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

Purchased for my Salomon running vest and fits perfectly. I haven’t experienced any leaking and holds up in heat and cold conditions. I like that the “straw” is extra long so it can be cross body in the front.

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.

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.

I use this with my Salomon Adv skin 12. Fits well. The product is great but spring a leak near the top of the pack. The side/seam started to separate. I contacted the company and it was easy to file a warranty claim. They shipped me out a new one the next day. 4 star instead of 5 because of the leak. But great and easy service to get it replaced

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.

Fantastic Osprey bladder replacement! We use our osprey bags a LOT during the summer. We have this for about 8 months or so and use it 4-5 times a week. Very good quality and fits in the bag just like the original. Never leaks, retains water perfectly.

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.

Purchased in June 2025, Five months later, the valve leaks. Not happy with purchase. Other than the leaking, I suppose, it was great. But shirt is wet by the time I reach the top of the mountain.
