Measure at waistline.
Measure from the small of your back, sloping downward to a point 3"- 4" below your navel. For men, this is your pant size.
Choose a Short Torso (ST) model if you have less than 1" of space between your ribs and hips.
Discontinued styles. They differ from current Back-A-Line belts in three ways: 1) Cotton lining rather than a wick-away lining; 2) Old-style lumbar pad has a different shape (less curve), is a bit stiffer (takes time to break in), and is longer on the sides; 3) Larger sizes run small. You may need to size up.
