Never get a cold seat againSuper-light and ultra-warm layering pants for use under a shell on colder days. Filled with unrivalled 1000 fill power down, this unique — and once experimental — product has become one of our most popular insulation garments.
Why you will like it
- The only 1000 fill power down pants on the market.
- Designed for use with outer layers in extreme conditions.
- Full-length side zippers for easy on-and-off.
When launching this experimental product, we could never have foreseen how popular they would become, selling out repeatedly after each re-stock. Apparently there were more than us in need of super-light and ultra-warm insulation pants for colder days.
The 1000 fill power platinum down is unique in its ability to insulate, but no-one has been crazy enough to ever use it for a pair of pants — until now. The sensation of warmth is immediate when you put them on. The down is also treated for water resistance which makes it more durable, while keeping you warm and dry even in the wet.
The shell material is a Japanese ultra-lightweight DWR-treated 34 g/m2 ripstop nylon. The side zippers makes it possible to put them on and take them off them without removing your shell pants.
