Lightweight Environmental Protection

Overview

The Lightweight Environmental Protection (LEP) is an insulation subsystem developed under the Special Operations Forces Personal Equipment Advanced Requirements (SPEAR). LEP consists of 7 garments designed to provide protection to -40°F (-40°C). The system is designed to be individually configured based upon mission, terrain and climate requirements as well as personal preference.

Components

Layer 1
Silk/Lightweight Undershirt and Drawers
Layer 2
Midweight Undershirt and Drawers
Layer 3
Midweight Stretch Bib Overall
Layer 4
Pile Jacket is fabricated in a heavyweight fleece fabric. It has a collar, zipper front closure, pit zips, two zippered hand warmer pockets, inner pockets and a windproof front and back yoke.
Layer 5
Wind Resistant Jacket is fabricated in heavyweight fleece wind resistant fabric. It is the same basic design as the heavyweight fleece jacket with the addition of wristovers and a hood.

The underwear layers are designed to wick away moisture and provide warmth. The bib and fleece jacket are intended to aid the base layer in moisture vapor transmission and providing a significant insulation layer.

All layers may be worn individually or simultaneously (except jackets) and will fit comfortably with each other. The four non-wind resistant layers are intended to be worn under a windproof, water repellent outer shell such as the ECWCS Parka and Trousers. The wind resistant jacket is designed to be worn as an outer layer and combines the effectiveness of the heavyweight fleece jacket and a windproof, waterproof outer shell.
