Lightweight, Compact, and Perfect for Exploring
The Osprey Ultralight 20L Dry Stuff Pack was incredibly useful while I was sightseeing. It’s amazingly lightweight and folds down into a small pouch, which made it easy to pack and carry until I needed it. Once unfolded, it has plenty of space for essentials like a water bottle, camera, snacks, and a light jacket. The straps are surprisingly comfortable for such a minimalist pack—no digging or slipping, even after hours of walking. The material feels durable, and the waterproof design gave me peace of mind when the weather turned unpredictable. Overall, it’s the perfect travel companion: compact, functional, and comfortable. I’m really glad I brought it along!

The pack to carry when you don’t even know if you’ll need a pack.
First of all, this is a small pack that is designed to be lightweight and packs into itself. It’s not intended to be the height of durability, though the fabric holds up well. Good zipper quality and function. Comfortable to wear if you don’t weigh it down too heavily. Several compartments, but as a small pack, don’t expect a full pack’s worth of versatility. It’s not padded extremely because again, its purpose is to be packed into itself and remain compact until you need it. Excellent choice for emergency essentials for a day hike. Very well made for what it’s intended to be. Good price for what you get, too.

Packable waterproof travel backpack!
Purchased this backpack for a trip to Iceland and I'm very happy with my purchase. Lightweight, durable, and packs up small! This backpack fits a lot. It has the typical dry pack closure that you roll down. Has two exterior side pockets that fit my water bottle perfectly and one front zip pocket. I'm only 5'3 so I was worried it would be too large for my shoulders but it worked out great and I was able to adjust the straps easily, depending on how full the pack was. The great thing with a soft pack is you can fit jackets, hats, gloves, extra socks and snacks, and it stays light! Easy to wipe clean and held up great on all our hikes, kayaking, and being thrown around.

Very nice day pack to pack in a suitcase for traveling
This is the first ultralight backpack I've ever bought, so I don't have anything to compare it to. I took it on a cruise as a day pack for excursions, and it is perfect for that. It folds/rolls up very small for packing in a suitcase, and it holds everything you need for a day out - water, hat, sunglasses, keys, raincoat. There is absolutely no inner structure, though, so don't carry a tablet or anything fragile. The shoulder straps are not padded, but they are wide and comfortable for what I was carrying. If closed as designed, it keeps the contents dry in wet conditions.

Great Travel Day Pack
I bought this pack to use with a small camera insert for Machu Picchu, as my camera pack was too large and didn't want to risk putting expensive camera gear in a public locker. I ended up using it nearly every day for the 3-week trip, and it held up well! Plenty of room for the insert, Nikon Z8 with 24-200 attached, and an extra lens (up to Z 100-400mm), plus extra batteries, power bank, cables, water bottle, and snacks with room to spare. The only negative is that in warm, humid/wet places, moisture from your back will seep inside and become trapped, so it becomes like a sauna. It does a good job of keeping rain out (rained for two hours at Machu Picchu), but for any extended wear outdoors, the bag contents will have a layer of dampness when you unpack and the bag will need to be flipped inside out to dry.

awesome day pack! great value for money too.
love it lots! super packable so when i went for a 3 week trip through europe, i tossed it in the luggage with little weight or size penalty. I used this as a day pack instead of my regular pacsafe which I use on the plane when i need to lug the tablets etc. it's light and waterproof so its just right for keeping your extra heavy stuff like your powerbank, umbrellas and snacks which wont fit in your pocket. word to the wise- dont put your wet umbrellas in the main pocket use the side pockets instead. wet stuff will of course stay wet inside the waterproof bag making everything else inside the bag soggy. - dont ask me why i know *rolls eyes* fortunately drying is a snap. just flip it over and dry it when you get home. caveat- although this is difficult to open by thieves and the like due to the roll and snap top, i wouldn't really call this bag "slash proof" so keep your passport and other valuables elsewhere just in case yeah?

Best lightweight waterproof daypack of all time??
Yes indeed it is. I was looking for a lightweight, waterproof 15-20L pack for short bikepacking trips, and a daypack for all of life’s less exciting adventures. This checks all the boxes, including some that weren’t even on my list. It’s that cool. When it arrived I first had to test its alleged waterproofness, and I did with vigor! It really truly is waterproof even though it’s incredibly thin, lightweight and packable. Next it had to survive the rigors of being supportive while being stuffed to the max with overnight bikepacking gear whilst also maintaining a reasonable degree of comfort while wearing on a bike for several hours with 10+ pounds in it. I’m here to tell you, it did that too. I added a small foam insert that slid in the back to keep a modicum of rigidity under a poofy load which certainly aided in my success in this scenario. In regular day to day activities it excelled as well, from easy hikes/picnics with kids to daily stuff sack for extra layers on the go to grocery store shopping pack and more! I plan to use this as my Grand Canyon R2R2R overnight pack later this fall as well, I think this featherweight, Swiss Army knife of packs can pull off just about anything. Best gift ever for your outdoor enthusiast partner, friend etc. I’m not a paid sponsor of Osprey but am open to the idea of it….Osprey…are you reading this?? I’ve had their backing packs and hydration packs for years and this is by far the most exciting purchase from them to date. Cheers

Not very comfortable for big and tall
Its pretty expensive so I expected perfection. The front shoulders clip isn't adjustable so if you you want the blood to run to your arms you have to give up your airflow cause the strap is on your neck. Except that it's a nice and practical backpack.

Comfortable to use
Appears to be well made and relatively strong. Be aware though that it looks very wrinkly and creased unless it’s fairly fully. The darker the colour the better it looks.

Lightweight, Practical, and Great for Travel
I’m a big Osprey fan, and this is my second packable Osprey backpack. I really like the 20L size, which is perfect for a day trip. The two side water bottle pockets are very useful, and I also appreciate that it is waterproof. The black color works well too, even for city breaks. One improvement would be an additional small zip pocket, ideally near the top. The outside pocket alone is not always enough, and sometimes it can be hard to find smaller items in it. Other than that, this is a must-have item on all of my trips, both leisure and business.

Práctica
Conos es osprey no me sorprende la calidad. Es muy práctica para viajar porque se hace pequeñita para poner en la maleta . Y una vez en destino la sacas para pasear libremente con ella. Es impermeable y no te preocupas si llueve. Súper ligera. El bolsillo exterior tiene un cierre impermeable . Tiene dos bolsitas laterales para poner agua o el mapa de la ciudad. Y como tiene cinta corredera no se te sale sin querer la botella de agua. Me gusta que tiene cinta de esternón para que sea más cómodo caminar o correr co ella. Súper ligera para pasear en la ciudad. Lo único que le pondría es un listón con gancho en la parte interna para enganchar o llaves o un pequeño monedero.

Lightweight and good quality
Very lightweight and useful as a day pack when you're out hiking or camping. Given how light and flimsy it is it's still quite robust and very comfortable to carry a few kilos of load. Waterproof. Used to great effect when day hiking mountains

Aanrader als opvouwbare rugzak
Makkelijk om in te pakken en groot genoeg om het noodzakelijke te dragen tijdens de vlucht en overnachtingen. Handig om boodschappen te doen en past goed in een handtas als extra item. Sterk, mooi vormgegeven, goede indeling en ruim voldoende als daypack. Als je het niet gebruikt, neemt het weinig ruimte in je backpack/koffer.
