SHARKMOUTH Hydration Backpack, Keeps Liquid Cool for Up to 4 Hours

I have worn this every day for a daily multi-mile training hike (90+min) in the heat (80-105F) of the AZ desert for the last month. The water bladder is well made, holds the full 50oz, no leaks. The water tube screws into the bottom of the bladder, so make sure that it is tight. The tube is insulated and the bite tip is solid with no leaks. The pack itself is well made, with good stitching. The bladder compartment was well insulated and kept the water cool throughout the time it was used. There is plenty of room for extra stuff, even a spare jacket, if needed. The shoulder straps are well made and fit a little wide for my frame, but the chest strap draws them together nicely. The waist strap will maybe fit a 40 inch waist, I did not use it. The only minor issue was that it seems that the camo pattern was starting to fade after 30+ days in the AZ sun....OVERALL a quality product that functioned better than expected for the price.

The media could not be loaded. Very nice pack! Material is really thick and feels very durable. Zippers strong and big. Does not feel like cheap at all. Style, design and storage space throughout very nice. Read a couple complaints of velcro straps to hold bladder. Had no issues there. Just trimmed the velcro to hold perfectly. Bladders pouch in backpack very well insulated. Mouth piece design very nice and easy to use. Whole setup definitely feels and looks more like you should be spending way more for it. Very pleased! Cant wait to use! Filled bladder just to check for leaks etc. Fits nicely full. Very happy with purchase!

First, it’s the best looking backpack I ever purchased, I got the gray and blue camo pattern, it’s built sturdy and the zippers move smoothly and never catch in fabric. The extra pockets are big enough for your wallet, Keys, cell phone, first aid kit, and other items, it extremely comfortable and fits well, I’m 6’3 215 and it’s not to small and rides perfectly, i rated it five stars because I couldn’t find a single reason not to.

I was really looking forward to this arriving, as I've been hiking a lot lately and wanted a small day pack like this with a bladder. Build quality seemed good, it would have been perfect for me, except the adjustable waist belt was way too small. Seems like that component was made for children or very skinny people only. Anyone with a little body fat, or who's muscular/built might have issues with this. Seriously, they saved a few pennies in making the belt too short instead of making them long enough to accommodate more people, so it got sent back. What a shame too, seemed like it would have been perfect otherwise.Edit. Well, I ended up with another one of these. The first one I returned was $38, for the reason I mentioned above. Another pack I bought, the belt was plenty big, but it cost more and didn't come with the bladder it was supposed to, so I had to return it. Thing was, I realized, it didn't need the waist strap. I had like this one better overall for practical reasons. ...was browsing, and noticed a few colors were on sale. I bought the cheapest one, at $23, and will be keeping it. I'll just cut the waste straps off. Have already used it on several 4-8 mile hikes. It's perfect for me. The build quality could be a bit better, and I wish it had some elastic side pockets for easy access, but for $23, I'm not going to complain. I have noticed, that this same exact bag is sold under several different brand names on Amazon. This is a good day pack choice for the price, especially if you get it on sale like I did.

This survived better then I expected.. took to CXI for a week long fishing trip. The zippers are great! The straps have lots of additional functionality.. you can stuff a fly rod in the mesh .. the water bladder is great. Overly surprised about how good this worked out for me.

Very nice water pack. Water stays cool has pocket room for snacks I love the design and color options available. The waist band dose need to be long as described by others. I think even if I was back in shape for my body size it still wouldn’t fit comfortably. Other than that. Everything else is perfect

I got tired of opening up canteens for water during rucks so I purchased this hydration pack. It's a wonderful pack with a lot of room for snacks, notebooks, and other small materials for outdoor activities. However, if you want this to be efficient for rucking, also invest in some clips or carabiners, because there's no real good place for it to hang on the ruck by itself. The bladder seems sturdy enough and survived a couple of squish moments as I sat on the ruck (I'm about 150lbs), but I also wouldn't want to test it too far.

I’m an a 5’5” 120lb female and it have been extremely difficult to find a backpack that is suitable for day trips on my motorcycle. Either the backpacks are too long and sit to low on my butt, two wide for my body size or the straps do not tighten enough to my body so the backpack doesn’t flop around in the wind. BUT THIS PACK is perfect. It holds just enough stuff: 1 First Aid Kit, Registration & Insurance, my GoGirl “she-wee”, 2 compact cold rags, 2 glow sticks, 1 pair of shorts and 1 t-shirt and it holds the full batter (or two water bottles)! The buckles for the hip and chest are extremely sturdy and the cushion in the back is so comfortable. I’ve worn it this past weekend for a weekend long trip and couldn’t be happier with it so far! Highly recommend!
