My 10 year old Camelbak pack just died on me today and while looking around at hydration packs for something of comparable size I became confused on the cubic inch sizes.
So here is my question: For an average day hike pack, what would be an adequate cubic inch size?
How about a pack for 1--2 days/overnights?
And the cubic inch space of a pack for a 3--4 days and/or a pack for week long hikes?
Now I know the monster packs will be high, like 5000-7000 cubic inches, yet according to some info I dug up on my discontinued pack, it may look like a regular size book back pack, but it is supposed to be around a 2200 cubic inch capacity. Here is where I am stumped: The new pack I was gonna get from Camelbak is larger in size, but smaller in cubic inch space(only 1900) and the business rep told me that it was an over nighter pack. How can that be? I mean my busted day pack had a bigger cubic inch space and there is no way it could be used for more than a day hike.
So help me out here. What's an average size for a day pack, overnight pack and weekend pack?
