HOLY TRINITY: THE THREE LAYERS
An optimal protection against varying weather conditions is created by combining the right items and fabrics. They do however have to complement each other in the right way, so don't just randomly throw them together. There is no use in dressing extra warm if you're going to be soaked in sweat after only two hours of work. The right combination of fabrics will allow you to go on working without being bothered by the weather or your own body heat and transpiration.
The main goal of the outer layer is to protect its wearer against all external conditions. Snow, rain or hail, your top layer has to keep it al out while passing on your own body heat and transpiration moisture to the outside. The ideal fabric for an outer layer is not only breathable, but also wind- and waterproof.
This layer keeps you dry and warm at the same time by passing on your transpiration moisture from the bottom layer to the top layer while keeping out the cold. Fleece, for example, is an ideal fabric for this layer because it is a very strong fabric that passes on moisture while insulating your body against low temperatures.
The bottom layer of your clothing has to ensure that your body heat and transpiration moisture find their way to the outside as quickly as possible. So be sure to wear a moistregulating fabric on your body to keep your skin dry. A wet bottom layer severely cools off the body, a problem that can be easily avoided by wearing for example polyester or a thin type of wool. This makes sure that your own sweat and body heat are disposed of without you getting wet yourself. Wearing the right type of bottom layer prevents you from cooling down too quickly when you do decide to take a break.
A correct application of this 3-layer system is a guarantee for an optimal performance and allows to you work as freely and comfortably as possible.
