Recycled synthetic down jacket, ultralight and compact, which seeks to provide an insulation/weight ratio equivalent to traditional down jackets, but being animal-free and of recycled origin. Designed for mountaineering FAST&LIGHT and mountain skiing, even in humid conditions. It has been made using two extremely light and resistant Gelanots® fabrics, strategically located in search of greater resistance to friction or lightness. Its high insulating capacity is provided by the 100% recycled synthetic filling of Thermore® Ecodown® Fibers together with High Loft panels combined by thermographic techniques in areas where greater insulation (chest, back, shoulders) or maneuverability (forearms, hood) is required.

It offers very high thermal resistance (even in wet conditions), wind resistance, water resistance (free of PFCs), foldability, breathability in an extremely light weight of 330 grams, more than responding to the vision of its creator, Oswaldo Rivera, a step beyond in FAST&LIGHT design: lightness, high functionality and sustainability.
