How to find your size:To measure waist circumference:
These vests are adjustable at the waist with elastic straps and hook & loop tabs. Therefore, they will fit a large range of sizes.
Wrap a measuring tape around your natural waistline (usually across your belly button), making sure to keep the tape parallel to the group. See where the measurements fall on the size chart. Don't forget to add an inch or two to accommodate the cooling packs.
Please note: the weight range is simply a guide; there are many exceptions for different body types.
