Layering is the key to staying comfortable and warm outdoors.
As every dedicated cyclist knows layering is the key to staying comfortable and warm outdoors. By wearing layers you surround your body with a microclimate that can be tailored towards moisture, wind and temperature control as well as helping with exertion.
Layers are made up of three vital sections. The most important being the base layer (the section in direct contact with your skin). A good base layer will carry moisture away from your skin towards the air and outer layer where it can evaporate.
The centre layer has two jobs; to continue the dispersal of moisture and to insulate. It is imperative that this layer is capable of retaining body heat. Centre layer garments usually have some form of venting integrated into the design, such as font or armpit zippers.
The outer layer provides essential protection from the elements and should continue to allow the dispersal of moisture whilst allowing air to circulate. There are many different types of outer layer all dependent upon which elements you will be cycling in and the time of year.
All layers are best worn close-fitting but should not be constrictive in anyway.
