1. ADJUSTABLE, CUSTOM FIT
It is important for cooling vests to fit snug to the body for optimal cooling. This cooling vest has adjustable hook and loop straps at the chest, waist and shoulders for a snug, comfortable and customized fit.

 

2. CONVENIENT AND EASY TO WEAR

Once the cooling vest has been adjusted for size, it is easy to put on every time with the zipper-pull front. The clean design (with no logos or visible pack pockets!) is available in several sizes. Wear the vest over clothing or discreetly underneath.

3. COMFORTABLE 100% COTTON

The cooling vest shell is constructed of durable and machine washable 100% cotton twill.

4. COOL58® COOLING PACKS

Cool58® cooling packs freeze solid at a moderate and comfortable temperature of 58° Fahrenheit, so they can be activated in a freezer, refrigerator, or even a bucket of ice water. (Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.) The vest includes four (4) Cool58® cooling pack strips. See "6. VARIABLE WEIGHT" below for more information on pack dimensions and weight.

5. INSULATED PACK POCKETS

Packs fit into insulated pockets inside the cooling vest. The pockets have a comfortable all-cotton fabric to protect the skin and an insulated outer composite fabric to direct the cooling energy toward the body. Temperature may also be adjusted for comfort by increasing or decreasing the number of clothing layers beneath the vest or the number of packs used.

See the size chart for more information.

How do Kool Max® water-based cooling packs work? 

• Kool Max® frozen water-based cooling packs require access to a freezer and offer the highest level of cooling energy. It takes more energy to charge these packs in a freezer and in return, the packs offer greater cooling energy than Cool58® cooling packs. 
• These reusable packs deliver comfortable cooling for up to 4 hours depending on environment, activity, and personal metabolism... (Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.)
• Packs are non-toxic and non-flammable.
• Works in any climate - extreme heat and humidity are no problem! The cooling performance is not impacted by humidity or outside temperature.

How do Cool58® phase change cooling packs work? 

• Cool58® cooling packs freeze solid at a moderate and comfortable temperature of 58° Fahrenheit (14.4° Celsius), so they can be frozen in a freezer, refrigerator, or even a bucket of ice water. 
  
• Once activated, these reusable packs deliver comfortable cooling for up to 3 hours depending on environment, activity, and personal metabolism. (Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.)
• Packs are non-toxic and non-flammable.
• Packs do not require a freezer! Packs can simply be submerged in ice water or placed in a refrigerator or freezer to activate. Easy to use - packs can be activated by simply submerging the packs into ice water for up to 20 minutes when access to freezers is not available.
  
• Works in any climate - extreme heat and humidity are no problem! The cooling performance is not impacted by humidity or outside temperature.

• To measure the chest and waist circumference: First, wrap a soft measuring tape around the fullest part of your chest and under your armpits, making sure to keep the tape parallel to the ground. This determines your chest measurement. Then wrap a measuring tape around your natural waistline (usually across your belly button), making sure to keep the tape parallel to the ground. See where the larger of the two measurements fall on the size chart. Please note: If you think you are in between two sizes, order the next size up to accommodate the cooling packs. 
• To measure the vest length: Hold the tape measure at the highest point of your shoulder. Look straight ahead and pull it down to your natural waist. Mark this measurement on the tape measure with your thumb. Please note: When in doubt, order the next size up to accommodate the cooling packs and to prevent the vest from looking too short. 
• Please note: the weight range is simply a guide; there are many exceptions for different body types.
