The key to effective dressing in cold weather is layering. Your body has its own heating and cooling system; layering can maximize the efficiency of your body system and allow adjustment to various levels of exertion so you can maintain a comfortable temperature. Polypropylene thermal shirts should be the first undergarment next to your skin. This is the most critical layer to ensure warmth. When participating in outdoor activities you will inevitably begin to sweat; sweating is your body’s way of cooling itself. Your next-to-skin layer or underwear should be made of a material that will pull the sweat from your body keeping your skin dry and comfortable. The process of pulling sweat from your skin is often referred to as “wicking.” Thermal shirts designed to wick come in an array of materials, some natural and some synthetic. Polypropylene is a superior fabric to others such as cotton. Cotton and many other fabrics wick sweat, but retain it and take too long to dry, keeping your skin wet and cold. Polypropylene base layer shirts do not absorb moisture so it dries very quickly. 100% polypropylene is not only the best in terms of performance it is also the best value.

Military Thermals long underwear complies with the US Military’s Battle Dress Uniform (B.D.U.) standard of sizing. As such, there are some size characteristics to be aware of. The sleeve length tends to run short, by design. The purpose of leaving the sleeve length shorter is to ensure that layered clothing does not start to stack up at the cuff. The thermals, being the base layer, have the sleeves terminate higher on the wrist to leave room for the outer layers. If you would like your sleeves a little longer, consider purchasing one size larger.
