Bring a little extra comfort to your sleeping bag with this lightweight thermal mesh liner. These warm up sheets are also great to use in the summer if you have an extra warm bag and you think you might get to hot. Just unzip your bag and use the warm up sheet. These sheets are also great for cooler nights with bags not rated for the cold.
