect to have a separating layer between your laptop. The nylon material feels very durable, so are the zips. The packing system feels slightly unintuitive at first with the direction of the bag that you’re supposed to pack it in at. But I’m assuming that after a few tries you’ll quickly get the hang of it. Bought this for my girlfriend, who needed to have a day trip bag, for her trip to Spain and couldn’t be more happy with it. Bought the bag with confidence knowing that it’s packed by Osprey lifetime guarantee.

Lightweight and nice quality bag, perfect to throw in a coat pocket or back pack to use as a daily when on a trip .

This little bag is amazing! Considering how small a parcel it folds up into, it holds everything you need for a day out. Ideal accompaniment to stuff into your luggage and use as a day bag whilst on holiday, or to use from home just for a day out. Amazingly lightweight, yet quite strong and sturdy. I did wonder whether I would be able to fold it back into the pouch again, considering how small it folds up but it actually was easier than I expected.

Useful from day one. I take it when I go for a small shop or just for a walk. Who knows if I find something or maybe just need to carry water bottle. The quality is very good. Very easy to open and roll back to the pouch version. I wear it attached to my bum bag, in case I need a larger capacity. It's my go to backoack for shopping. The size is perfect, fits plenty of stuff inside.

Osprey did a good job with this bag. It folds up small enough to put in a jacket pocket and is durable enough to be a rucksack. My experience with other packable rucksacks is that they are very useful but quite flimsy. By contrast, this one is solidly made and comfortable while only being slightly larger folded up than the others. I’ve comfortably carried six half litre glass bottles in it with no problem, which is something that would have been risky and uncomfortable to carry in my other packable rucksacks.

Very good, used as carry on on easy jet. Very light weight, worked well,

Bought this as an under seat flight bag and lightweight pack for sightseeing, as supplement to my main hiking pack. The capacity is very generous for the size, it's good quality, and folds up small when not in use; shoulder straps are well-designed (v light) and there's the same whistle as on the full size Osprey packs. However, the downside is that it has no structure, so it's not very comfortable to carry water bottle/umbrella or small heavy items like battery packs in the top compartment, when the main compartment is not full - drags down at the back and there's no strap to keep water bottles in place, just mesh pouches, so they are apt to fall out when you bend over or put the pack down. Not waterproof either - need to put contents in a plastic bag if you're out in the rain. For city use, I prefer a more structured small pack from another brand, with padding at the back, but this is useful if you need large capacity without weight for travel.
