Western Mountaineering's Tioga silk sleep liner is a light and comfy option as a bag liner or sleep sack for travel. The silk is soft yet woven with ample density to protect you from questionable bedding during your travels. The fabric wont catch when used inside your bag or under some blankets in the loft of a winter cabin. It packs small enough to take anywhere and using it will keep your bag's lining cleaner on extended backcountry outings.
