The latest post in our from the blogs series features a very interesting article by Chris Townsend on a subject very close to the heart of outdoor garment manufacturers.
The Layer System
We added the Layer System to the outdoor gear glossary some time ago:
The Layering System is based on the concept of wearing a numbers of layers of mutually complementary clothing to chieve the best results rather than one or two thicker, heavier layers. It’s not a new idea, many of the outdoor brands lay claim to inventing the layer system. The three layers system consists of a base layer or thermal underwear that is capable of efficient moisture management and very importantly not cold when wet. Next is an insulation layer, usually fleece. The pile of the fleece allows warm air to be trapped and thereby maintaining body heat. Over the top of all this is the Outer Shell garment usually Waterproof.
There are a number of variations on the Layer System. To name a few, the development of the soft shell has ment it is possible to dispense in some circumstances with the waterproof outer shell because the soft shell offers a degree of waterproof. Synthetic filled, ultra light weight garments could be considers a mid layer. Combination garments of pile and and outer shell are sometimes used to replace either of the three layers.
The Layer System used to be one of the favourite topics of conversation in the industry and recently I have noticed a renewed interest in the topic.

Searching through old files recently I came upon this piece on clothing layers that I wrote for The Great Outdoors a decade ago. I’ve amended it slightly for posting here. I’ve left the field tests as they were – as examples they still apply though some of the specific items are no longer available. The pictures are from more recent trips.
