Men's Filament Pullover and Women's Filament Jacket

Featuring an incredible warmth-to-weight ratio, the ultra-lightweight Men’s Filament Pullover™ and Women’s Filament Jacket™ are never-leave-it-behind down-insulated layers. Useful as fall belay jackets on its own or as insulation under a ski jacket, the Filament cuts the chill when worn alone in cool weather and holds in the heat as a mid-layer in truly nasty conditions.


The super-packable, DWR-treated 10D Pertex® Quantum fabric sheds moisture, further increasing the versatility of this featherweight, compressible, year-round down pullover.
