Mammut Eiger Nordwand Light Insulated down jacket

Lightweight, low-volume insulation. Tested by athletes as part of our Eiger Nordwand range, this packable jacket (with included stuff sack) is a great layering piece. Mammut´s 900-cuin-fill-power DRY DOWN insulation offers outstanding warmth-to-weight ratio, even when damp. Strategically placed G-LOFT® ECO EVOX synthetic insulation locks heat into areas most exposed to moisture. The recycled 20D Pertex® Quantum downproof outer fabric enhances thermal performance, while a DWR treatment and Diamond Fuse technology boost weatherproofness and durability. With repairable features, the Eiger Nordwand Light Down IN Hooded Jacket is versatile, reliable choice for many seasons to come.

Pertex® Quantum®:
- Pertex® Quantum uses a tightly woven structure to create a lightweight, soft fabric that offers maximum insulation.

PFC-free DWR:
- Perfluorinated compounds (PFCs) are often used for waterproofing but are practically non-biodegradable. Mammut is committed to replacing non-biodegradable fabric treatments with more sustainable high-performance alternatives.

Recycled:
- This product contains recycled materials with uncompromised performance and functionality. Choosing recycled materials reduces the use of virgin resources and helps promote a more circular economy.

- On multi-day adventures or other activities with a lot of equipment, space in the backpack is at a premium. Similarly, for those aiming to travel fast and light, packability is essential. This factor may be less relevant if protection and durability are the top priorities.
- We design every product with performance in mind. That´s why weight, in combination with functionality, always plays a major role. The lighter the style, the freer and more agile you can move. The more durable and dense it is, the more protection it offers.
- For your garment to last you a long time despite plenty of abrasion or rock contact, it has to be hard-wearing. Do you weigh every gram and define absolute freedom of movement as the most important characteristic Then less abrasion-resistant, lighter clothing can be an advantage.
- Windproof clothing keeps you from getting cold on breezy peaks or blustery trails and minimizes the wind chill effect, which is your body´s heat loss accelerated by wind. Pay special attention to this factor when your pace is high and conditions are cool and windy.
- Down, synthetic fibers, wool - they are all tasked with storing heat and protecting against cold. The warming layer can vary in weight, breathability and packability. Exactly how warm depends on the intensity of the sport, the outside temperature and the space in your pack.
- Even when every gram counts on the trail, you need clothing that provides reliable warmth. A high warmth-to-weight ratio means lots of warmth with little weight.
