And this is the newer one
Accessory - Streamer - Deuter Sport GmbH & Co. KG
I really love the Deuter bladder, it just got old. So last year I bought a Camelbak because that's what the local shop had. Well I hate it. It's like they over-engineered the bladder and under-engineered the mouthpiece. Deuter has an easy to fill/empty bladder, very simple design that works, and a great mouthpiece that doesn't leak all over my leg.
It looks like the new one they changed the mouthpiece a bit and made the hose detachable. I might just go with the old tried and true unless the new one is really better.
