Description
When the weather turns, the route gets spicier, or the gear starts piling up, the Challenger 28 is the pack you want on your back. Built from sail-grade Ultra 400 and Ultra 200 fabrics, it’s insanely durable, water-resistant to over 200 PSI, and tough enough to drag through rock, snow, and ice season after season.
The design is clean, compact, and made to move—whether you’re linking up alpine ridges, racking up for a mixed line, or chasing a summit on skis. The rolltop expands from 28 to 32 liters, and internal compartments keep layers, gear, and snacks in check. Side-access YKK® zippers, ski carry options, removable ice axe loops, and a helmet holder let you dial it for the day.
The Challenger 28 is built to disappear on your back until the moment you need it—and in that moment, it delivers.
