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. The poncho is available in one adjustable size that fits most, making it ideal for working environments when the vest is shared with multiple wearers.

2. CONVENIENT AND EASY TO WEAR
This vest is easy to put on overhead. The clean design (with no logos or visible pack pockets!) can be worn over clothing or discreetly underneath. This is a great vest for wearing beneath uniforms or costumes.

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

4. OUR MOST POPULAR COOLING TECHNOLOGIES
This kit includes two complete sets of cooling packs: our best selling Kool Max® frozen water-based cooling packs and our Cool58® phase change packs! Kool Max® packs require access to a freezer and offer the highest level of cooling energy. 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 cooler of ice water on-the-go! See full comparison of the cooling pack technologies in the "How Does it Work?" section. The vest includes four (4) Kool Max® and four (4) Cool58® pack strips. See the size chart for more information.

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.

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 3-4 hours. (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 2-3 hours. (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: The vest circumference is independently adjustable at the chest and waist with hook and loop strap closures. 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: The vest length can be adjusted at the shoulders. 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. The optional extension strap kit includes extension straps for the waist, chest and shoulders. The extension strap kit adds up to 20" in circumference and 5" in length to any vest size. This allows an extra fit adjustment for large people, extra long torsos or extra large chests or waists on smaller people. Click here to purchase the extension strap kit.
