User Review: Nalgene TPE Big Bore Tanker
Price Paid: $20
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.
