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.

Love the pack . goes on every day hike with me and well built

Been using this for my jogs on the river trail and works perfect. I went on a 10 mile hike last weekend & im still loving the purchase. It sits on my upper back instead of the backpacks you can get at REI (great for light backpacks) which are bigger and sit on the lower back or hips. Its a small 2 liter, yet how much you can put in it for a 10 mile hike, well worth the purchase. I also like the support the blue flag. Thank you for creating this. Great purchase.

Love this. Works perfectly small pack.

This is a perfect small pack for hydration and/or a long bike ride/hike. Seems very sturdy, good zippers, just the right size between a regular backpack and a small hydration only pack. I can use the hydration pouch and also a bring another shirt, small pump, keys, wallet, phone, multi-tool, etc. The hydration compartment is insulated and keeps the water cold (you can also just put 2 plastic water bottles in there instead). The only complaint is the waist straps are way too long (I’m on the skinny side) and flap around. I used small Velcro straps to roll them up though so they wouldn’t catch in my rear wheel when I ride.

Water warms up pretty quickly. Even if I use ice cold water it warms up after about an hour. The only time it lasts long is if I fill it all the way with ice then water then more ice and keep going until its completely full. That only makes it last maybe another hour or so.

Much larger than it appears which may be good or bad depending on purpose. Could see it being a nice day hike pack but was too large and heavy material for distance running, mud runs, etc. which was my intended use so I ended up returning.

Great water pack the perfect size for mountain biking for a long ride

So far my son really likes it. It’s a small backpack size, so bigger than a regular camelback. My son said he will use as a hydration pack and to carry items with him. I like the wide opening for water, this will also make it easier to clean and air dry.

Strong recommend, if u don’t have much stuff, this bag is ur choice
