The Arc'teryx Cerium SL delivers lightweight insulation without compromise. Engineered with 850-fill down and a minimalist design, this jacket excels in alpine environments where weight matters. The Arato™ nylon shell sheds moisture while maintaining breathability, and strategic baffling prevents down migration. Compressible enough for pack integration yet warm enough for layering in cold conditions, it's built for climbers and mountaineers who demand performance at elevation.
