How to Measure Your Chest & Arm Length



  • Wear just an undergarment or nothing at all.
  • Stand up straight with your arms hanging by your sides and breath normally.
  • Run a soft tape measure under your arm pits over the largest part of your chest and across your shoulder blades.
  • The tape measure should be snug, but not tight.
  • Ask a friend to run a soft tape measure from the centre of the back of your neck, across to the tip of one shoulder, then down the outside of your arm to your wrist bone.
  • The Fit

    The measurements given are your own body measurements and sizing for each individual product takes into account its intended usage. This means a size large Crew Neck base-layer will be smaller than a size large Down Jacket but Montane would still recommend choosing the same size.
