Fans, customers, and dealers alike have been asking Western Mountaineering about quilts for years. Their answer is here: the NanoLite.

This quilts are a thru-hikers dream - constructed with Western Mountaineering's 12 denier nylon ExtremeLite™ shell fabric, a 10D taffeta liner and their world famous 850+ fill down, they’ve created products with stellar weight savings.

The NanoLite top quilt is designed with a set of adjustable and removable pad straps that are compatible with any backpacking sleeping pad. When no gram can go unaccounted for, the straps can also be removed. Other features include a sewn through footbox and an insulated draft yoke with elastic closure for maximum heat retention.

Because the NanoLite is hoodless, it is important to pack adequate head insulation. The NanoLite is designed for above freezing so a beanie and neck gaiter will do. This quilt is designed to be used with an insulated sleeping pad. If you sleeping pad is uninsulated or poorly insulated these products will sleep much colder than intended. Make sure to check the R-value of your pad to ensure it is adequate for 3 season use.
