Materials and Weather Readiness

Crafted with bluesign^® approved nylon and a PFC-free DWR finish, the Ariel 55L blends responsible materials with practical weather resistance. A raincover is included for sudden showers, helping protect gear from drizzle and mist on exposed ridgelines.

Backpanel, Fit, and Load Comfort

An injection-molded backpanel creates breathable contact with ventilation channels, helping air move along your spine while keeping the load stable. The mesh-covered foam lumbar area provides soft, comfortable support, and the extendible hipbelt plus Crossbody ErgoPull design helps pull weight toward the lumbar for balanced carry.
