Great, versatile pack for a great value
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.

Very sturdy and comfortable to wear!
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!!

Super Comfortable, Spacious, and Thoughtfully Designed!
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!

Not perfect, but a pretty good pack
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.

Great for the money
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.

Great overnight sized backpack at a great price
I was very excited about this backpack as I needed a reasonably priced back pack sized between 2 of my hydration day packs and my full sized metal frame 65 liter backpack. I was looking for something that would easily carry a days load for camping (or long overnight hikes) and this fit the bill in terms of price and size (about 22 by 14 by 10 inches packed) . I was very impressed upon opening the package by the light weight yet durable fabric. It’s not ultra thick which saves weight but yet is perfect for the loads I’m carrying, which would typically be a full days change, a sleeping bag, battery pack, flashlights, some food, snacks and a hydration pack. You can easily secure hiking poles to this pack as well. A hydration pack is not included, but is not expected at this price point, I plan on using 1 or 2 from my other packs, depending on the trip. A zipped water resistant toiletry sized pack is included and is a nice touch. The backpack has 2 large zipped compartments, with the rear, larger compartment having the most padding and a large interior pocket. As a storage test, I packed 2 sleeping bags in this compartment (pictured). You could add some padded cargo (e.g. clothing, towel) to the front most pocket if carrying a laptop or tablet (which I don’t plan on for this pack) in the thinner front zipped pocket. The rear zipped compartment has separate holes for headphones or a charging cable and one for the tube of a hydration bladder. There is also a small zipped pocket on the top and one on the bottom containing the rain cover (which can also be used for storage). There are lots of straps and pockets on this pack, including one on each of the hip belts (which I love for phones, wallets and keys). There are also lots of loops, both plastic and fabric for carabiners and attachments. There are 2 large side pockets that would comfortably fit very large water bottles, both come with straps for securing the cargo in those pockets. There are 2 cargo loops which can be used for securing a jacket or smaller sleeping bag as pictured, I would opt for this to save interior space for clothing and other items. Overall, I think this backpack is an excellent value and looks like it will last me on the trail and at the campsite, I look forward to taking this out with me soon and will update once it’s been field tested.

Item comes as pictured
Bag is as pictured, quality seems good ( hav not packed the bag but have tested all the zips clips etc). Good amount of features at this price point, very happy with the purchase and delivery so far.

It feels different. Comfort and satisfies my need
It feels different immediately compared to my other travel backpack which does not have the waist strap and no padding. I give 5 start considering the price and quality. Still I need to see how it holds up over longer time.

Untragbar
Auf den ersten Blick (Hersteller-Foto) ein guter Rucksack. Das war’s aber auch schon. Trotz der vielen Verstau- und Verschlussmöglichkeiten knickt das Rückenteil ein, da es mit nichts verstärkt wurde. Egal, ob leer oder gefüllt; das Rückenteil berührt nicht mal den Rücken. So schlampert das Ganze um Bauch, Rücken und Schultern. Keine Kaufempfehlung.

Me encantó
La acabo de recibir. Ya la inspeccione toda y me encantó. Muy buena calidad, espacio y compartimentos. Yo buscaba una mochila para camping que tuviera zíper que abriera mucho para poder ver la ropa que llevo porque las que se abren por arriba como bolsas no me parecen muy prácticas a mí. Esta es lo que yo buscaba.
