A lightweight down jacket for high-output winter missions.

The Ultra Down Liner Jacket is the right choice if you:

• Need a versatile down jacket for alpine adventures
• Want premium insulation that breathes during high-intensity activity
• Look for a jacket that doubles as a warming mid layer in colder conditions

The Ultra Down Liner Jacket is designed for active mountaineering and expeditions where warmth, breathability, and packability matter most. Filled with certified premium down and crafted with a ripstop woven fabric for extra durability, this jacket delivers reliable warmth while remaining exceptionally light. It features excellent breathability, making it ideal as a first or second mid layer under a shell, or as an outer jacket when the weather is less demanding. All zips are durable YKK®, including the four functional pockets and the two-way front zip. The helmet-compatible, adjustable hood adds to the jacket’s versatility. An elastic binding at the hem ensures a snug fit, and when not in use, the jacket packs neatly into its included stow bag. Lightweight, durable, and breathable – the Ultra Down Liner Jacket is the perfect choice for layering on demanding alpine pursuits or wearing on its own in milder climates.
