3 layer principle

Ground Principle:

During physical activity we produce surplus heat. In order for the body to maintain its normal temperature we perspire. When the perspiration evaporates it uses the surplus heat and we can maintain a suitable temperature.
When clothing is necessary, it is important that the features are technically compatible, i.e. that evaporation can take place unhindered.

The layer closest to the skin must be perspiration transporting. If it is not perspiration transporting, the perspiration will condense here and weaken the skin and create an uncomfortable damp feeling. The second layer acts as a “buffer layer”. Here the perspiration can be stored until it has evaporated.

The third layer acts as protection against wind and water. However, the perspiration must still be allowed to pass out from he inner layers.

In essence, the problem is that our activity level often varies a great deal. We either get to cold or overheat. The 3-layer principle can to a large extent even out this condition, so you feel snug and comfortable.
Thoughtfulness and experience are also necessary. It is not wise to wait till you have overheated.

Layer-1:

Geoff Anderson™ has two different types of perspiration transporting underwear in the program:

1: Sirius™ which is non-insulating and dries extremely quickly.

2: Klin™ which is slightly insulating and semi- to quick-drying.

Choose which type underwear according to the activity level.
By using these types of underwear, the perspiration is transported from the skin, through the underwear, to its outside surface. Here it quickly spreads out over an area far greater than the contact point (between skin and fabric) and evaporates.

Layer-2:

Apart from the different fleece jackets, Geoff Anderson™ has two different types of specialised interlayer in the program.

1: Evaporator™
Which is insulating and quick-drying.

2: Thermal 200™
Which is extremely insulating and semi- to quick-drying.
Both these products have the ability to absorb and transport the surplus perspiration/steam.

Layer-3:

Waterproof jackets and trousers.

Offer protection against the elements e.g. rain, snow and wind.

It is important to understand that breathable clothing is only able to “breathe” steam – not actual perspiration in liquid form, for which reason, knowledge and correct use of the built-in ventilation options are of great importance when the activity level is at its highest.
