Macna Dry Cooling Vest
Stay cool this summer.
Unlike other cooling vests on the market, you do not need to hold this under the tap and put it on wet, the clever patented design allows the rider to stay cool for up to 3 days before having to top up the jackets resevoir with tap water.
Simply pour 1/2 litre of water into the Macna Dry Cooling Vest, and the vest then uses your natural body heat, evaporation and some special crystals inside the vest to lower the temperature 10 to 15 °C. Which means if you're riding in the heat and your body reaches 40°C, it'll cool it down to 25°C, a much more comfortable temperature.
It does all this without liquid on the outside, so you'll not get wet or damp. Even under thick leathers, this will work.
The water you put in (just plain tap water) will last for 2 to 3 days. The total weight when filled completely remains under 1 kg (2.2 lbs).
