Alpinists and thru-hikers reduce weight and maximize performance with a system approach to insulation. The Navis sleeping bag is designed specifically for backcountry ounce counters who want to save weight by wearing their insulated jacket at night. Sewn-through construction in the upper half of the bag layers easily over a belay parka or a lightweight pullover. The Navis sleeping bag performs in a wide range of temperatures, from 25F to 45F (-4C to 7C), depending on the jacket it's combined with.

Therm-A-Rest Sleeping Bags System Solution

Sleeping pad not included
The System Solution
Therm-A-Rest (TAR) sees your sleeping bag as part of a larger, integrated system. The key components, your bag and mattress, must work together to provide comfort and warmth. Sliding off your mattress or shifting the loft in your sleeping bag can cause you to lose thirty percent of your total warmth, not to mention hours of sleep. This insight led TAR to develop innovative new technology that creates a link between your bag and mattress, and provides a dramatically better sleep experience. TAR's system solution also allows their bags to be among the lightest on the market, making them an ideal choice for anyone in search of warmer, more restful nights and lighter, more productive days in the backcountry.

Sleep Securely
The key to TAR's System Solution is the patent-pending SynergyLink Connectors, which make sure you stay on your pad, and stay warm all night. 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. Therm-a-Rest blankets use the included loop kit to achieve the same performance. SynergyLink Connectors are designed to fit any mattress up to 25 inches (63 cm) wide.

Sleep Warmer
Zoned Insulation puts loft where it helps you the most. Fill is concentrated in the top of your sleeping bag, where it traps rising warm air. The bottom of the bag is insulated by your mattress and requires considerably less fill to keep you warm. Therm-A-Rest's construction is based on thermal mapping and supported by over forty years of sleep research.

Move Freely
Therm-a-Rest sleeping bags are designed with extra room in the torso to allow your shoulders, elbows and hips to move freely. At the head and foot the fit is closer, keeping you warm and decreasing overall weight. More than 70% of people are side sleepers. The Efficient Comfort design is ideal for side sleepers or anyone who wants more freedom of movement without adding extra weight to their pack. Try a bag and experience the difference.
