Nalgene TPE Big Bore Tanker

I bought this new old stock bladder recently in original retail packaging. The best bite valve on the market, doesn't leak, very high quality, leaves sour aftertaste to water. I used purified water only not tap water. My stock original Camelbak bladder it replaced did not leave an aftertaste with same water.

I have used it for about a month and have had multiple loads of water in it. I mountain bike often with this item. I'm hoping taste issue subsides because this bladder is better in every other aspect compared to my old one.

There is something truly wonderful about the TPE material in this reservoir - we have had many hydration products, but nothing comes close to this - somehow it moves and flexes with you in a completely organic way. There is no taste or odor with any beverage, even when warm, and even though it is soft, perfectly quiet and flexible, you can't seem to hurt it!! What IS this stuff?? Whatever it is, it's perfect for this product. Well done!

I am a fan. Works very simply and is quite stable and durable. I had heard all of the bad things about other Nalgene hydration packs, but never these TPE models. They are made out of a sleeve of material which means that seams are only created on the top and bottom, not the sides as well, eliminating at least 50% of the surface area that is most likely to fail.

Some taste remains, you'll have this with hydration packs.
