I would stick to traditional nalgene for a few reasons, 1 hippie tested (cody lundini recommends them big time), mindfulmu tested (I've used the same three of them for my lunch going on two years and they are still great) and last but not least when your doing anything survivalish having a wide ass mouth for your water container is a must.
I would carry a little ass knife too, I know the perfect one for you too It's light as fuck and super comfortable on your hip. Having a little cheap knife makes those delicate takes when your cold and your hand shakes much more bearable. By the way what do you keep your alcohol in?
