When practicing outdoor sports, you need to protect yourself from the elements (rain, wind, snow, cold temperatures etc.) by means of good perspiration management. The three-layer-system helps you choose the right clothes while taking into account the weather conditions and the sport practiced. Three layers of clothing will keep you dry and warm: a base layer for removing moisture, a mid-layer to keep you warm and an outer layer to protect you from the elements.
Synthetic materials like polyester or polyamide are water resistant: they don’t absorb water. Any moisture moves towards the outside of the clothing so it isn’t in contact with your skin. Wearing a t-shirt made from a synthetic material allows your body to regulate its temperature without feeling cold. These materials also dry very quickly.
