Hot to Go Vest

The Hot to Go Vest is powered by a plant-based phase change material engineered to maintain a refreshing CoolNow™ 80° cooling temperature when stored in room temperatures up to 75°F. Unlike battery-powered cooling systems or bulky ice packs, the vest activates naturally through contact with body heat, helping draw warmth away from the core for wearable cooling comfort. The cooling technology is designed to provide at least an hour of cooling comfort, depending on body temperature and environmental conditions. As body heat transfers into the vest, the cooling material gradually changes from a frosted appearance to liquid. Once the cooling phase is complete, simply place the vest back into a room temperature environment up to 75°F to naturally reset and cool again.

Yes. Hot to Go Vest is designed for lightweight, wearable cooling comfort while working, walking, gardening, or spending time outdoors in warm conditions. Powered by plant-based CoolNow™ 80° technology, the vest can provide at least an hour of cooling comfort, depending on body temperature and environmental conditions. Once the cooling phase is complete, simply set the vest aside in a room temperature environment up to 75°F for approximately 30–60 minutes to naturally recool and reuse.

Yes. Even when worn over lightweight clothing, Hot to Go Vest can feel refreshingly cool because CoolNow™ 80° technology is designed to help draw heat away from the body across the core. Since the body’s core temperature is naturally much warmer, the vest can provide noticeable cooling comfort during overheating, outdoor work, warm weather, or extended time in heated environments. One of the biggest advantages of CoolNow™ 80° technology is accessibility and convenience. The cooling vest stays cool when stored in room temperatures up to 75°F, making it easy to keep nearby and ready to wear without refrigeration, cords, batteries, or bulky ice packs. Designed with full front and back cooling coverage, the vest delivers wearable cooling comfort people can comfortably use in warm conditions.

Hot to Go Vest is designed to stay cool when stored in room temperatures up to 75°F. If you’re working outdoors for extended periods in hotter conditions and are not near an indoor or shaded room temperature environment, we recommend storing the cooling vest inside a cooler between uses to help maintain its refreshing CoolNow™ 80° cooling comfort and keep it ready on hand when you need a cool down. For best results, place the vest inside a sealed waterproof plastic bag while in the cooler to help keep it clean and dry until ready to wear again. Keeping the vest cool and easily accessible can be especially helpful during hot working conditions or moments when you may begin feeling overheated or experiencing signs of heat stress.

Hot to Go Vest is designed with adjustable straps that allow for a more custom, conformed fit across different body shapes and sizes. The lightweight vest is designed to comfortably wrap around the core with full front and back cooling coverage while allowing flexibility for movement during work, walking, gardening, or everyday activities in warm conditions. The adjustable fit also makes it easier to layer the cooling vest over lightweight clothing when needed. If you’re not satisfied with the fit, the vest may be returned within 30 days in accordance with our return policy.
