I will be doing a 1 week trek to Kilimanjaro and plan to use the Fstop Loka as the backpack. I will restrict camera gear to one SLR + 1 lens (maybe 2 if I can manage) and a P&S.
For the trek, I will need a 100 oz water bladder. I have reviewed some Camelback products and like the reviews that there are no leaks and hold up well to even falls.
I need your inputs on:
- are there good bladders that can be attached to the backpack on the outside rather than being kept inside the backpack?
- any specific models to recommend (inside or outside models)
