New model for this year (Do not check this option if this model was listed as new in last year's Gear Guide)The superlight, 1 lb. 5 oz., 750+ fill-power goose down Navis is ideal for alpinists and other minimalists who seek minimalist, lightweight sleep system solutions. Designed to work in partnership with an
insulated jacket—a light down pullover on warm nights or a hooted belay jacket in alpine conditions
• 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. Lightweight, sewn-through construction in the upper half of the bag layers easily over a jacket and provides maximum versatility. Full baffles provide extra warmth from the waist down. Fill is eliminated in the back of the bag, where a mattress provides full insulation from the ground.
• 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.
• The bag comes also comes with a compartmental storage sack, lightweight stuff sack, and stash pocket.
