The 686 Women's Mesa Insulated Pants combines waterproof Infidry 8K-rated exterior with a lightweight insulation to keep you comfy and dry on or off the slopes. The soft and easy-to-slip-into Nylon taffeta lining on the inside does not restrict movement in any way, and you will never feel over-stuffed or bulky such light and thin is the insulation inside. Critically taped seams prevent snow, water from sneaking in, so you are always dry whether on the streets or up on the mountains. Air-Flo inseam vents with mesh gussets swiftly ditch hot air out without letting snow in. The PJ-Connect jackets-to-paint interface and boot gaiters with lace hooks are a few handy features that will create a formidable layer against snow up on the slopes.
