Mazama Designs Windigo, Top Fill Hydration Bladder, Replacement Water Bladder with Insulated Hose Fits Most Hydration Pack Water Backpack Applications, 2L / 70oz

I needed to replace my old bladder because every time I used it I found it difficult to securely close. With this Mazama Designs bladder, filling and closing is easy! I also like the way I can dry it thoroughly. I primarily use it for mountain bike riding and hiking and so far I find it to be an excellent choice!

As far as it goes this thing is pretty awesome. The way it closes is nice, the insulated tube is great and the bite valve is cleaner than the one it's replacing. The down side, for me at least, is that this doesn't really fit inside my Nathan race vest very well. I had to wrestle the big plastic handle off to get it into the backpack, otherwise it was too tall. Also the closing mechanism at the top of the bladder is not small so that had to go lopsided. It fits but barely. I imagine if you got a pack that this thing fit into you'd be really happy.

this is an amazing water pack. the hose disconnects easily for cleaning. at times it disconnects on its own but you can re-clip it. it holds the water well and easily fits into a water backpack with cooler. I had a backpack from costco that it fit into.

This is a very nice Hydration Bag. It fit nicely into my High Sierra backpack and so far no leaks. I like that it has that sturdy yet flexible stemp which helps to keep the bag upright without putting any additional strain on the shoulders. I received the bag quickly and it was also packaged very well.

This is by far the most intelligent design I've seen yet in a hydration system. Super easy to fill and clean. The handle makes it very easy to slip it in and out of backpack and the bite valve works great. Definitely hands down the one I will take on my hikes/climbs.

This is the best bladder out there now. The magnetic clip for the bite valve, the removable spine to help insert it into a full pack, the locking bite valve, the quick release for the tube, the insulated tube, there's just no reason to pick a Camelbak over this. Totally recommended.

Hands down the best water bladder on amazon. Can't believe it didnt show up at the top of my searches. Absolutely no after taste, great release mechanism and more.
