Mammut Eiger Nordwand Insulated Flex Air jacket

Warm and breathable for high-intensity ascents. Tested by athletes as part of our Eiger Nordwand range, this jacket offers versatile protection as a mid- or outer layer. Quick-drying Polartec® Alpha® Direct Polypropylene insulation provides warmth in harsh conditions while allowing sweat to escape. The 20D Pertex® Quantum Air outer fabric combines breathability with elasticity for freedom of movement during rock and ice verticals. With a durable design and easy-repair features – like a fixable YKK® front zipper slider and a patch kit for on-the-go repairs – the Eiger Nordwand IN Flex Air Hooded Jacket is an efficient, versatile choice for alpine adventures.

Durability:
- 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.

Packability:
- 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.

Quick drying:
- To prevent you from losing heat during a break at the summit, your clothing must wick sweat and moisture away from the skin and allow it to evaporate quickly. The more you sweat during an activity, the more important it is for it to dry quickly and have breathability.

Warmth-to-weight ratio:
- 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.

Lightweight:
- 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.

Windproofing:
- 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.

Technology:

Pertex Quantum Air:
- Pertex Quantum Air was designed to increase air permeability, striking a balance between windproof rating and breathability.

Polartec Alpha:
- Synthetic fabrics used in Polartec Alpha products are incredibly durable and strong. The open structure of the insulating material offers excellent vapor permeability and heat retention.

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.
