Back woods Backpacking Pack
Lots of storage space in your survival backpacks, lots of zipper pockets plus plenty of room for your needs

Good quality
A little heavy in the market era of ultra light but sturdy, comfortable and excellent for price.

Great Pack
Excellent pack for the money. Most lightweight backpacking setups cost 100s more and offer less features. This pack has a built in rain jacket, great support for attachments, and plenty of compartment space while being reasonably light. You can find lighter packs for sure but they are WAY more expensive. This one is still comparable weight wise with many of the far more expensive brands. I recommend it!

Side plastic doesn’t hold 1L water bottles:it fell out.
Great bag, lots of room to over pack haha. Padding was comfortable, loved that you could adjust the size.

Hiked Isle Royale with this...
Did not have to use the rain cover and I kept it inside of our tent instead of the vestibule so it didn't get very dirty, but it fit everything I needed for the backpacking trip at a great price. It fits down to a 16in torso okay (my wife is petite at 5', 130 lbs) but you'll probably have to get an expensive Gregory backpack if your torso length is under 16 and you need 55+L. For me (5'8", 260lbs) the pack was perfect. It carried the weight of my stuff nicely except the brain of the bag... It can be awkward when stuff is put in there like a puffy jacket or something. I wish it was just a flap instead of a brain because it feels like wasted Ls. The front pouch doesn't stretch, so you can only put certain things in there if your pack is full. The side pockets are great and the hipbelt is awesome. Fit my 46in hips nicely. I would buy again and would buy this for my wife if her torso was 1 inch longer.

Great value for the price
I took this backpack on a trip to Wheeler Geologic Feature, a 15mi round-trip out-and-back in the Colorado Rockies. Overall it performed very well and I'm glad to have it. Likes: This is a very low cost pack compared to other similar products. It has tall side/"kidney" pockets (12"H x 4"D x 2.5"W) that can easily hold tall water bottles or even small tripods, and it has deep mesh water bottle pockets on both sides that stop big water bottles from falling out. It also has a very large "roof" pouch, two drawstrings to close the top section, a great waist buckle/tightener design, and is made of mostly water-resistant material. Dislikes: Zipper tabs are very small and several don't have string pulls attached. In particular the zippers on the belt pouches are hard to close one-handed, because they don't close smoothly. There is no central hangar strap for a hydration pouch (you have to jerry-rig a string between small loops on the left and right), and the hydration tube port is way too high and only on the right side. Finally, the compression straps on "roof" don't have buckles which means a lot of fussing to store something there, which is also weird because all the others have good buckles. Also, the height adjustment could have a bigger range. I'd say this pack is just about comfortable up to 6'0" in wearer height. Any taller and there just isn't enough adjustment available. I would love to see this company come out with an updated version. The issues to be fixed are really very small and some slight adjustments could make this pack really compete with those more than three times the price. All it really needs are: 1. Better zippers on the belt pouches, 2. Hydration ports lowered, and made on both sides, 3. Two or three more "height adjustment" loops - there's plenty of space for them, they just aren't sewn in, 4. Buckles on top compression straps, 5. Central hangar for hanging a hydration bladder inside.

Comfortable, sturdy, and looks great
I took this on a 7 day mountain backpack trip with a group of teen kids. Each day we tracked 4 to 5 miles up and down the mountain. It had Plenty of ways to adjust it but I found myself not having to make adjustments as much as the more expensive ones that others had. It worked great

Good value but some issues, especially for longer torsos.
This bag is very spacious. The pockets let me organize my gear. I think that it's a good value for the price. However, I had a couple issues with the bag. I think the hip belt is not really well linked with the internal frame. This causes the bag to be a little saggy and puts more weight on the shoulders. I could only really transfer the weight to my hips by tightening the hip belt really tight and loosening the shoulder straps enough that the bag leaned away from my back. The bag is quite adjustable for torso length, but I think I topped it out with my 20" torso. At that length, the load lifters were below my shoulders so I couldn't use them to pull the pack closer to my back.
