Don’t buy it!

It leaks from the opening on top. I tried folding the top over again and holding it with a clip but it still leaks. It’s bad enough that cold water runs down my back side. I can’t use it.

Awesome hydration pack!

This pack reduces sloshing because of the shape and keeps my fluids cold even for 20 miles in warm temperatures. I highly recommend! Easy to use and clean.

Great for the PNW

I bought this about 2 months ago to replace a dirty one and I am in love with the insulated tube because running in the winter months in the pacific northwest can cause it to freeze. My favorite part is the no-hands needed nozzle, just apply pressure and the water comes out (do be careful where you place it cause it could leak) but while your running its a game changer.

Amazing Bladder

Amazing bladder. Absolutely love this! I bought it on a wim because it says it does not work with the VAPORKRAR 2.0 4 LITER pack. But there was a review that a woman had bought this for the womans version of the vaporkrar and it fit fine. This was also the case with me so I was very excited since the bladder that fit the Vaporkrar 4 L was not in stock. Great addition and now I'm fully stocked!

Ok but hard to clean

This bladder is ok and seems to keep the water cold through the run. However, the shape of it makes it difficult to clean. With the 2L bladder, I flip it inside out and it gets completed dry very quickly. This prevents mildew from growing. This bladder's shape and thickness prevent me from doing so. The color gray is also not helpful to tell whether there is mildew growing.

Absolute LOVE!!

I bought this to go with my vaporhowe 4L (the original orange vest), i wasn't sure it would fit, but it does. It keeps my water cool and is super easy to clean. I like the quick release feature as it will let me swap bladders during resupply stops, rather then having to refill which will take a little longer and risk me pouring water all over my pack. The vest didnt work out for me, but this bladder is so awesome i ordered a second one for quick resupplying on my long runs.
