• Presently there are woollen underwear having moth resistant treatment which dose not have the pungent moth ball small and a great convenience to the busy mothers.
  

• The perspiration is human physiological phenomenon. People sweat even in the winter.
• Sweating allows the body to regulate its temperature. In summer, evaporation of sweat from the skin surface has a cooling effect due to the latent heat of evaporation of water.
• In the opposite side, evaporation of sweat from the skin surface makes people feel cold in the winter.
• Thus to wear functional thermal underwear that breathable and wick perspiration from body to outer layer clothing for eventually evaporation, will keep you warm.
  

• There are three phases of water which are solid, liquid and gas.
• When melting of ice or the boiling of water, the amount of energy absorbed by a chemical substance during a change of state that occurs without changing its temperature.
• In the atmosphere, when water evaporates from skin surface, energy is transported by the water molecule into a lower temperature air parcel that contains more water vapor than its surroundings. Because energy is needed to overcome the molecular forces of attraction between water particles, the process of transition from a parcel of water to a parcel of vapor requires the input of energy causing a drop in temperature in its surroundings.
• Chicks J-fit Wamer, made from Polycolon, which has lowest conductivity, that breathable and wick perspiration from body to outer layer clothing for eventually evaporation, will keep you warm.
