GoLite Ultralite 1 Season Down Quilt / Backless Sleeping Bag

This bag is designed for the ultra-light purist on a mission (but also turns out to work great for the fair weather car-camper who demands the finest.)

Materials:
800+ Fill Power Goose Down Renewable Insulation; 15 Denier Nylon Shell; 100% Tier 1 Recycled 22 Denier Polyester Lining Fabric; Microgrid Ripstop Shell; Ripstop Lining; Waterproof-Breathable Pertex® Shield Eco Shoulder and Foot Protection

Our Verdict

This 1 season backless design is an addition to the range, an even lighter version of the Ultra 20 with a single season rating rather than 3 seasons. Backless bags are a good way of reducing weight using the fact that down that you flatten by lying on it is wasted because it won't give anything like its insulation when lofted.

Ideal if you sleep still, but if you move around a lot is a bag then this type of bag can be draughty.

We use premium Eastern European sourced 800+ and 650+ fill power goose down in different products depending on the design and end-use. Down is still the most thermally efficient insulation available, providing more warmth for its weight than any other insulation available. Down is also superior in its drape, comfort, lifespan, and compressibility. All of our down is renewably managed using a hypoallergenic processing technique. 800 Fill Power 800+ fill power down is more compressible and provides a greater loft to weight ratio than 650+ fill power, and is used in our highest performance down products. We specify a 90/10 cluster to feather ratio for optimum loft and recovery. 650 Fill Power Our 650+ fill power down is 15% loftier than the industry standard 550+ fill power down and exhibits excellent compressibility and recovery characteristics. We process it to an 85/15 cluster to feather ratio to emphasize maximum recovery from compression.

Our newly developed Tier 1 recycled polyester and nylon materials test to the same high standards as their conventional, non-recycled alternatives.  We use them because of the massive reductions in energy use and resource consumption required to produce them vs. the virgin, petroleum-based alternatives.  More information can be found under ‘Performance Technology’ within ‘The Meaning of Lite’ section of the GoLite website.
