What’s 3-layer Principle?

Base Layer, Middle Layer, Outer Layer

3-layer principle is a smart dressing method for a large number of outdoor sports and recreational activities. It can effectively keep you either warm or cool, dry, and comfortable in the varying weather conditions.

3-layer principle does not mean you should wear only three clothes. The point is that you should form 3 “layers” according to different functions of each layer so that you can easily handle the harsh weather. To put it simply, base layer for Transportation, middle layer for Insulation and outer layer for Protection.

1. Base Layer - Transportation

Moisture-wicking, Quick-dry, Skin-friendly

Base layer is often worn next to skin because its responsible for wicking away moisture and transporting sweat vapor to the next layer so that your skin could stay dry, cool and comfortable. In cold environment, base layer can be leggings, thermal tops, functional long-sleeve, woolen clothes etc. In warm environment, it can be a functional, quick-dry and anti-bacterial T-shirt, or merely a vest.

 2. Middle Layer - Insulation

Warm, Breathable, Comfortable

The middle layer should not only traps heat firmly to maintain body temperature, but also be able to evaporate perspiration easily.
