For most of my life, I’ve been wearing cotton-based clothes. I was taught that thicker multi-layered clothes would keep me warm in winter and thinner lighter garments would be the best way to stay cool during the hot summer season.
While this advice is partly true, in practice, it is very problematic. Consider, for example, when transitioning from the hot outdoors, after accumulating sweat, into an air-conditioned building. The moisture often causes an uncomfortable “chilling effect”. Conversely, staying in a warm building during winter season will force you to take your jacket off, but what could you do about a thick “thermal” underwear?
Well, it turns out that one of the best ways to regulate body temperature is by managing moisture and the best fabrics that do that are synthetics (eg. Polyester, Nylon, etc…), not cotton.
- Bright colors and UPF 50+ (to minimize thermal radiation)
- Loose fitting (to minimize heat conduction)
- Highly breathable and moisture-wicking (to maximize evaporation & cooling)
- Long sleeves and high collar (to maximize shading and protection)
Use the 3-Layer System:
- Moisture-wicking base layer (ensure dry skin)
- Insulation second layer (fleece to stay warm)
- Shell third-layer (block wind and rain)
