The North Face Flight Sleeping Bag:
An ideal choice for minimalists and outdoor enthusiasts who like to travel light while remaining comfortable, the lightweight Flight is a synthetic-fill sleeping bag rated to 35F (2 C). It's filled with Polarguard® Delta insulation, a new innovation that offers the same performance as Polarguard® 3D insulation, but with 10% greater loft and 12% less weight. This quality insulation is currently only available in sleeping bags from The North Face. If you prefer sleeping under the stars, you'll appreciate the special BottomLine taffeta shell fabric that protects the bag from damage from abrasion and grit. The upper shell features Firestorm iridescent cross-dye shell fabric for wind- and water-resistant performance. An overlapping shingle construction effectively layers the insulation without the cold spots and the insulated chest-level heat trap baffle and forehead comfort tube minimize heat loss through the head opening.
