The vest contains crystals located within the cross panels / pockets. To activate these crystals, initially soak the vest in water for 10 minutes. The crystals in the pockets will swell into a gel. The pockets should now be firm but not bursting. Remove from water, grab the top and bottom of vest and gently twist in the opposite direction to help remove the excess water. The vest should now hang to dry or can be spun dry in a washing machine. Removing the excess water will ensure the lightest possible vest weight. The vest is now correctly activated. The vest weighs between 2 to 2.2 pounds when correctly activated.
The vest must always be in activated (gel) state before use. Once activated the vest can be used chilled, frozen, or heated.
The length of cooling time is subject to outside temperature and amount of body heat being generated. As a guide if chilled the vest will stay cold for up to 30 minutes. If frozen it will stay cold for up to 2 hours. If used in the microwave it can stay warm for up to 20 minutes.
Chilled/Frozen – Refrigerator. The activated cooling vest can be placed inside a freezer bag or plastic shopping bag and placed into the refrigerator or freezer. When freezing the cooling vest, a useful trick is to place a sheet of wax paper or freezer paper between the cooling vest to stop it sticking together. If the vest is stiff (frozen) when taken out of freezer; apply a light mist of water from water spray. The Arctic Heat resealable bag is not recommend for freezer usage, as it is specially designed for the ice slurry application.
Chilled – Ice Slurry. To chill the vest in an ice slurry, or on ice, spread out the activated vest) inside the resealable Arctic Heat bag (if purchased) or a thin waterproof plastic bag. Then seal the bag and squeeze out the air from inside the bag. Place the sealed bag into the ice slurry or ice until sufficiently chilled. In some circumstances the cooling vest can be dipped directly into the ice slurry for a couple of minutes.
Heated. The vest can be used warm / hot. The vest must be in the activated state and then heated in a Microwave Oven. Check the vest’s temperature every 30 seconds until the desired temperature is reached. Heating times may vary according to wattage and settings of the microwave. It is IMPORTANT to check that the vest is not too hot before wearing to avoid burns.
Maintenance and Care
If the crystal / gel pockets start to dehydrate and become flat, soak for 5-10 minutes so that the gel pockets properly swell again. If pockets return to the original crystal state, simply repeat the initial soak.
Whilst in the activated (gel) state, the vest must be either frozen or stored by hanging in a ventilated area to prevent it from going mouldy. Do not leave an activated cooling vest in the refrigerator for more than 24 hours.
If you wish to store the vest for long periods, allow the vest to completely dehydrate (returning the gel to crystals), then fold and store. To re-activate, simply repeat the initial soak.
To wash, simply hand wash in warm water with mild soap for 2 minutes and hang to dry.
Do not use bleach.
Please note: Gel crystals are non-sensitive to skin and mucous membranes. The gel crystals are not absorbed by the skin and are non-toxic. The back of vest only has 3 panels filled with gel.
Warning: Some medical conditions may require advice from a health professional before application. Take extra care when using with children, the elderly, disabled, ill and sleeping recipients. If the gel is ingested seek medical advice.
