The Agner Hybrid Down Jacket is a hybrid insulation layer for alpine climbing where high-intensity leads are often followed by long, cold belay duty. Salewa’s designers use body mapping to carefully match the design and materials to the body’s ability to insulate and manage both flash cooling during static periods and overheating during activity. The resulting hybrid construction provides warmth only where you need it and does away with unnecessary insulation. High-loft 90/10, 750 fill power down is placed only at the torso, back and shoulders, while stretch, lightweight rock-resistant softshell is used in the areas where climbers need more breathability and freedom of movement. However, the real secret behind the Agner Hybrid Down Jacket is that its down chambers are not stitched but bonded, and have laser cut perforations between the baffles to allow active-venting airflow so that excess body heat can escape. The result is a super high warmth-to-weight ratio and super small packability. The Agner Hybrid Down Jacket also features a lightweight under-the-helmet hood for additional protection from wind chill. The lower arms, side panels, hem section and hood are all made of Salewa’s new-generation, rock-resistant, 4-way stretch Durastretch softshell fabric, to provide the breathability and freedom of movement you need when climbing.
