  • By properly correcting shape rather than just sliding strap material along a single plane, QuickSwap components eliminate dead spots, pressure points and friction
  • Independently pivoting shoulder harness panels contour your body shape for custom load balance on varying terrain
  • Combine with the A3 QuickSwap hipbelt for 15 possible fit combinations on any Baltoro and Deva pack (hipbelt sold separately)
  • Pre-curved components with ergonomic tapering increase the comfort and stability of fully loaded packs

Will these backpack straps fit my REI external backpack frame?

Asked by: tideinc
The A3 QuickSwap Shoulder Harness is designed for use with Gregory packs using the QuickSwap system. It is not compatible with an REI pack.

How thick are the straps? Will these fit my Gregory Reality backpack? Thanks.

Asked by: Life Outdoor
The straps on the A3 QuickSwap Shoulder Harness measure approximately .25 inches thick. The A3 system is only compatible with the Baltoro and Deva packs from Gregory. The harness will not work on a Gregory Reality.

Is this shoulder harness an "improved model" over what comes stock on a Gregory Baltoro 75? My one complaint on the Baltoro I recently bought is that I found the the shoulder straps to be both uncomfortable and under-padded for packing heavy loads.

The A3 QuickSwap Shoulder Harness is the same harness that comes stock on the new Gregory Baltoro pack.

Will these work on a Gregory Zulu 40??? Mine is missing a sternum strap and they haven't had any in stock, frustrated and if these will fix it I would be super happy!!

Asked by: Cabanana
This harness is compatible with Baltoro and Deva packs, but not the Zulu.
