    • Very sturdy and comfortable to wear!
Color: 40l Purple Size: 40l Style: Daypack Backpacks
I carried this backpack loaded with drinks and rain gear weighing about 25 lbs through all 4 Disney parks. This back pack held up great! The waist belt and chest clip helped to distribute the weight and keep it comfortable! The side pockets are deep enough the the heavier water bottles did not fall out. I loved it and will be purchasing it again for my friends!! ... show more

    • Great, versatile pack for a great value
Color: 40l Blue Size: 40l Style: Daypack Backpacks
Well designed and constructed with many useful pockets and functions. Easy, multi-point adjustments allow comfortable fit. Room for a water bladder and everything else. The rain fly is a nice touch and easy to get on quickly. The pockets in the belt are the best, I can grab my phone for pictures without taking everything off. Such a great deal and has lasted through a few trips already with no issues. ... show more

    • Great backpack
Color: 40l Black Size: 40l Style: Daypack Backpacks
This backpack is awesome for my needs. I use it for hiking, going to the gym, and going to work. Its light-weight, durable, and extremely affordable. There are many compartments for all sorts of different items I need to carry, including a couple that I didnt even discover until months after purchase. The first one lasted me a few years before one or two of the zippers started acting up. At the price point, I was pretty happy about that lifespan. I was pleasantly surprised that, instead of being 100% identical, one of the compartments had an extra zipper that made that pocket so much more useful. Highly recommended from someone like me who puts a lot more hard-core miles on backpacks than the average person. ... show more

    • Not perfect, but a pretty good pack
Color: 40l Purple Size: 40l Style: Daypack Backpacks
Bought this for my Alaskan cruise-tour. Very comfortable, holds a lot, has an adequate amount of smaller/interior pockets. I found it easy to adjust the fit, and when I did get rained on a little, the water beaded and did not soak in. I had no cause to try out the rainfly, but waterproof was one of my main criteria for this pack, on this trip. Warning: if you have this pack pretty full, it can be challenging to get it under the seat in front of you. My two dislikes: 1) the zippers seem to catch fabric and stick fairly often; 2) my 32-oz metal water bottle, whose bottom is about the same area as my palm, is virtually impossible to return to the side pocket without removing my pack (or asking my husband to do it). I still give 4 stars due to the numerous ways to adjust straps and belt, roominess, and overall comfort of the pack. ... show more

    • Super Comfortable, Spacious, and Thoughtfully Designed!
Color: 40l Red Size: 40l Style: Daypack Backpacks
I always wear the backpack when my wife and I hike. I had been using an old nylon backpack for a while now (I think my son had used it for his college days), and when I put water, and other stuff, in it, the straps would get a little cheeky on my shoulders, but I never complained! My wife, though, surprised me with this new backpack, and I am so jazzed, as it is bigger, better, has more features (like the two built-in fanny packs, the two straps--one for the chest and one lower--the inside pocket for a camelpack (sp?), and the convenient ports for ear-bud wires). I am sure I am missing something, but, nevertheless, it is the very best and coolest backpack I have ever worn! She got me the red version, and it is as cool as a red Ferrari! ... show more

    • Great for the money
Color: 40l Green Size: 40l Style: Daypack Backpacks
First, this pack costs roughly $40, so keep that in mind. That said, I've hiked around 50 miles with it and I have to give it a lot of credit. It's comfortable, it's balanced, it holds everything I need it to hold and it seems to have everything all in one bag: - elastic cords down the front, which is great for keeping fleece or rain jacket handy; loops on each side for hiking poles with bungee straps to keep them secured; a very large pocket for a hydration bladder and 2 oversized webbed pockets on each side that hold larger water bottles ; zipper pockets on each side of the waist straps; it has an integrated rain cover; pads running vertically down the back that straddle your spine, and it has plenty of interior pockets for storage. I've hiked in all kinds of weather with it - sun, rain, snow, hot arid climates, hot humid climates, deserts, forests. Between Arizona, Wyoming, Montana, North Carolina, Florida...I've seen it all with this pack and it's taken all of quite well. All that said, this is NOT a high end, technical pack that I would take on a multi-day expedition. However, it you're doing an out-and-back and have to carry a lot of water and "stuff" to be prepared for whatever mother nature can and will throw at you in a day in the mountains, then I'd say this bag will do the trick and no break the bank. ... show more

    • Great hiking back packs
Color: 40l Green Size: 40l Style: Daypack Backpacks
Great product! I bought 4 of them for our family. We walked over 120 kilometers using these hiking bag packs as our main carry on. None of them give us any problems and no failures at all. I would buy them again.

    • I love this bag!
Color: 40l Purple Size: 40l Style: Daypack Backpacks
This backpack is an EXCELLENT value! I wish they came in a 30 or 35L option! The pocket configuration is better than any of the expensive name-brand backpacks I tried out! I used this bag for airplane travel, small hikes, and as a purse/diaper bag combo for daily life with kids for a a year, and then purchased a replacement! It fits fine under major airline seats, but on Southwest it was a stretch and it counted as an overhead item on small budget airlines like Avelo. I’m 5’2” and am able to get it to fit comfortably after wearing for a bit. The hip belt is so comfortable and the hip pockets ACTUALLY fit my iPhone 13 Pro in an Otterbox Defender case, and keep it easy to access without turning the pack around! 🙌🏻 I can’t quite reach the water bottle pockets to get them in and out while wearing, which is disappointing (but comparable to all the other brands I tried). The rain cover works great, and the bag was reasonably waterproof at first, but after about 6 months of frequent use, the waterproof membrane began peeling off inside. Another issue I had with the bag is that the Velcro strap designed to hold a hydration pack was catching on the hem around the zipper (which I didn’t realize), and tore the zipper. There was also some stitching on one of the shoulder straps that was beginning to come undone (I’ve probably been way overloading it). At first I was going to repair it, but then I accidentally left a banana peel in the pocket we use for trash and it got moldy. 🤢 So I just purchased my second backpack! First thing I did this time around was connect that Velcro strap to itself so it won’t tear the zipper again! ... show more
