  • Product Notes:

    A four-season, extremely lightweight, highly compressible 750+ fill- power goose down bag that’s warm enough to perform in the mountains all year.

    Patent-pending SynergyLinkTM Mattress Connectors—compatible with up to 25-inch-wide sleeping pads—create the most secure mattress connection in the industry. Two flexible fabric bands create a snug fit around almost any mattress, keeping your bag centered and eliminating problems with sliding, twisting and cold spots.

    Thermal-mapped zonal insulation puts loft where it’s needed most. Insulation is concentrated in the top of the sleeping bag, where it traps rising warm air. There is a carefully measured amount of loft at the bottom, where less fill is required to hold warmth and a mattress provides insulation from the ground. Construction is based on thermal mapping and supported by over forty years of sleep research.

    Efficient Comfort design features extra room in the torso to allow shoulders, elbows and hips to move freely. At the head and foot the fit is closer, increasing warmth and decreasing overall weight. The design is ideal for side sleepers or anyone who wants more freedom of movement without adding extra weight to their pack.

    A draft tube and collar are added for maximum heat retention. The sculpted hood and a trapezodial foot box are shaped to fit the body’s natural resting position. The bag comes also comes with snag-free zippers as well as a compartmental storage sack, lightweight stuff sack, and stash pocket.
