Title: Clothing and Equipment for Cold Weather and Mountain Operations
1 Clothing and Equipmentfor Cold Weather and Mountain Operations 2 Terminal Learning Objective Action Wear cold weather clothing and equipment Condition Given the ECWCS other issued cold weather clothing items and the issued cold weather sleep system with insulating pad under field conditions where temperatures range from 40º to -60º F Standard Soldier used issued cold weather clothing and equipment to prevent cold weather injuries. 3 (No Transcript) 4 Cold Weather Uniform Should
Keep you warm
Keep you dry
Protect you from the wind
5 Extended Cold Weather Clothing System Design Principles
Insulate Any material that reduces the amount of
heat lost to the environment
Layer Several layers of clothing provide more insulation and
flexibility than one heavy garment even if the heavy garment is
as thick as the combined layers
Ventilate Helps to maintain a comfortable body temperature
by allowing excess heat to escape
6 Extended Cold Weather Clothing System Overview
Base Layer also known as inner or wicking layer the base layer(s) are designed to wick excess moisture away from your body.
Insulation Layer intermediate layer(s) that provides volume to enable you to trap warm air between your body and outer garments
Outer Shell Layer external layer that protects you from the elements providing protection from wind and moisture
7 Clothing Guidelines l C- Keep it Clean O- Avoid Overheating L- Wear clothes Loose and Layered D- Keep clothing Dry 8 C- Keep it Clean
Dirt and grease reduce the insulating
properties of clothing
Clean whenever possible
Dry rub clothing in the field
9 O- Avoid Overheating
Causes excess perspiration
Dampness reduces insulating properties of clothing
Perspiration evaporates cooling the body
10 L- Wear clothes Loose and Layered
Tight clothing restricts circulation
Lessens volume of trapped air
11 D- Keep clothing Dry
Moisture enters from both outside and inside
Dampness lessens insulating properties of clothing
Brush snow off clothing before entering heated shelter
Air dry clothing away from direct heat source
Dry leather items slowly
12 Gen II ECWCS Components
Polypropylene undershirt and drawers with standard wool socks (commonly referred to as polypro)
You may be issued a lightweight and/or mid-weight polypropylene undershirt and drawers
Pile Jacket and Medium Weight Stretch Bib Overalls (commonly referred to as Polar Fleece top and bottoms) and/or
Liner Cold Weather Coat and Liner Cold Weather Trousers (commonly referred to as smoking jacket and pants)
Outer Shell Layer-
Extended Cold Weather parka and trousers (commonly referred to as GORTEX top and bottom)
GORTEX gloves with inserts trigger finger mittens with inserts arctic mittens
White vapor barrier boot and/or intermediate cold weather boot (ICW).
Wool balaclava and/or pile cap and/or OR Windstopper Balaclava neck gaiter
13 GEN II ECWCS Base Layer
Polypro undershirt and drawers
Wear next to skin
DO NOT wear cotton undergarments under polypro
Standard issue is shown lightweight and mid-weight are available and may be issued
Worn with single wool sock or two sock system
14 GEN II ECWCS Insulation Layer
Liners Cold Weather Coat and Trousers
Wear over base layer
Same material as poncho liner
Coat has slits under arm for ventilation
Trousers are sized short intentionally
15 GEN II ECWCS Insulation Layer
Polar Fleece Shirt
Polar Fleece Overalls
The USARAK policy is that (IAW USARAK Pamphlet 600-2 policy) (c) The issued black polartec fleece will not be worn as an outer garment while outdoors.
16 Gen II ECWCS Outer Shell Layer
Wear GORE-TEX over base and insulation layers or over base layer for heavier activity levels
Wear the GORE-TEX trousers with suspenders
GORE-TEX water repellency can be restored
Three balaclava configurations
Three neck gaiter configurations
Boots issued in basic training are NOT for cold weather
Below 14º F you should wear the white VB boot
Always wear a contact glove when temperatures are below 32º F
17 Modular Sleep System (MSS)
The complete MSS system weighs about 7 pounds and includes
Patrol Bag is rated 50º F to 30º F
Intermediate Cold Weather Bag
is rated 30º F to -10º F
Vapor Permeable GORE-TEX Bivouac Cover
Intermediate Cold Weather bag goes inside the Patrol Bag which goes inside the Bivouac Cover. This provides protection from -10º F to -40º F for 4 hours of sleep.
The newer ACU style is rated to -45º F
18 Generation III ECWCS Level 1 Base Layer
Lightweight Cold Weather Undershirt and Drawers
Long sleeve top and full-length bottom constructed from silkweight moisture wicking polyester
Material aids in movement of moisture from the skin to the outer layers
19 Generation III ECWCS Level 2 Base Layer
Mid-Weight Cold Weather Shirt and Drawers
Long sleeve top and full-length bottom garments constructed out of polyester grid fleece
Grid fleece provides an increase of surface area for transportation of moisture away from the wearer during movement
Can be worn next to skin or over Level 1 for additional insulation
20 Generation III ECWCS Level 3 Insulation Layer Fleece Jacket is the primary insulation layer for use in moderate to cold climates. Thermal Pro animal fur mimicking insulation provides an increase in warmth to weight ratio along with a reduction in volume when packed. Not authorized for use as an outer garment in USARAK. 21 Generation III ECWCS Level 4 Outer Shell Wind Cold Weather Jacket is made of a lightweight windproof and water repellant material Acts as a minimum outer shell layer improving the performance of moisture wicking layers when combined with Body Armor and/or the ACU 22 Generation III ECWCS Level 5 Outer Shell Soft Shell Cold Weather Jacket and Trousers Made of a highly water resistant wind proof material that increases moisture vapor transfer Increase of breathability improves performance of insulation layers by decreasing saturation due to moisture vapor accumulation Provides a reduction in weight bulk and noise signature during movement Best used when temperature is below 14º F. 23 Generation III ECWCS Level 6 Outer Shell Extreme Cold/Wet Weather Jacket and Trousers A waterproof layer for use in prolonged and/or hard rain and cold wet conditions Best used when temperatures are above 14º F and alternating between freezing and thawing 24 Generation III ECWCS Level 7 Outer Shell Extreme Cold Weather Parka and Trousers Provides superior warmth with low weight and low volume Highly water-resistant and windproof in order to provide wind and moderate moisture protection Sized to fit over body armor For extreme cold weather climates the outer most layer of protection. Meant for static positions 25 ECWCS Care Instructions
Universal care instructions for all garments (to include MSS)
Before laundering make sure all zippers are zipped and all snaps and hooks are fastened. Tie draw cords together.
For MSS use front load washing machine
Machine launder using delicate/gentle fabric cycle or by hand.
Use lukewarm water (90º F) and cold water laundry detergent
Rinse in clean cold water.
Dry in tumble dryer. Do not exceed temperatures of 130º F as degradation of component materials will occur. For Level VI set on permanent press.
Avoid over drying.
To drip dry place on a rust proof hanger
Do not press Do not starch Do not use fabric softeners Do not bleach.
