DESCRIPTION

Expedition weight is an excellent first layer for mountaineering and other activities in extreme cold.. This high-performance thermal wear is a proven value, tested in the toughest conditions. The REI Moisture Transport System® (MTS) draws perspiration away from your skin for maximum dryness and comfort. Fabric is microdenier fleece on the inside for extra softness and comfort next to skin. Brushed on the inside, and smooth on the outside for layering -- layers slide easier over smooth fabric. Machine wash and dry; moisture-wicking ability will not wash out.
