Rab Syclon XP 40

Rab Syclon XP 40 stands out as an award-winning, ultralight and fully waterproof hiking backpack built for fast mountain days and long-distance routes. The roll-top pack design adapts to changing loads, while the ventilated Aerofit back system hugs the body for stable carry over many hours.
