Nathan Hydration Bladder BPA Free, Water Bladder for Hiking Backpack, Hydration Backpack, Hydration Pack, Running, Walking, Obstacle Course Race, Cycling

⁃ 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.)

I’ve used a Nathan pack for years with my MTB. I needed the replacement bag and it works great. Fit right in, clean, ready to use! The Water flow is consistent , it is durable and comfortable.

This fits even better than the original one, which is slimmer and longer. Moreover, I can use it on several of my running vests.

I needed to replace an older version of my Nathan bladder. This was an exact match, fits in everything I used in my pack. No leaks! The storage capacity is a full 2 liters and fits in everything I used it on. It's a little bit of a pain to clean the connections, but is still good.

My first Nathan bladder lasted five whole years, which is honestly iconic for how much I used it. It finally broke, so I grabbed this new one — and it’s already doing amazing. The material feels sturdy, the seal is tight, and it fits perfectly in the bag I use to carry it. No leaks, no weird plastic taste, no drama. It’s super easy to fill, easy to clean, and perfect for hiking, walking, running, or just being in your “I need water on me at all times” era. Nathan really doesn’t miss with their hydration gear — reliable, comfy, and built for people who actually use their stuff. A solid 5/5 — hydration queen behavior.

Good replacement! Fits perfect in my Nathan pack and holds a good amount of water.

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 bladder has been great. I’ve been using it for a while now. I’ll throw it in my Solomon vest for trail running or my 17oz backpack for hikes. Fits perfect in both. Has the usual bladder taste, but nothing a mixture of water, baking soda, and lemon juice won’t fix.

Perfect for me, great easy to clean.

Exactly what it was said it was. Thanks

Nach 3 Nutzungen fängt es an zu tröpfeln, richtig mies!!

An sich eine schöne Trinkblase. Leider war sie nach wenigen Läufen kaputt. Es kleines, kaum auffindbares, Loch an der Seite, wo kontinuierlich Wasser austropfte, sodass der ganze Rucksack durchnässt war. Beim Ersatzprodukt das gleiche Problem.

Ordered it, used it once with water and it turned into this yellow looking color. Contacted Nathan support they assured me this is wrong. So I sent it back to be replaced as I thought it's a product ion problem got this instead which as you can see has the same issues.
