The Trial series is a professional line of expedition-trekking backpacks available in 55L, 75L, and 90L capacities, specifically engineered for extreme expeditions, high-altitude climbing, and mountain trekking. These technical packs are designed to provide maximum reliability and comfort during long-duration mountain activities where load stability and gear accessibility are critical. Whether navigating technical ascents or extended wilderness traverses, the Trial series offers the necessary volume and structural integrity.
Durability is a core feature of the Trial series, constructed with 600D Polyester Rip Stop for the main body and heavily reinforced with 1680D Nylon FTX TM on the bottom panel. This heavy-duty fabric combination ensures superior resistance to abrasion and punctures in harsh environments. Topped off with world-class YKK® zippers and specialized Duraflex® hardware, these backpacks are built to withstand the rigors of extreme outdoor conditions.
Every detail of the Trial series is optimized for organization and functionality in the field. The packs feature a dual-access system with a zippered bottom entry and internal divider, a removable top lid with multiple compartments, and volume-adjustable front and side pockets. For technical gear management, the design includes ice tool loops, trekking pole attachments, and an elastic cord system on the front panel. A waterproof rain cover is tucked away in a dedicated zippered pocket, while the internal Н2О system with a specialized valve ensures consistent hydration during treks.
V-VAR Carry System
This advanced suspension system (Vertical Variable Adjustment Ridge) is designed for superior load management through innovative frame construction. It features dual vertical aluminum stays integrated with a rigid frame sheet, allowing for direct load transfer from the spine to the hip belt. The height-adjustable anatomical shoulder harness and the central buckle adjustment system allow for a precise fit, while horizontal curved plates increase head mobility during technical climbs.
