HydraPak Velocity Hydration Reservoir (1.5L or 2L), Slim Profile Water Bladder, Self-Sealing Bite Valve, Leak Proof, Reversible, Dishwasher Safe

I use this about 5 days per week and it is a fantastic hydration bladder. Very durable with an easy to use one handed on/off valve to prevent leakage during transport. Wish they came with an extra bit valve, but otherwise it is perfect!

Had another by a very well known brand. It constantly leaked, and was hard to clean. This is really much better! No leaks and it has a universal fit. Liked it so much, got one for the wife as well.

Not cheap, but do love the improvements in this over the stock (leaky) bladder that came with my Nathan hydration vest. The loop near the top makes filling up the bladder one-handed much easier, and the fold over seal is easy to manage and yet secure. I much prefer the top-opening bladders vs. the ones with the big hole / twist-in lid.

I love this hydration reservoir but I had to buy a second one cause my first one got munched on by a rodent while camping and the new one came with a small hole already. Had to return it.

I had purchased a hydration vest that didn't include a bladder....so I did some research and found this one.Easy to assemble/dis-assemble. Easy to clean.....the bladder inverts so you can dry of the inside.I have filled it to the brim, and still had plenty of liquid after a 15 1/2 mile run in the heat and humidity.I highly recommend this bladder.

Replaced my leaking 2.0 liter USWE bladder. It works just as well and was plenty enough water for a bike park. Seems like a better quality of materials than the factory OEM bladder.

Bought this to replace the camelbak bladder of my child’s mini mule that is forever leaking and soaking her clothing resulting in melt downs. Fits perfect, easy to fill and seal shut. No leaks. The tubing is a bit longer but I’m thinking this actually is a plus allowing the tube to cross over the body and have room to pull it up to drink. I’m not sure what the rubber loop on the pouch is actually for but seems you could use it thread the tube through and adjust length inside the pack.

This might work for hiking, if you only intend on filling up 2/3, and never plan of filling it up prior to immediately putting it in your pack and staying your adventure. Maybe.I found the slide-to-seal a little suspicious from the start, but figured I'd give this one a try.Usually when I'm using a bladder, I'll fill it up the night before, and leave it in the refrigerator overnight, so it's ready to to in the morning. This one leaked. I figured it was because the seal wasn't designed to be on its side. But it continued to leak when I started running until I drank about 0.5 L.I'm not talking about a massive leak, but it's enough to be annoying and make me pack damp. And enough to make sure I don't put anything that can't get wet in a different section of the vest.This hard plastic on the slider also rubbed my back through my vest. If I wore a T shirt it was just annoying. But if I wore a tank top / singlet it wore my back raw.I typically only use hydration vests for ~10+ mile runs, road and trail. Before this I had a super cheap one that came with as cleaning kit and it worked way better. Very disappointing.
