The Hyperlite Mountain Gear Northrim 55 is a 55-litre roll-top pack built from Dyneema/DCF (Dyneema Composite Fabric) with 375D Dyneema Woven Composite on the bottom, external pockets and hip belt pockets, weighing 996 g, aimed at multi-day trekking and mountaineering trips off established trails rather than groomed paths. Removable aluminium stays and a foam back panel give it real load-carrying structure while keeping the option to strip the frame for shorter, lighter outings. A padded hip belt with its own pockets and a chest strap help transfer weight off the shoulders on longer carries.
Three front pockets and a rolltop main closure give quick access to layers and snacks without opening the full pack, and a single ice axe loop signals the mountaineering-leaning intended use alongside general multi-day trekking. At 996 g for a 55-litre pack with a removable frame, hip belt pockets and a dedicated ice axe attachment, the weight reflects genuine load-carrying structure rather than a minimalist frameless build.
This suits hikers heading off-trail into rougher mountain terrain who want DCF's water resistance and durability along with real load support — not hikers on maintained trails who'd be better served by a simpler, frameless pack.
