The hump is a waterproof Hi-Viz cover designed to fit over rucksacks and panniers with 40 litre capacities. Sizing seems pretty universal and fitting couldn’t be simpler (although proved a struggle on some panniers and older hydration packs). Roll the hump over the bag, secure the elastic webbing in a cross formation and pop the press-studs together.
Sometimes covers can ride up, leaving panniers and their contents vulnerable to water and spray. However, the elasticated corners ensure excellent retention without infuriating flapping on blustery rides. Acres of Scotchlite striping add extra visibility to help minimise rider vulnerability when negotiating roundabouts and/or emerging from junctions while the day-glow yellow is suitably assaulting to the eye-especially in low light.
A capacious mesh pocket is ideal for bunches of keys, small carton of milk and other nick-nacks and when on a rucksack makes a great LED mounting point. In most cases, a quick wipe-over with a damp cloth keeps it looking fresh but those of us enjoying a bit of dirt in our diet will be pleased to hear it can be machine washed at 30 degrees. (Remember to put some proofing in with the wash to retain the cover’s water repellency).
When not in use the Hump folds down in to a small package that won't take up much space in your rucksack or bag. Those seeking the last word in illumination will be delighted to know there is also an even more visible version with integral LED piping.
