⁃ I purchased this bladder as a replacement for the previous one I used in the Nathan Vapor Air men’s hydration vest. (Size L/XL) ⁃ It is a direct fit to the Nathan Vapor Air vest pouch at the back. ⁃ Sadly, it doesn’t come with the magnetic hose magnet that connects the hose bite valve to the vest itself on the Vapor Air. I went to the Nathan website, chatted with a representative and the representative sent me, for free, a magnet together with a hose. Thanks Nathan for standing behind your products. ⁃ It comes with calibrations and has a maximum fill line beyond/past which you can’t fill. ⁃ The clamp that closes the hydration bladder together works well and it is airtight/watertight. No leaks whatsoever from the top. ⁃ Wash the bladder with a vinegar plus lukewarm water solution the first time you use it and immediately after use, each time. Hang it to dry as I have seen people complain about mold on older hydration bladders that were not aired out properly. If you use colored fitness fluids eg Gatorade, hydration solutions, clean and rinse it immediately after running/use as the bag will start discoloring/adopting the color of the drink/solution. ⁃ I have used it in 2 full marathons and 3 long training runs and it has performed well. I hope that it shall last long. ⁃ The bite valve works perfectly. After using another bite valve from another hydration bladder that leaked after a few uses, I appreciate how easy it is to use the Nathan bite valve. You don’t have to twist it regularly to get the right amount of fluids coming out. ⁃ It has a quick disconnect tube that ‘feels right’ when you are connecting or disconnecting the tube/hose from the bladder. ⁃ Since I wash and rinse it of its contents after every use, I am able to use different fluids and not taste them after switching them between runs on different days. The taste doesn’t linger like it does on many plastic items. (But you have to wash and rinse it first.)

Fits well in my Nathan running vest. 2l is probably more than I need but it performs as advertised.

I purchased this bladder in 2022 and its going strong. Easy to fill, clean, and dry. The hose is easy to disconnect and re-attach. I'm purchasing two more to replace my CamelBak bladders which have become difficult to open and close as their plastic material aged. I'm very disappointed in the CamelBak bladder design which I had previously invested in the past. CamelBak carriers are nice, but the bladders are too difficult to open, and if not closed just right, they will leak. Other similar styles may be as good as these Nathan's, but the Nathen's work well for me so why change.

I needed a replacement bladder after having my water pack for years. I was able to order this on (thank goodness) and it saved me over $100 from having to order another high quality Nathan water pack. I use this on my runs and when I am running half marathons. It stays put, doesn't leak and for the most part, stays cold! The water pack also does not impact the taste of the water and I'm able to clean and dry it in under 5 minutes. Love this product!

Easy to clean. Easy to use. Fits any back pack really. It’s better to just buy this instead of a whole water bladder set. Though there were some leaking during running, so put it in a bag to catch the water

This was a great replacement bladder for my older Nathan bladder. I filled this up with my electrolyte water and had no issues with leakage. The seal on top really keeps the fluids inside the bladder. I have taken this on long run and it has worked like a charm. I am so happy I found a replacement bladder here on Amazon!

I used this on my first ultra-marathon. The hose disconnect is very reliable without fear of leaking. My crew would replace the emptied bladder with this one refilled by simply disconnecting the hose while I kept wearing my Nathan hydration vest. This saved me time at the water stations. The top closure is very secure, as well. I really like that the bladder can be turned inside out to clean and dry! My only critique is the bladder does move/jostle in my hydration vest, but that’s more a reflection of the vest than the bladder.
