Why you will like it
- 100% box baffle construction for extremely cold conditions.
- Ultralight 3-layer shell fabric for maximized weather protection and durability.
- Sophisticated 8000-meter pants with an impressive warmth-to-weight-ratio.
The Guide Expedition Down Pants are the final result of extensive technical development, superior craftsmanship, meticulous lab testing, and above all grueling real-world experiences.

In collaboration with down experts in the US and fabric innovators in Japan, we designed these sophisticated expedition pants to withstand extended periods of extreme temperatures on the world’s highest peaks and in desolate arctic regions. They are among the most technically complex garments we have ever made.

They are built using an advanced box baffle construction, and filled with generous amounts of responsibly sourced premium 900 fill power goose down that is RDS-certified, blue sign-certified and 100% traceable. The Dermizax®Ultralight 3-layer rip-stop hardshell fabric provides extreme weather protection and lightweight durability. They have an oversized expedition fit with an adjustable waist, two oversized cargo pockets and an innovative drop-seat function (when you have to go you have to go). At only 904g in size medium, with a 267,4g down fill, they have an impressive warmth-to-weight-ratio. Very few down pants on the market that can match their performance.

Please note: The pants will be extremely compressed on delivery. They will need 72 hours minimum to regain their shape and to loft completely after shipping.
