In the past I've always used (heavy) internal-frame packs.
I'm finally getting into the ultralite range and want to go with a
frameless pack - but I'm concerned about being able to transfer weight to
my hips (because of a tender back).
I use a neo-air pad and love it - - but I wonder how much it helps
to have a closed-cell pad to help frame the pack.
Any thoughts would be appreciated.
