The soft and cozy Synergy Sleeping Bag Liner adds warmth, comfort and years of life to any sleeping bag. Contributing up to 5F/3C degrees of warmth to your sleeping system, the soft, stretch-knit polyester also serves as a protective barrier to your expensive sleeping bag’s materials, absorbing the sweat and oils that would otherwise go directly into your bag and decrease its loft. Now, instead of washing and drying your entire bag or allowing that grime to clump up the insulation, all you have to do is remove the liner and toss it in the washing machine.

Carefully shaped to fit in your favorite mummy bag. Super comfortable, 100% recycled stretch-knit fabric and flatlock perimeter seams create a ‘baselayer’ inside your sleeping bag; fits bags up to 6’6” and weighs just 21.1oz (342g). Adds up to 5F/3C degrees of warmth to any sleep system, verified by tests in our in-house cold chamber. Protects fabric and insulation from dirt and body oils, minimizing wash cycles and extending the life of your bag. The Synergy Sleeping Bag Liner adds warmth, a soft next-to-skin layer and easily washable protection to any sleeping bag.
