All of our vests are cut large, to fit over a heavy shirt. Please measure carefully, and use the following table as a guide, for both men and women, as well as for juveniles and smaller adults.

MANY of our customers find they need a size smaller than usual. We urge you NOT to rely on your usual size, but to measure yourself, just below the armpits. (If you don't have a tape measure, just use a piece of string or an extension cord or a bathrobe sash. Then measure that with a ruler or yardstick.)

For better fit, we have expanded the information on our sizing. For many customers, the first two columns (Nominal size and their chest measurement) are enough. But some people have more precise needs. We have added the actual interior chest and waist measures (circumference) for each size, and also the length (collar to tail hem, in back) for each size in each style of vest we sell.

Accuracy: like most garments, the exact measurements may vary from one sample to another. These measurements are within about 1" for our entire stock.

We recently added Juvenile/Smaller Adult sizes in our Sports and our new Mountaineer models, and also in our new Commando-style Travel Sweater. Same styles, but arm and neck openings are cut slightly smaller to fit a smaller person's frame. (Available color sets are different from those of the regular adult sizes.)

Comfortable fit: For any adult vest, we recommend 6-11" of overlap or slack between your chest measurement and the actual interior circumference of the vest. This leaves you with room for movement, for comfort, and for shirt and/or sweater. For juvenile sizes, we recommend 4-8" overlap. [* Exception: for the UltraLite model, see special note below the Chart.]
