The Berghaus Ramche Down 2.0 Jacket definitely sets the standards when it comes to ultra-light and extremely warm down jackets for mountaineers! Thanks to its perfect balance of warmth and weight, the Ramche Down 2.0 is ideal for beginning and expert alpine climbs alike. The jacket is engineered to deliver precise heat zones through body-mapping technology and does just that, even in the iciest of conditions. Plus, the so-called offset battle construction serves to eliminate cold spots, keeping you and your body's core warm! The hydrophobic goose down by Nikwax with 850 fill power in the original Ramche has now been upgraded: the PFC-free hydrophobic 90/10 down is water repellent for up to 16 hours and is RDS certified, which guarantees the ethical sourcing of down products. In addition to this impressive insulation technology, there is also a reflective mesh over the body of the jacket, providing up to 10% more thermal efficiency. The exceptionally tough XO Shell completes the package: The material is about 200% stronger than other fabric with a similar weight, making it the perfect choice for your mountain adventures!
