7L is a functional-first performance brand that takes inspiration from the the US Military's Extended Cold Weather Clothing System (ECWCS) started in the 1980’s. The ECWCS system consists of multiple layer options that can be worn in combination to provide adequate protection for individuals in temperatures from +40 to -60! Over the years the ECWCS system has gone through multiple improvements with technology advancement and material evolution. The most advanced and most popular is ECWCS Generation III which is designed to keep the wind out, your skin dry, and your behind warm! The system can be broken into 7 layers, consisting of 12 components. These pieces work in conjunction to provide insulation, and wick moisture from the body.
Taking the ECWCS concept, 7L is a brand that manages to fuse fashion with function and performance with style, designing and crafting, fashionable yet functional luxury garments that can be worn in some of the harshest environments on the planet or just shopping down town. Our technically advanced products harness a combination of innovative design, high performance fabrics and technical fabrication, creating a unique experience for the wearer every time. The modular 7L system allows users of fashion or outdoor pursuits to tailor make the demands of their unique environment.
7 Layers of Military Clothing
The first generation of combat / protective outerwear consisted of a simple parka jacket and trousers. 20 additional elements of other individual clothing, including hand wear, head wear and footwear were used in various combinations to meet the cold weather and environmental requirements of the US military (and others).
Generation I was intended to be used as a tri-layer system consisting of:
A synthetic base layer.
An insulated and water or wind-resistant mid-layer made of synthetic or cotton blends.
The outer layer was often made from Gore-Tex and designed for protection from wind, rain and snow.
In total, this system consisted of 23 individual garments including; gloves, mittens, base layers, trousers, parkas, socks and liners.
Generation II remained largely unchanged from Generation I with the exception of Polartec Fleece, renowned for its outstanding insulative properties, even when wet, and its lightweight construction.
EFFECTIVE USE OF ECWCS III LAYERS
The Base Layer: Crucial to the function of ECWCS is a high quality synthetic base layer designed to quickly wick moisture away from the skin to prevent chafing and allow the other layers to work more effectively. The ECWCS system includes a lightweight and midweight option for varying temperatures, metabolism or planned physical exertion, both Levels I (1) and Level II (2) are base layers.
The Mid-Layer: Mid layers are designed to provide the bulk insulation by trapping a layer of warm air against the body. Although the concept has remained the same for years high tech materials including; aramid, Primaloft and Polartec Fleece are now found in mid-layers. These exotic materials offer light weight, better insulation even when wet and are flame resistant or flame-proof. Levels III (3) and Level IV (4) are considered mid layers, though these can be worn on their own in moderate conditions with little wind or precipitation.
The Outer Layer: The last three levels including Level V (5), Level VI (6) and Level VII (7) are considered outer layers designed to provide insulation and additional protection from wind, rain and snow.
Level V (5) is a combination of soft-shell jacket and trousers. It offers excellent freedom of movement, good protection from snow and sleet with moderate protection from heavy, wet snow or rain.
Level VI (6) offers the best protection from wind, rain and wet snow. It features dual layers of Gore-Tex with taped and welded seams that virtually eliminates any intrusion of moisture with outstanding breathability.
Level VII (7) is considered the holy grail for many backcountry enthusiasts especially those who operate snowcats, snowmobiles or spend extended time in dry, cold to extremely cold environments without high levels of activity. Though generally considered water resistant Level VII is best used when temperatures are well below freezing when exposure to water is not likely.
The modular ECWCS system allows users to custom tailor their Extended Cold Weather Clothing System to meet the demands of their unique environment, expected physical exertion and personal metabolism. With decades of development and improvement of materials once too exotic for clothing, our soldiers and civilians have access to clothing designed to withstand the harshest environments without the burden or bulk of previous cold weather materials.
