The Layering System
If you are new to the outdoors, you will hear much talk about 'the layering system' and how you should approach it.
Many people advise a few heavy layers and others lots of fine thin layers. Whichever one you choose, the principle is the same, however we have drafted out a few pointers here to help you select which one is right for you.
The advantage of layering, is the 'trapping of a thin layer of air' between each layer and this will keep you warm. However, if you get hot suddenly and the sun comes out, you can adjust the layer and remove one or more to balance your temperature.
Just keep in mind, that heavy layers are just that. Even if you don't wear them you will still have to carry the garments as you discard them.
Hopefully by reading below you will get a better picture of what you actually need for your own use, rather than carrying too much to start with.
Part 1 - Base layer, mid layer, insulation layer
Part 2 - Windproof smock and jackets, waterproofs, the all-in-one approach, headwear
