Sizing Tips:

• Sizing is based on your natural waist, not your hips or pant size. 
• Measure against your skin.
• Take your measurements in front of a mirror.
• Make sure your tape measure is level on both sides. 
• UnderCool needs to fit your body like a glove to give you the best cooling support. 
• You will wear a size smaller than you think. 

Men's Sizing Guide:

• We recommend ordering a size smaller than your usual T-shirt size.
• (If you wear a large T-shirt, a medium UnderCool will fit best.)
• Sizing is dependent on your natural waist size, not hip or belt size
• You will wear a smaller size than you think. 

1. Stand or sit up
straight and tall.

2. Bend at both sides.
Where you naturally
bend in your natural

Cooling Pack Care and Storage Recommendations:

• When not in use always store Cooling Packs in the solid state, this means the fridge, freezer, or a room less than 70F/21C
• Cooling packs left in their melted state for extended periods of time will result in rapid aging and reduce the lifespan of the cooling packs.
• When handled properly packs should last 2-3 years, and our recycling program provides deeply discounted replacement packs.
• To wash your cooling packs, use warm soapy water in the sink. Do not put them in the washer, dryer, or dishwasher.

Please review our Return and Exchange Policy, Warranty Policy and User Guide.
