Anti-Gravity Nylon is an ultralight fabric that enhances the performance and reduces the bulk and weight of down sleeping bags. The exceptionally low weight of Anti-Gravity Nylon allows down to loft to its full potential without restriction; meaning more warmth with less down, less weight, less bulk.
