It is a well know fact in the outdoor trade that wearing a variety of thinner layers will keep the core body temperature higher than wearing one thick layer as air is trapped between these layers and forms a microclimate. This method of layering also makes it easier to adapt your body’s warmth to suit changes in the temperature / climate by adding or removing layers as required.

The layering system is made up of the following:

Base Layers – A baselayer is designed to be worn next to the skin, so that moisture can be transported from the skin through the fabric and evaporate – this method is called wicking. Wicking is important as it prevents moisture building on the skin and cooling the body’s temperature. There are a variety of different baselayers in the market place to suit all activities and climates ranging from different styles and fabric weights for use in the summer or winter. The key features of a good baselayer should be lightweight, close fitting to ensure maximum moisture transfer and quick drying.

Insulating Layer – An insulating layer should work with the baselayer to continue the wicking process but will also provide additional warm from the cold. The most commonly used insulating layer is fleece with is available in different weights, however there are a variety of options available including soft shell and lightweight down or synthetic filled products depending on the conditions and activity they are required for.

Outer Layer – The outer layer provides protection from the elements and should be selected depending on the conditions you are in. Dry but windy conditions would require a non waterproof shell like a windproof fleece or soft shell, however wet conditions or snow will require something with a waterproof coating or laminate. Selecting a fabric with breathable properties means that the outer layer works with the base and mid layers to increase the wicking effect.

In extremely cold conditions an additional layer of warm may be required either to be worn instead of a waterproof outer in extremely cold but dry conditions or as a throw on layer to be worn on top of your outer when warmth is required for shorter periods of time such as reaching a summit or lunch stops on a hike, however this will effect the breathability of the overall layering system. In these cases a down or synthetic filled product is ideal as it provides great warmth to weight ratio.
