"DRY DOWN really elevates our down insulation jackets to new heights. Simply with a coat of PFC-free water-repellent finish that doesn't add any weight, you can stay warmer and more comfortable in your DRY DOWN jackets, even when the weather turns wet and unpredictable."

How the technology works
We love down for its lightweight feel and exceptional insulation, however, traditional down loses its loft and warmth when it gets wet – even from perspiration. That’s why we've developed DRY DOWN.
Using a Nikwax PFC-free water-repellent finish, DRY DOWN retains warmth and loft for up to seven days of water exposure. Designed in the Swiss Alps and tested by athletes, DRY DOWN is developed with damp, unpredictable weather in mind – making it perfect for ski tours, multi-day hikes, and challenging alpine conditions. What's more, the down is responsibly sourced and RDS-certified to protect animal welfare.
With DRY DOWN, you can count on high-performance warmth and comfort, all while packing light.
