Jump to: Our Verdict / Features / Specifications

Built for distance, designed for load, and comfortable enough to keep going—this is a serious pack for serious mileage.

Rab says: 

Our definitive pack for exploring far-flung regions where self-sufficiency is key, this 65L backpack is geared up for serious multi-day adventures, from long distance trekking to shorter expedition use. It’s loaded with storage features that have been strategically chosen to provide maximum utility for minimum weight, focusing on the elements you really need on remote journeys. With a highly cushioning wraparound harness and an adjustable V-TRAX™ back system, it supports heavy gear with ease and offers comfort that endures over distance and extended periods on the trail.

Our Verdict

The Rab Hyperion 65 shines on multi-day routes where carrying a bit more is non-negotiable. Weighing in at 2,458g, it’s not chasing ultralight status, but Rab has prioritised durability and comfort over weight savings—and it shows.

The V-TRAX carry system is refreshingly straightforward. A Velcro-based adjustment lets you slide the harness to match your torso length, and once it’s set, it stays locked in. The back panel offers enough breathability for sweaty ascents, while the padding strikes a nice balance: supportive without feeling bulky.

Storage is intuitive and practical. Dual access—top and lower zipped entry—with an internal divider makes packing and unpacking a breeze. The hipbelt pockets are genuinely usable, roomy enough for snacks or a phone, and the side pockets easily swallow 1L bottles. The front pocket, while more protected than your typical mesh pouch, isn’t as quick to access—a trade-off between convenience and durability that, honestly, sums up the bag’s design philosophy.

Internal compression straps help stabilise the load, and a rain cover is stashed underneath for when the weather turns.

In short, the Hyperion 65 is built to carry weight without complaint. Fully loaded, it doesn’t rattle or sag, and it feels like a pack made for the long haul—especially when reliability matters more than bells and whistles. This is the one I’d grab for remote treks, where gear failure isn’t an option.
