Whatever outdoor activity you are planning, you always reap dividends by wearing the correct piece of clothing. Summer months are usually dominated with a need to control perspiration and to try and keep as cool as possible. A good way to achieve this is to wear baselayer cooling underwear and lightweight outdoor socks. In cooler Spring and Autumn temperatures you may need to wear baselayer thermal underwear and partner these with windproof jackets such as soft shells or fleeces. If the winter months are particularly cold then extra thermal layers will need to be added to your baselayer thermals, this may be heavyweight thermal underwer or a down jacket or gilet.
