Respro Hump Waterproof
"This isn't the most glamorous piece of kit, but it might just save your life," Tony Farrelly says. "It's a luminous cover that fits snugly over your rucksack or panniers to add extra night-time visibility - it's also waterproof so doubles up to keep your gear dry. It's easy to fit and comes with a handy mesh pocket for exra storage or for clipping on lights and, if the weather Gods are on your side, it packs down nice and small."
