Overfill climb ice and snow protection As its name impliesExtra Warmth and Long Term Loft Retention. The Overfill option allows you to add extra down throughout your fully baffled sleeping bag, increasing warmth by approximately 5F. In addition to providing extra insulation, an overfill helps maintain loft over extended use. Over time, down can compress due to moisture, dirt, and body oils, reducing its effectiveness. Adding extra down helps counteract this by improving long term performance and durability.
