Cold Stress Prevention

Cover head with warm material such as cotton, wool, or fleece. Use a fabric face mask when exposed to high winds. In very cold weather, wear a fabric mask or scarf to warm air before you breath it.  Consider the masks and head gear in BNL Stock/Epro described at: Cold Weather Clothing (PDF). 

Dress in layers -  Innermost layer in a fabric that wicks sweat away (such as nylon, polyester, [not cotton]); second layer of warm material such as cotton, wool, or fleece; outer most in water-resistant or waterproof barrier.  Consider the clothing in BNL Stock/Epro described at: Cold Weather Clothing (PDF)

Protect hands with insulated glove or a thin glove inside a heavier wool or fleece lined glove.  Use waterproof gloves when needed.   Consider the thermal gloves in BNL Stock/Epro described at: Gloves - Thermal

Protect feet with two layers of socks- innermost in a fabric that wicks sweat away (such as nylon, polyester, [not cotton]); second layer of warm material such as cotton, wool, or fleece.  Use waterproof footwear when needed.
