SHARKMOUTH Hydration Backpack, 900D Polyester with 2L Leak-Proof Water Bladder, Keeps Liquid Cool for Up to 4 Hours, Tactical MOLLE Pack for Cycling, Hiking, Running

Works great. Used for airsoft games 4+ hours. Water in the tube does warm a bit but after you pull that through the bladder keeps the water nice and cold.

I just got back from Colorado and this pack kept my liquids cool for over 6 hours while on while on the trails, I put it in the freezer for about An hour and a 1/2 or so before going on our hike. It stayed cold all day we had enough room to put our things keys snacks and such and there was actually another pouch that had a tie down or you could tie stuff to the pack. Personally I loved the Gray pack and it came with a cool little removeable (velcro) American flag patch with a blue stripe .... nice touch!! These are interchangable I believe so 8n the end you can put whatever make you happy on your pack.

Overall good construction and quality for the money, i just thought it be a bit smaller and brighter colors idk

Too big for me to wear at the Y. Great gift for my Brother.

Its Bigger on the inside! Amazing amount of storage. High quality zippers. Taken on a 4 mile trek and in the rain. Very pleased.

Exactly as it was discribed my husbnd loves it!!!

Great Pack For taking walks or hiking with the dogs and comes with an awesome patch to support the Blue

Great size! Perfect amount of storage.

Havent used this yet it just came. But upon inspection I was very pleased. It appears to be made of good quality material as advertised, and the water blater sits in an insulated pocket in the pack to keep it cooler for longer. Cant wait for my son to use this on our next hike!!

Amazing! One of the best purchases Ive made on Amazon. Love the water supply. Very comfortable to wear. Built to last and the quality is superb.
