This brilliant rucksack was a replacement for my trusty R20, which I managed to destroy after hitting a deer in a big off on the way home from work. It features Kriega’s genius parachute-style Quadloc harness system, which effectively takes the weight off your shoulders and spreads it evenly across your chest, and a well-padded back and shoulder straps. It really works. The main compartment is 25 litres, hence the name, and it’s plenty big enough to easily swallow jeans, trainers, spare visor and gloves, waterproofs and all my other junk on the daily commute. The compartment itself is accessed via a sturdy zip at the top of the bag, and once open there’s a small, waterproof pouch, ideal for storing a wallet, and a laptop pocket (it’s big enough for a 15in MacBook Pro). It’s also plenty big enough to carry everything you’ll need for a long-weekend away. And if that's not enough, the clever design means you can easily attach one of Kriega's tailbacks to the rucksack, increasing capacity by five or 10 litres. The bag itself is made from durable, rip-stop nylon and Cordura, and on the outer there’s another zipped pocket with a reflective patch, which is perfect for carrying a spare set of gloves and a sidestand puck. The harness makes it difficult to access your wallet when filling up with petrol, but Kriega have solved this with the addition of the Kube, a useful pocket which velcros to the shoulder strap. I’ve had it some four years now, used it pretty much everyday, in all weathers, and after some 60,000 miles of use and abuse it still looks like new. It comes with Kriega’s 10-year guarantee. Recommended.
