The Marmot Men's WarmCube Active Novus Jacket is a warm and breathable jacket for active winter adventure. You're outside, your hike is physically exerting, but it's still cold out. The featherless synthetic insulation in this jacket has been packed into internal cubes that trap lots of heat. It also allows air to circulate, allowing that trapped heat to still be effective when you pause for a rest. Lightweight, packable, and layered as necessary.
