Surprisingly durable, roomy, and lightweight
I just returned from a two-week backpacking trip overseas. While I checked my 30L backpack, I needed a carryon bag that I could also cram into my backpack for the hiking portion. I also used this pack to carry essentials for a night on the town, while leaving my larger pack in the hostel/albergue. This Osprey pack was exactly what I needed. Packability: I didn't even bother folding this bag up; I just crammed it into the bottom of my pack, and it flattened down to nothing. I didn't even notice it was there--It took up next to no room, and it weights next to nothing. Durability: this pack is very tough for having such thin, lightweight material. It holds up to abrasion and dirt, and it is even somewhat water resistant. This is not a pack that you can rip on a tree branch, or poke a pen through if you have one in your pack. Comfort: The chest strap (which also has a built-in whistle) and the shoulder straps distribute the weight evenly. Since this is a packable pack, there is no cushioning. So if you were to fill this backpack with sharp rocks, you will feel every one of them. I did wear this pack around a lot, and it was very comfortable to do so for several hours at a time. Capacity: I did worry that the airline would lose my checked hiking pack with all of my gear, so I filled this pack with a lot of stuff for the airplane, just in case. It fit a full change of clothes, a raincoat, microfiber towel, all my toiletries, an international AC adapter, two external batteries, cords, an iPhone and iPad mini, and half a dozen charging cords. Not to mention some snacks. And there is a water bottle holder on each side of the pack. I was able to fit a 1-liter Nalgene bottle in each of these. This is going to be my go-to backpack for this kind of travel for a long time.

Perfect day bag
Perfect day bag for traveling! I didn't know I could like a bag so much - but this thing is awesome. Holds a ton, has a couple different pockets, and folds up super small when you're not using it. Highly recommend!

fantastic size, weight, features, value. replaces a sling with a nicer form factor for a daypack
Fantastic ultralight backpack for hiking or as a daypack at your destination when traveling as a tourist. After using a sling bag for a while, I found two problems with it: 1. not quite big enough for bulkier items like a puffer jacket 2. ergonomics aren't so good for carrying more than one water bottle or drink. The sling feels better for specific cases like riding the subway and keeping the bag in front for security and to not bump others. But this ultralight backpack is overall going to better when traveling (mainly on vacation) and you need a daypack to carry only a few items around all day (sunglasses, sunscreen, phone charger, rain jacket, medicines, water bottle, etc.). The Osprey Ultralight Stuff Pack is perfect for reducing the size and weight - only 5.3oz and can stuff into its own pocket in a size about the same as an orange. It barely takes up any weight and space in your travel bags. Has a little key leash and some loops to attach other items. Bought it on sale so its value is tremendous. I like the neutral black color, but part of me wanted the bright orange color (which was not on sale at the time). I think this pack will be perfect for a day hike, on vacation, at theme parks, as an extra bag for a personal item on a plane in case you bought some souvenirs you want to bring home, and various other similar use cases. Definitely recommend this pack.

Great little packable backpack for travel
Great little packable backpack. Took this on a trip to St Croix and it worked great for carrying items from rental car to the beach, sometimes requiring over a mile hike to get to the secluded beach. Was able to carry two medium sized beach towels, a drone along with it's controller and a JBL bluetooth speaker. It was comfortable as long as I had the towels on the side resting against my back. When traveling, I have a nice, sturdy Osprey backpack for carrying my laptop, ipad, and a bunch of other stuff. However, I don't want to use it for hiking when I get to a destination and this one worked perfectly for my situation, and I anticipate using it for trips like this for years to come. Best of all, it was easy to re-pack it back into the compact form!

Nice no frills lightweight/could use some tweaks/is not very water repellant/45 is kinda high
This backpack is wonderfully light and durable. I love the top pocket for stashing items you want to get to quickly. I have taken it hiking and also used it as a personal item carryon. It holds a lot! It's very packable. Zippers seem sturdy. Straps are adequately padded for day hiking. I would give it 5 stars but for a few drawbacks. The features and specs say the item is water repellant. It started raining while I was hiking and everything in my bag got drenched. Not sure how it would hold up in light rain, but in a downpour, it did nothing to keep my items dry. The bag features a sternum strap. Would love for them to add a hip strap! I feel like $45 is a bit high for this bag, but would be well worth it if the bag were waterproof and had a hip strap.

Versatile light weight collapsible back pack
My go to when traveling. Collapsible, it's easy to carry. Large enough for day hikes, (though doesn't have any back padding). I use it as my under the seat carry on when flying. Quick trip to grocery store, farmer market.

Compact, well made and easy to use
Got this for my boyfriend for when he travels. He enjoys walking around whatever city he is in and this gives him the option to have a bag if he decides to buy things. The quality seems good and that it will last. He did have trouble trying to figure out how to fold it back up, but I did it in a out 5 seconds when he showed me he couldn't get it. That is pretty easy.

Value
I love this great little pack. So light weight and easy to carry when not in use. Went to Italy for a month and it was perfect for your impromptu shopping trips. It’s more bang for the buck as it holds way more than it looks. Along with comfortable on the shoulders. Easy to zip to get in and out of and withstand every day use.

This pack is the right size and very useful! Nice that it folds into its own pocket but ever since it arrived it's being used.

Der Osprey Ultralight Stuff Pack ist eigentlich ein genialer kleiner Rucksack, der sich problemlos in der Hosentasche verstauen lässt. Er ist super praktisch für Ausflüge oder als zusätzlicher Rucksack auf Reisen, da er extrem leicht und kompakt ist. Praktikabilität und Design: Der Rucksack ist wirklich durchdacht und bietet ausreichend Platz für das Wesentliche. Er lässt sich schnell verstauen und nimmt kaum Platz weg, wenn er nicht gebraucht wird. Die Idee, einen so leichten und kompakten Rucksack dabei zu haben, ist wirklich top. Qualität und Haltbarkeit: Leider hatte ich nach dem ersten Gebrauch schon ein Loch am Boden des Rucksacks. Ob ich es selbst verursacht habe oder es von Anfang an einen Mangel gab, kann ich nicht sagen, aber für mich war die Haltbarkeit enttäuschend. Der Rucksack scheint mir insgesamt etwas zu empfindlich, besonders bei intensiver Nutzung. Fazit: Der Osprey Ultralight Stuff Pack ist wirklich praktisch und für leichte, schnelle Ausflüge oder als Notfall-Rucksack gut geeignet. Allerdings hat mich die Empfindlichkeit des Materials enttäuscht, weshalb ich ihn trotz seiner tollen Praktikabilität nicht wieder kaufen würde. Insgesamt gebe ich 4 Sterne, da er für den praktischen Teil durchaus gut ist, aber die Haltbarkeit lässt zu wünschen übrig.

Buen material, aguanta mucho peso para lo fina que es y añadir que es muy cómoda de llevar. Un acierto para llevarla de viaje como un segundo bolso para completar el equipaje; no ocupa nada. No tiene acolchados y con elementos con puntas podría resultar incómoda, pero está claro que no está hecha para llevar ordenadores, cargadores y cosas así.

I was initially skeptical about whether this bag would be able to accommodate all my daily essentials during my trip. However, I was pleasantly surprised by its capacity and practicality. The size proved to be just right—it held my water bottle, a light jacket, and a few personal items with ease. One of the standout features is its water-resistant material, which provided added peace of mind during our visit to the waterfalls. Additionally, the bag is impressively lightweight yet sturdy, making it comfortable to carry throughout the day without compromising durability. Overall, this was a great purchase that served me exceptionally well throughout my entire trip. I highly recommend it for anyone seeking a reliable and compact travel companion.
