How to dress for outdoor sports
When doing outdoor sports, the best choice for you to dress is to establish a clothing "system" composed of multiple layers of clothes to adapt to the influence of outdoor weather changes on the human body.
Layering means wearing several layers of light clothes, not just one or two thick ones. The layered dressing "system" is more flexible. You can put on or take off a certain layer of clothes according to the weather and activities. And more efficient. Multi-layer clothes can keep more air around your body, making you feel warmer than a layer of clothes and occupying less space in your backpack.
