Big Agnes Liner

Being cold while sleeping in the wild is not a good time—avoid the midnight chills with the Big Agnes Sleeping Bag Liner. This camping companion comes in three different materials—merino wool, Polartec fleece, or classic cotton—to fit a variety of needs while sleeping sound in the great outdoors. The merino wool liner offers extra warmth and aids temperature regulation, the fleece variety traps heat to eliminate the cold on an icy excursion, and the cotton option provides a natural softness and helps to keep our sleeping bag feeling clean. All varieties come with a stuff sack for convenient packing, a cinch-up hood to prevent heat from escaping, and hooks at the head and foot that connect to liner loops inside our favorite sleeping bags.
