I've got two Camelbaks, an approx 10 year old Blowfish I use for bike riding and running and a 2 year old Commander. Both are great, only gripe with the hunting line is most are 2 litres. I wanted 3, but that means a much bigger pack. It's not quite big enough for backpacking but it's a bit too big for day trips. I'm sure it'll come in handy one day when I can fill it with meat. All the pockets are rather handy, I've got everything nicely sorted and don't have to go rummaging through all my gear to get one thing.
I got it from Snowgum at the Glen (which might not be there anymore? There's one at Knox), they had to order it in though. Cabelas is probably cheaper.
