Eigerjoch Pro IN Hooded Jacket - Men's

Pertex Quantum Pro is a lightweight and durable fabric that is both windproof and water-resistant. This makes it perfect for outdoor activities in harsh weather conditions, as it helps protect you from the elements while remaining easy to pack and carry.

A Durable Water Repellent (DWR) finish causes water to bead up and roll off the fabric instead of soaking in. This treatment keeps you dry during unexpected rain or wet conditions, making it essential for outdoor clothing designed for activities like hiking or climbing.

An 850-fill down indicates a high-quality insulation material that provides excellent warmth without adding significant weight. The higher the fill power, the better the insulation, meaning you can stay warm in cold conditions without feeling bulky.

PrimaLoft Gold Luxe is a synthetic insulation that mimics the warmth and compressibility of down while being water-resistant. It offers superior performance in extreme conditions, making it a great alternative for those who prefer synthetic materials or need insulation that performs well in wet environments.

High Reach Technology is designed to keep the jacket's hem tucked under a harness during activities like climbing. This feature prevents cold air from entering and ensures that you stay warm and comfortable while moving, making it essential for serious outdoor enthusiasts.

Yes, both Pertex Quantum Pro fabric and PrimaLoft Gold Luxe insulation are engineered for extreme weather. The combination of windproof, water-resistant materials and high-quality insulation ensures that you stay warm and dry, making them suitable for mountaineering and alpine climbing.
