It's no fun being cold when out in the elements but many people will be surprised to learn that it could be potentially dangerous, due to the effects of hypothermia. Hypothermia is a condition in which the body's core temperature of 37°C drops below 35°. Wind chill accelerates the onset of hypothermia. When taking part in active sports at just 30 km/h, (that's less than 20mph), the wind-chill effect can reduce the external temperature by over 10°C, so it's easy to understand how vulnerable people can be to this condition.

Wearing Cold Killers windproof thermal clothing as a mid layer will dramatically reduce the chilling effects of wind and rain.

Hydrophilic membranes have a solid structure that physically stops water passing through the membrane. They breathe by absorbing and dissipating sweat through the diffusion of water vapour molecules. The chemical structure of the membrane is made up of hydropholic (water loving) groups that attract water vapoumolecules. Driven by the greater heat and density, the water vapour molecules move from one hydrophilic group to the next (somewhat like stepping stones).
