RallyWrap Sizing Guide
The RallyWrap is one size fits most. If you would wear an XL Tee Shirt size, we recommend getting your RallyWrap with 8 Cooling Packs so that the cooling will wrap around your entire torso.
Using a Fabric Measuring Tape:
- Sizing is dependent on natural waist size not bust size.
1. Stand or sit up
straight and tall.
2. Bend at both sides.
Where you naturally
bend in your natural
waist.
3. Measure where you bend. If you don't bend measure below rib cage but above belly button.
Don’t Have a Fabric Measuring Tape?
You can measure your waist the same way with a straight ruler and:
String / Yarn
Dental Floss
Shoelace
Charging cord from your phone
