Belt Size Chart

Measurement Note: Measure around your waist with a plyable tape measure. Do not "suck in", measure in a relaxed state and pull the measuring tape snug against your body. Use this measurement to choose your correct belts size. Review the size chart carefully as you may be within the range of two sizes. Pick the size where your waist measurement will be in the middle of the range. For example, if your waist is 35 inches, you should choose the size Medium as it is in the middle of the range for the size Medium (this way you will have extra belt holes if you lose or gain weight). The sizing may vary depending on your body and whether you are planning to loose or gain weight.
