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.

Definitely you want to purchase this. Exceeded expectations.
This is a great item. I’m so glad I purchased it trip. It was so lightweight and compact so easy to carry with me. And it held a ton of stuff. It felt light as a feather on my back. It was very secure. At one point I had a winter coat, a sweater, headphones, gloves, and a scarf in it, and it held all of that easily. This purchase should be a no-brainer and a welcome addition to any trip you take. To have something so compact and lightweight yet durable. I’m glad I purchased it.

Lightweight and packable, not super durable
I bought 3 of these for my family to use as pack able daypacks on a 14 day trip to Peru. They got lots of use, and were suitable for the purpose. They pack down super small and take up very little space in your luggage, but unpack large enough to fit a layer or two, a water bottle, and whatever you need for a day trip. They are very affordable and everyone got through the trip successfully. No one treated them super harshly but they ended up with the some tears in the fabric. Buy this for a trip or two, or occasional use and you won’t be disappointed. If you want something for more frequent use, heavier use, or want it to last a long time, spend the money on one of the big brands.

Durable and light weight
Becomes so incredibly small and weighs so little. This was the perfect day pack when we could drop our heavy packs. It also held a lot i was surprised how durable it was

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.

Perfect travel day use bag!
The 16L size bags are perfect for day use. Thin, lightweight and durable! My whole family has their own bags and we use them for travel in addition to our carry on luggage. We've used them for hiking, beach days and and theme parks. One large space to stuff a jacket, snacks, 2 side drink pouches and a small, but deep front zippered pocket for your meds, glasses or whatever. We also bought the 4 pack of quick dry towels and their beach towels. Love this brand and bags!

Perfect - LIGHT strong capacious, nothing cheap
Extremely impressed. Just got back from another (probably the 5th) moment of "let's go on a hike, oh shoot I don't have any backpack, oh wait - I have that mini one in my car bag!" It's strong, SO LIGHT, very very well set up - pull and zippers and pockets all in a good place. The zippers are great. I used it in the rain again, it gets wet eventually, but sheds water well and my Bible on the outside pocket was perfectly dry. You CAN STUFF this thing, it holds a lot! I have the large and medium I beleive, both are perfect. I have never run out of room. I've run demos for the wife showing how much I can keep putting in there! It's very comfortable for having no comfort features. Unbelievably light. I HAVE fried other mini backpacks. They were also impressive, 2 other ones (sorry, I don't remember them now - but that means I've tried this for over a year on multiple occasions) - but bulkier by far. This is JUST RIGHT. It is one of my possessions I LOVE. totally worth it if you can swing it. I didn't buy it for 2 months because of the higher price, but in the end it has brought me only delight. No tears, wearing out, stretching, no marking of the sipper rubber, the pulls are still perfect. And it packs up so tiny. People don't belive it. I can put two full sized Nalgene bottles on the sides, lots of snacks, way more knives than you're thinking of, books, and clothes in there. It just keeps stuffing. And I don't feel sore or fatigued in a way I'd expect - it sits right on my shoulders and distributes nicely. What can you expect from a bag that weighs less than a padded shoulder strap? We'll you get it and more. We'll done guys. Really nailed it, didn't cut corners, doesn't feel cheap in anyway. Very impressed. Holds a lot of weight. I don't love how easily things poke through to my back, but put a peice of cloth in there and it's fine. Very very thin material.

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.
