SHARKMOUTH FLYHIKER Hiking Hydration Backpack Pack with 2.5L BPA Free Water Bladder, Lightweight and Comfortable for Short Day Hikes, Day Trips and Trails

The Good: The build quality and stitching of the backpack is wonderful, and I have only just recently developed ripping in the fabric by my own fault (over stuffing with a thick jacket). It is plenty adjustable and large enough capacity for shorter hikes/bikes during the day for both water and food. The price is also wonderful. The Bad: The bladder is a push-plug type bite valve. This (in my case) leaked quite consistently, which always resulted in a soaked left leg when biking. The leak was not large nor fast, slow and consistent and rather annoying. However, this never affected running out of water or needing a refill even on my longest hikes/bikes. My recommendation to fix this issue would be to upgrade to the lever type bite valve that you can find on Camelback brand. My Experience: I have used this backpack 2-3 times a week while mountain biking for 7 months and it holds a perfect amount of water, such that I never used it all even on my longest bike rides. It has enough space to carry all the essentials, plus a little more. I carry a multi-tool, low-profile knee pads, a wallet, keys, a cell phone, a tire pressure gauge, and chain lube, and a small packable jacket. This is the absolute capacity of the backpack with a full bladder (requiring a little bit of force to get the zipper closed.

The bag is fine, but I bought this for a hydropack. The water doesnt lead, it just wont come out through the straw. Went without water for my hike. Had to cut it short. Worthless

Love this backpack and perfect size for a petite person. But, I can only give 4 stars because it does not have the outside mesh pockets. Otherwise, its nice quality backpack.

Bag itself is decent quality. I like the small details they’ve put into it. Mine had one issue that was resolved through amazon. The bladder had a small puncture on the back of it. Make sure you check the bladder before planning on using it. The replacement one I received had a similar indentation where the defective one was. Could be a quality control issue. But it’s a decent bag despite the issue.

The bladder developed a leak after a few months. They sent another one for free and it lasted about 6 months. Very disappointed. Will never buy again!

Tube was difficult to drink from

Excelente stuff

Rather than paying $ $60.00 or more for a brand name back pack I looked to Amazon for help. The Sharkmouth Hydration pack works great. Well constructed and with easy to use zippers. The pack meets all of my needs while I am hiking or biking. I would purchase this item again !

Good looking bag, seems like it will last havent taken it out enough to give a full honest opinion
