The Blackfell 45 Litre pack with a hydration reservoir is our mid-size expedition pack for longer trips into the hills or mountains. It's engineered to carry all your gear and essential liquid with complete ease. It features ventilating mesh back panels supported with a steel suspension frame for comfort in wear, without compromising on mobility. The chest harness, hip belt and straps can all be adjusted for a secure fit during more agile parts of your climb. The hydration unit securely zips away and the drinking tube feeds through a retainer for easy access. All your essentials can be neatly organised with water bottle side pockets, front bungee storage cord and a secure zipped lid pocket, which can be extended for an additional 10 litre capacity (ideal for food). We built it from tough wearing ripstop fabric to withstand bumps and snagging, and added a detachable rain cover for those sudden downpours. A reflective trim finish helps to keep you seen on early rises and late finishes.
