The Fusion 40-degree sleeping bag is an innovative, zipperless hybrid design featuring a waterproof down-filled top and synthetic TechLoft Micro-filled bottom. Our TechLoft Micro insulation consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. It is an ultra-lightweight insulation that has a tremendous weight-to-warmth ratio. The Fusion uses RDS certified 600-fill waterproof down which adds water resistance and prevents the down from clumping. The 380T 20D nylon shell and liner fabric provide a soft and comfortable feel.

This unique, zipperless bag design allows for ultimate comfort and ease of use. The quilted down top is unattached on three sides allowing it to fold open for more freedom, or tuck in for added warmth. An easy toggle system eliminates gaps when the quilted top is tucked in — keeping the heat locked in. The Fusion also offers an adjustable drawstring hood for colder nights at camp. The 82" length accommodates most people. The Fusion is the perfect light-weight, backpacking sleeping bag for mild-weather camping.
