KLÄTTERMUSEN Fjörm 18L £149

Fully waterproof rucksacks are a niche market, but if you’re a genuine “I will walk even if it’s razzing down” kind of walker – or you like to combine walking and paddling or kayaking – they make a lot of sense. The Fjörm is fully waterproof, with fully taped seams plus an additional lid for extra protection and a clever super-lightweight bungee cord chest strap. klattermusen.com
