Mammut Eiger Nordwand Light Down IN Hooded Jacket

You finally stop moving, and the cold catches up fast. We like a warm layer that comes out of the pack without taking up half the space inside it.

Consider Another Option If

You need a waterproof outer layer or heavier insulation for long periods of inactivity in extreme cold.

• Alpine climbing and mountaineering
• Cold-weather ski touring
• Cold belays and summit breaks
• Lightweight layering on technical routes

• 900-fill DRY DOWN: High warmth-to-weight ratio
• Targeted G-LOFT ECO EVOX: Insulates moisture-prone zones
• Pertex Diamond Fuse: Resists abrasion
• Helmet-compatible hood: Adds coverage
• Harness-compatible pockets: Keep gear accessible
• Packable construction: Stows in the included sack

Can I wear this jacket under a hardshell?

Yes. Its compact construction allows layering beneath a compatible shell.

Is this jacket waterproof?

No. Its water-repellent treatment does not replace a waterproof outer layer.

How does the down handle damp conditions?

Hydrophobic DRY DOWN helps retain insulating performance when damp; avoid prolonged wet exposure.
