Extra 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 5°F. 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.

Each sleeping bag has a pre-determined overfill amount, so be sure to select the correct option from the list when ordering. Please note that overfilled bags are not eligible for returns or exchanges, as this is a custom modification.

Below is a list of eligible sleeping bags and the associated cost for this optional upgrade.

To specify your overfill please ensure that you have the proper bag and then select the overfill. If you have questions please contact us prior to ordering.
