The Blackfell 20 Litre pack with a hydration reservoir is our mini-expedition rucksack for day trips into the hills or mountains. It's engineered to carry all your gear and essential liquid with complete ease. It features padded air mesh back panels for comfort and protection as you move. 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. We included a handy bungee strap on the front in case you need extra storage and quick access mesh pockets on the side. It uses tough wearing ripstop fabric to withstand bumps and snagging, and features a reflective trim helps to help keep you seen on early rises and late finishes.
