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: 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!

### ⭐⭐⭐⭐⭐ Versatile light weight collapsible back pack
*by J***. on January 21, 2026*

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.
