Dryzone dryers are manufactured using Dampire technology, and contain thousands of powerful, hygroscopic crystals. When placed in damp or wet sports kit, moisture is absorbed and "loked" into the dampire crystals, preventing mould, rot and unpleasant odours.
Dryzones are effective without heat and can be easily regenerated. it is sufficient to put them in the microwave at a medium power for four minutes or to place them on a radiator for 30 minutes.
