Western Mountaineering Extremelite Fabrics
For the Extremelite sleeping bag line, Western Mountaineering worked with suppliers to develop extremely high thread count fabrics with ultra lightweight yarns, never before seen in the sleeping bag market. The fabrics are constructed from yarns that are 20 denier or finer with up to a 380 thread count. These materials weigh less than one ounce/square yard, and allow the lightest weight down products available. The Extremelite series features seven bags designed for special applications where volume and weight are critical factors.
