Your size chart is misleading. It indicates chest measurements, but talking to a representative, I was pointed to an FAQ where the directions note that it's a shoulder measurement.

This is not listed on the ordering page which only gives the 'chest' measurements (which are actually shoulder measurements). This is misleading and caused me to order the wrong size. A customer should not need to go digging for an FAQ to learn that 'chest' doesn't mean chest, it means shoulder.
