New model for this year (Do not check this option if this model was listed as new in last year's Gear Guide)The three-season Saros is ideal for mountaineers, backcountry hikers, and weekend warriors who seek lightweight, warm, and hydrophobic protection. Rated for 20°F and insulated with Therm-a-Rest’s own
eraLoftTM, a proprietary short-staple synthetic insulation in a shingle construction, the Saros provides all-weather performance in a myriad of conditions.
Patent-pending SynergyLink 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 sides, where less fill is required to hold warmth. Loft is eliminated in the back of the bag, where a mattress provides full 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.
