Which should I get? New Pyramid (which comes with a zip) or Sloane (no zip)? Which do you think looks better, and which is more user friendly? Do you think BV will eventually phase out the Sloane with the New Pyramid? I have tried the Sloane IRL and love it (it is just right for carrying on my shoulder - feels safe and secure even without zip). Does the New Pyramid fit snugly in the same way as the Sloane? TIA.
