The Campingaz Freez Pack is brilliant for keeping drink and food cool for long periods at a time. Simply place the pack in the refrigerator between 2 and 4 hours prior to using, or until it is completely frozen, and then insert it into your cooler. The Freez Pack is ideal for textile or rigid coolers between 19L and 32L. Should your cooler be more than 32L then it's advisable to use two.
The Freez Pack is dishwasher-proof, reusable and safe as it is composed of non-toxic refrigerant.
