Aptly named, the Sassy Beast fuses bold style and gritty performance. Impermeable yet breathable, the waterproof construction keeps out winter's deepest powder and spring's wettest snow without upsetting our microclimate underneath. On demanding bootpacks and warmer days, we open the mesh-lined vents for even more airflow, while the insulation's touch of warmth keeps us cozy through those still moments taking in the view before the drop.
