A sleeping bag liner is a great way to insulate yourself from scratchy bed sheet or even to keep warm on a flight. You can't beat the feeling of silk sheets, so having the Sea to Summit Premium Silk Travel Liner means that you'll be sleeping in comfort no matter where you end up. Silk is a great fabric for a liner because it dries quickly, is incredibly lightweight, and the ripstop weave lends durability to the material for a long usable life. An added bonus is the stretch panels along the sides, allowing you to move when you turn, roll or curl up at night. The Traveller edition includes a pillow pocket to the keep you pillow in place or to be stuffed with extra clothes.
