Fit & sizing notes for the Khaki Field Murph 42

  • Width: buy 22mm straps. Tapered straps listed as 22/20mm or 22/18mm fit too; only the first number has to match. See strap sizes explained.
  • Spring bars: 22mm long. We haven't confirmed the diameter for this model, so measure the old bar before buying replacements (spring bar sizes).
  • Strap thickness: at 11mm thick it's mid-thickness, so most straps suit it; padded leather and NATOs both balance well.
