The North Face Women's Freedom Stretch Pants - Comfortable Hiking & Travel Pants for Outdoor Adventures (Standard & Plus Sizes Available) - Perfect for Camping, Trekking and Everyday Wear

This is a double layer, but it is still thin. The lining makes it so u have to wear a base layer or it will be very cold inside to the touch. I did not wear as it was way to small for me, so I can't speak to the functionality. The packaging inside the box was already opened when I recieved it.
