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

I used for the first time today and is leaking from the bladder. Went for a 7 mile hike and just ended up with a wet back and backpack.

Great quality! I use this at music festivals and its perfect!

Only thing is the bladder. I got a different one,so not sure about the bladder. Also nice if it had a way to hold bike helmet on the bag its self.

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.

Good quality. Good zippers. Plenty of room for a day hike.

Works great and has lots of storage for being such a small bag.

Great product

Earlier this year I had my previous Sharkmouth pack stolen. I had traveled with it for three years and used it as both a hydration pack and a day-pack.. I attach it to my backpack with my computer and accessories inside so that I could easily carry them separately on trains, planes, etc. I liked the bag so much I ordered another as a replacement...and promptly through the hydration bladder away and bought a different one. The bladder that comes with it is cheap plastic that is impossible to fill completely submerging it and screwing on the top. Additionally, the tube screws (awkwardly) into the bladder and must be removed from the pack with the bladder when filling or it will leak.

Great pack. Use it for running and biking. I highly recommend it.

Used this for my first spartan race and it was definitely a solid choice
