okay, I need to get a backpack. I've decided to go external frame. Now my question is what size do I need?
I'm 6'2" and will be doing overnighters with my 7 yr old. Don't need cold weather stuff as I'm in the Florida panhandle. Will be doing a summer trip in the Smokies, but thats in July.
So I'll pretty much be carrying the load for the two of us.
I know the correct answer is goto the store and pack a bag with everything you think you need. However, that's not possible with me. Maybe able to swing it, but I don't think so as I don't have any stores around my area.
So if I have to order blindly, what cubic load should I get as a minium?
