How to Measure for Fitment

A. Chest

Should be measured just under the arms. If your stomach is bigger than your chest, use the larger measurement.

B. Waist

Measure from center back of neck at spine to the wrist bone.

The heated jacket when worn should be touching the body profile as much as possible, leaving no room for extra movement. Choosing the correct size of jacket depends on the exact chest size. For example, 42 size jacket is a good fit size for a person with 42 inch around the chest. Wear a t-shirt below while sizing your jacket. Wear a thicker garment over the heated jacket for best results.
