Sea to Summit Liners Editorial Review
The Sea to Summit Reactor Insulated Sleeping Bag Liner is a lightweight and comfortable option for those looking to add extra warmth to their sleep system. The liner is made of 100% polyester and is machine washable. It does not have a side zipper and is designed to be used as a body sock. The liner adds about 10 to 15 degrees of warmth to a sleeping bag and can also be used on its own in warm weather. Based on customer feedback, the liner does work well in cold temperatures when paired with a warm sleeping bag or quilt. However, some customers found the liner to be too small and uncomfortable, while others felt that it did not provide enough warmth on its own. Overall, the Sea to Summit Reactor Insulated Sleeping Bag Liner is a useful addition to anyone's sleep system, but buyers should make sure to choose the right size and keep in mind that it works best when used to extend the comfort range of a sleeping bag, not as a safety measure.
