I got a look at an Osprey backpack and resevoir at the w/e. A great bit of kit, but I dont want to spend that kind of cash on a backpack. Its the resevoir that I think is a really good idea. Its stiff, so you can slide it into your pack easily. Are Osprey the only manufacturer that do this? The bladders are £24 on there own!
The mouthpiece magnet clip to your shoulder strap is pretty neat too, but I'll live without on my Bikehut cheapo backpack.
Camelbak used to (and maybe still do) soemthing called an unbottle which is just a bladder wrapped in insulating and protecting foam and fabric, for you to slot into your bag. It also has straps so you can strap it to the outside.
