By doing an Overfill, we add additional down throughout your sleeping bag. This increases the warmth of the bag by around 5 degrees. Overfills also improve loft duration. During extended use down becomes clumped with moisture, dirt, and oils. An overfill prevents this by adding more fluff.

*This product is an add-on to a Western Mountaineering sleeping bag, and cannot be purchased on it's own.
