Fans, customers, and dealers alike have been asking Western Mountaineering about quilts for years and finally their answer is here: the AstraLite & NanoLite. These quilts are a thru-hikers dream. Constructed with our 12 denier nylon ExtremeLite shell fabric, a 10D tafetta liner and our world famous 850+ fill down they’ve created products with stellar weight savings.

SKU: N/A Categories: , , Tags: , ,

Western Mountaineering top quilts are 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 AstraLite is hoodless, it is important to pack adequate head insulation. AstraLite users should consider bringing a hooded puffy along if temperatures are likely to dip below freezing.

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.

The AstraLite come in two lengths; the 5’8″ version is design for people at or below 6’0″ tall and the 6’4″ version is design for people between 6’0″ and 6’6″.
