Most comfortable? Carry as little as possible!
I mostly wear 5.11 pants
I employ a loyal Sherpa who follows me everywhere, carrying everything I might need in a pack basket on his back.

They're seen as tools here, less of weapons.
As it turns out, pretty well. It did dig in a little when I sat down while carrying it pliers up. Switching to pliers down was much better.That's how it should be.
