Review: 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.
Review: 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!

### ⭐⭐⭐⭐⭐ Surprisingly durable, roomy, and lightweight
*by J***R on August 28, 2025*

### ⭐⭐⭐⭐⭐ Perfect day bag
*by S***R on February 14, 2026*

### ⭐⭐⭐⭐⭐ fantastic size, weight, features, value. replaces a sling with a nicer form factor for a daypack
*by A***R on February 5, 2026*

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.
