Perfect Travel Bag
Absolutely what I was looking for - a travel day pack. Packs super small, super lightweight, yet strong and large volume. I’ve been biking around cities I’m visiting, and it’s working perfectly. I opted for the orange one, which adds a high vis pop of color to improve my road safety while biking. Also I love that the water bottle pockets are tall/deep enough to securely hold a liter of water. When I travel, I need to at least carry 1 liter of water with me. It does so securely. The smaller pocket is still pretty big, so I can throw in my wallet and phone and keys and passes and a map and my watercolor set. Like the odds and ends. Big pocket is for my sweater, etc. big items. Truly perfect all around.

Words can't express how phenomenal this bag is
I took this bag on my 2024 Camino de Santiago francés pilgrimage. It is among my top 5 best items that I brought with me. It is so phenomenally well designed that whoever designed it deserves an award. Seriously. I have the 22l version. Ok, huge main compartment. I can fit every clothing item on me in it with room to spare. Then, the front pocket on it - incredible. Skinny, and tall - easily holds every small item I have with tons of room to spare, and because it's narrow the items stay wonderfully organized. It's arguably my favorite feature of this pack, this skinny front pocket. The side water bottle pockets are also massive and roomy, but tapered and tall so I never had anything fall out, not even close. I fit 2 1.5L essential water bottles roughly a foot tall, and the pockets hold them incredibly. To top it off, this packs down to the size of my first, and weighs next to nothing. I consider a daybag at an essential item when backpacking around europe, and this disappears in my main pack, unlike any other bag I've brought. I forget it's there entirely. Is it the most durable in the world? No. I never had anything worse than one tiny tear in the bottom, the width of a dime. But I could see someone destroying this pretty easy. Durability is not the point of it though. All of this, and I paid like $14 used? The osprey version is like 6 times the price and far inferior in design. I will take this with me everywhere! Five stars all around.

Great daypack you can fit back into its bag.
This is a perfect bag for travel, home whatever. Its good for a daypack, with lighter loads. Tough and durable, and yes..you can fold it back into its carry bag. Hold two water bottles.

Good backpack
I bought this for my husband for his daytime hiking adventures. He likes how compact it is when he is not using it. It is a good size and actually hold a lot of stuff when he is hiking. It is lightweight and comfortable. He can use it during all seasons and even during a light rain. He has not tried it during a heavy downpour yet. We would buy this again if needed.

Excellent for travel
I bought the 24L in teal for a trip to Puerto Rico. For the trip I took a carry-on suitcase and a large backpack for my laptop and other items. I got this packable backpack as it is small, would not take up room in my luggage, and would be better for day-tripping around the island and to beaches than the large, heavy-duty backpack. It worked out great! I was able to carry a change of clothes, hat, raincoat (on questionable days), towel, suntan lotion, and water bottle and everything fit with no effort. At the end of my trip I left it with a traveling companion who was traveling longer and who realized how useful (and packable) it would be. I love that it has two side pockets for water bottles (some of the other packable bags I looked at did not have pockets for water bottles). I also like the two zipper compartments - the main one and a smaller one on the front. The zippers are strong and smooth and the second compartment enabled me to keep smaller items separate and more easily accessible. As others have noted, the straps are thin, but as I was not carrying anything heavy I had no issue and found the bag comfortable to carry throughout the day. Since it is thin, light, and unstructured I would not carry something in it that needs cushioning, such as a laptop. I was pleasantly surprised at how great this packable backpack is and how useful it was on my trip. I travel often and will definitely carry it with me from now on.

Don't under estimate this little item!
Great for any trip. Light weight. Recommended for a recent hiking trip (TMB) we took. I used it to carry my personal items to the shower(staying in huts) . When not in use easy to store. My husband even ordered and used one. We are home from our trip and he said the bag was a life saver.

Very solid for an ultralight, packable day pack.
Compact and well made. This stores in a very small size which is great for traveling or outings that may need a daypack. It is lightweight material but is well constructed. Don’t think you can’t tear or break it. Respect it for what it is. The zippers are very smooth, 2 water bottle pockets are generous and stretchy. The straps are basic but sufficient for intended use. This is not for carrying heavy loads. It worked perfectly for me on an 8 day trip to the USVI. It was used daily and carried dry clothes, snorkel and mask, microfiber towel, snacks, personal items, sunscreen, waterproof diving case for phone, GoPro, and a 24 oz water bottle. With a full load, wear it with both straps to distribute the weight. I would recommend this and may purchase another as a gift.

Mochila muy práctica
Esta mochila es muy práctica tanto para ir a caminar como para realizar compras. Es muy ligera y fuerte. Además es muy práctica porque la bolsa para guardar la mochila está unida, así que no perderás nunca esta pequeña bolsa.

Recipient quite pleased with item - although it seems rather smaller than described in both product details and reviews.
