The Expandable Cool Vest

From $149.95

The Expandable Cool Vest is made from black Supplex, a soft, lightweight material. The vest is able to accommodate our much larger Heavy Duty Cool packs as well as Standard Cool Packs.

Cool Vest Kits are vests with TWO sets of Cool Packs — $25 less than extra set of packs purchased separately. Select the two pack option for all day cooling with no down time and save!

Heavy Duty Cool Packs have 40% larger surface area compared to Standard for enhanced cooling (less energy expended by your body). We also recommend Heavy Duty Packs for all customers over 250lbs.

This vest is one size fits most — it is able to adjust from average to XL body sizes. XXL is also possible with our 10″ expansion straps for a more dynamic garment range.
