Osprey Ultralight Collapsible Stuff Pack - Lightweight, Packable Travel Backpack — Extra Bag For Travel and Every Day — 18 L Capacity Daypack to Expand Luggage, Black

I travel frequently for both work and personal trips, and the Osprey Ultralight Collapsible Stuff Pack has quickly become one of those “why didn’t I buy this sooner?” travel essentials. It folds down incredibly small in my luggage, yet once unpacked it’s surprisingly comfortable and capable for day trips, airport carry-ons, excursions, and even grocery runs while traveling. What impressed me most is how lightweight it is without feeling flimsy. The material feels durable enough for real-world use, and the shoulder straps are far more comfortable than I expected from a pack this compact. I’ve carried water bottles, souvenirs, snacks, a light jacket, and electronics with no issues at all. The zippers are smooth, the stitching looks solid, and overall it feels like a thoughtfully designed product from a brand that understands travelers. This has become my go-to secondary bag for flights because it takes up almost no space in my suitcase but becomes incredibly useful once I arrive at my destination. It’s especially perfect for international travel, theme parks, hiking excursions, cruise ports, or simply keeping extra storage handy during long travel days. If I could change one thing, I wish it had one additional exterior pocket for quick-access items like sunglasses or a passport. The current design is streamlined and minimal, which many people will love, but one more small pocket would make it nearly perfect for travel organization. Overall, this is one of the smartest travel purchases I’ve made in a long time. Lightweight, practical, durable, and easy to pack — exactly what you want from an ultralight daypack.

Never disappointed with an Osprey product! Collapses super small. Easy to stow or attach to a larger bag and perfect for travel where you have to mind how much luggage to bring. The material is thin, but strong. Obviously there is no support with a bag like this but it is a solid trade off for weight and portability. There’s also limited organization and pockets but does have nice water bottle holders and small top zippered compartment. I brought this bag for a caving/tubing adventure in Puerto Rico. It was submerged and dragged through mud and tossed around on the back of a 4x4. Sure it was dirty after that, but a quick wash and it’s just like new. The most important addition’s to this bag compared to others are the adjustable chest strap and light breathable straps. I can tell you I have tested a bunch of similar bags and nothing comes close to the volume this holds, at the weight and compact size, with durable material and features. It’s a definite must have for any traveler. Also, Osprey offers the best warranty around, so if you ever do have an issue I am sure their customer service will take care of you.

The most amazing travel backpack of all time. Super portable. Very light and durable. Spacious yet not small enough for constant travel. Had this for 9 days in Italy across Rome, Florence, Perugia, and Assisi and I couldn’t be happier. The most perfect travel backpack ever.

I really adore this bag. I don’t use it much anymore as I opt for a sling most days but having this on me when traveling has been lovely. I could use it to carry my towel and accessories to the pool, walk and buy groceries, or just for outings. It’s small enough to just toss in my back pocket as a “just in case”. The straps can be a little hard for me to slide my arms into as a more larger framed person but it feels comfortable to wear and can survive a quick splash of water. The zippers are YKK and as durable and great to use as any of my other Osprey bags and the quick access pocket is great for things like keys or my wallet at the gym when traveling. The materials aren’t friendly to a washing machine though. So if you do intend to wash it, hand wash it in a sink or tub and let it soak to get rid of any smell. Overall, I’d gladly purchase this again. Osprey are so reliable from my experiences. I just wish they had an all black version without gray on the straps.

When ever I travel internationally, I don't check bags, only carryon. So I have a 34L day/backpack and a drawstring lap bag. I needed something smaller to carry around during city walks and day tours but bigger than my lap bag and this fills that gap. Packs away nicely in my buckle/waist pocket in my backpack. Only down side is that it's just a spineless bag and if you have awkward shaped items, it will look and feel awkward. Perfect for holding my puffy jackets for when I get hot. Top pocket is nice to hide wallet and passport in (doubles as the self packing pocket). Nice to have bottle side pockets for bottles and sunglasses and napkins and other random stuff.

Solid bag. Perfect for traveling. I usually stash this folded up in my luggage and use it as a day pack when I’m on a trip. Not as spacious as I would have hoped but it’s definitely doable. It’s lightweight and minimalistic in its design. Perfect for short day trips around town. Its build quality is great and zippers seem sturdy. I wish the material was a bit sturdier but so far I haven’t had any tears. It’s also a compromise to make it so light weight and packable!

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!

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.

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.

Det her är ingen riktig säck, fast en liten påse med en annan formsydd påse i sig.

Excelente material. Leve, resistente e com os compartimentos que eu preciso.

Came in good condition, can't wait to test the pack on my hikes

super plecak
