As human beings our bodies are fantastic at working to keep a steady core temperature of 37°C degrees but we’ve all got limits. When it’s cold outside, we want to get out and enjoy our favourite sports, but there’s only one thing that’s going to help us to stay warm, and that’s insulation. Call them what you want, puffer jackets, down jackets, duvet jacket or insulated jackets – insulation is the key to staying warm.
Warmth trapping insulation is an important part of the clothing layering system and is often worn as a mid-layer, or in dry cold climates as the outer layer.
The principle behind insulation is very simple. We want to trap the warmth that our bodies create, and keep it as a buffer from the cold outside world. This allows us to maintain our body temperature, keeping us safe and comfortable so we can get on with enjoying the outdoors.
This down jacket guide will help you to choose the right jacket for your activity, and the weather conditions you’ll encounter.
