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.

Lightweight and carries a lot of stuff!
Very nice, lightweight backpack. Material is thin but backpack is sturdy. We took these to Disney to use to carry our purchases & necessities. These bags look small but they hold a LOT of stuff. We had ours packed full. It’s nice that it comes in a little bag that you can throw in another bag so you have extra room for carrying your things. Definitely recommend…especially for vacation.

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.

Exactly what you are looking for
I got this to have a small back pack when on vacation and it was perfect for that purpose. It is very light but durable. Big enough to have my extra shoes or flip flops, water bottles, bug spray, wallets phones, sun screen, etc. the straps were durable to hold all those things and comfortable to wear it for couple hours. I didn’t intentionally put it under water so I don’t know how water proof it is but it seems good enough. I was more worried about which size to get and I’d recommend to just go size up. Might as well get a bigger size and not fill it all the way. The color was exactly how I expected also. I recommend.

Light, versatile & ample
Got it for an overseas trip & it was great! Weighs nothing & can hold a lot in its 2 main compartments. The smaller one was big enough for readily available & accessible essentials. The larger one can expand purchases - like a wearable plastic shopping bag. There are also 2 easily accessible compartments for folding umbrella and water bottle that are ample & well fitted. The empty pack wadded so it can easily fit anywhere in a carry on or used at the airport for last minute purchases. We were in Japan so weren't as concerned of personal security issues. Can't comment on its durability for long term or heavy use but it was perfect for this & the tropical print blended in well. Often forgot it was even on.

If a daypack is truly what you're looking for, look no further.
For what this bag is -- a daypack that is extremely thin and light, and rolls up into a fist-sized bundle -- it's been satisfactory in almost every way. I have been using it for about 1 year and 8 months, and it has not failed me. | Pros: | - LOW WEIGHT, VERY COMPRESSIBLE: rolled up, I can fit it in the back pocket of a pair of men's jeans (snug, but fully possible), go in a store without raising concerns about shoplifting, and use it for my purchases when I leave. My friends have laughed at how insubstantial it looks when it's empty, and I think that reflects positively on this aspect of the bag. When I say the material is thin and light, I mean that it's between the thickness of a single-use grocery bag and a reusable plastic grocery bag. Or between a kitchen trash bag and a thick outdoor trash bag. - HUGE VOLUME, SPACIOUS: traveling long-term, I lived comfortably for a month on what I could fit in this bag. I managed to fit a laptop and charger, a small binder (~ 6.5" x 9"), two pairs of jeans, three shirts, several pairs of socks and underwear, and a toiletry bag in the main compartment; in the secondary compartment and side pockets, I fit a kindle, phone charger, power bank, a light for video calls, and several other small items. Was it absolutely stuffed? Yes. Has it burst on me when packed like that? Not so far. Am I confident that it won't burst? Not 100%. - IDEAL FOR AIR TRAVEL: this bag is literally the exact maximum size and has exactly the form factor to fit under a standard plane seat in coach on an airplane in the United States. I traveled with it when packing light, stress free. When it was absolutely stuffed as much as the bag could handle, I worried it wouldn't fit, but it did. - SUFFICIENT ORGANIZATION: okay, it is ~wild~ what the side pockets can fit. I've stuffed a pair of high-top Vans sneakers in one side pocket without issue. Between the side pockets, secondary compartment, and the little bag that's tethered inside (intended to store it when it's rolled up), I've been satisfied with the way I can organize items. I don't think I'd find more compartments/pockets useful. - WATER RESISTANT (sort of): enough for that to not be false advertising. Not amazing, but I honestly doubt a manufacturer could achieve much better with fabric this thin other than maybe its durability (see below) - MINIMAL ODOR: I don't recall this bag having a significant odor (new, plastic-y) when it came. - VALUE: that $27 USD has gone a long, long way. | Cons*: | * I think these are mostly drawbacks of daypacks in general, rather than this bag in particular. - UNCOMFORTABLE WHEN HEAVY: the shoulder straps have very little padding (if they did, it couldn't roll up as small), so if I pack enough stuff in it to really weigh it down, it digs into my shoulders and becomes uncomfortable after 20 minutes or so. If this is a concern for you, you could consider bringing two small pieces of fabric (like washcloths) to fold up for padding. Otherwise, I'd recommend you start looking at proper backpacks, not daypacks. - ZIPPERS SNAG EASILY: this is how I ruined the daypack I had before this one. If you are fast and reckless when opening the zipper and especially when closing it, the material is so thin that it easily gets caught, which can lead to zipper misalignment. It's happened a few times now, but thankfully I've managed to recover so far. - INSIDE WEARS AWAY: after a few months, the inner surface started deteriorating. I suspect this decreases the water resistance. The photo I've added is of the bag inside-out after 20 months; you can see the black areas where the coating has worn away. NOTE: this is the only aspect of the bag that I can imagine competitors doing better on. Like I said, most of the bag's problems are problems with daypacks in general, so I give it 5 stars. When it breaks -- all good things must come to an end, after all -- I will almost certainly just buy another one.

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.

Nice lightweight bag, surprisingly durable
Bought these as a daypack for my family in a recent vacation. They worked great and are surprisingly durable considering how lightweight they are. They hold plenty of supplies for a day trip. We had snacks, drinks, sunscreen, light jackets, hats and everything fit nicely. The orange color is great so they stand out in a crowd. My only reservation is the zipper seems like it may not last very long, and doesn’t open very big—it barely extends past the top corners of the bag, so bulky items may be difficult to squeeze in through the opening. But if you have bulky items, you may need a bigger bag anyway.
