850+ FILL POWER EXPEDRY™ HYDROPHOBIC DOWN produced in the U.S. (Allied Feather and Down) with ExpeDRY™ water-resistant treatment to make it hydrophobic.

Katabatic use the highest quality 850+ fill power ExpeDRY™ hydrophobic down. This down has been treated to provide additional resistance to unwanted moisture. In conjunction with highly water-resistant shell materials, ExpeDRY™ provides extra peace of mind, and dries faster than untreated down if it does get wet.

ExpeDRY™ water-resistant down is bluesign® approved, so you can rest assured that it is safe for the environment and human health.

RESPONSIBLY SOURCED DOWN

Like many of our customers, we at Katabatic Gear are concerned with the environmental and animal welfare impact of our products. We are dedicated to a responsibly sourced, and very high quality product, just like our down supplier, Allied Feather and Down. They are certified through both the bluesign® and Responsible Down Standard® programs.

WHY CHOOSE DOWN OVER SYNTHETIC INSULATION?

Down is significantly more compressible, while still offering more generous loft and superior warmth to weight ratio. Additionally, synthetic insulation breaks down faster over the life of the product, losing loft and warmth more quickly than down. As a result, a down-filled product will stay in your kit longer, and out of the landfill, making down a better value and better choice for the environment.
