Respro Hump P15 illuminated backpack cover



A prudent winter upgrade for rucksacks and medium panniers.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The P15 is the deluxe version of Respro’s justly popular hump rucksack cover incorporating not only waterproof materials and retina burning Scotchlite detailing but integrated electro luminescent lighting strips for maximum visibility. However, electrics preclude machine washing so mud mariners would be better served by the less sophisticated model.

Designed to accommodate rucksacks and panniers up to and including 40 litre capacities, it simply slips over the bag before the webbing is clipped together, cross formation using the press-studs. Powered by two AA batteries are sensibly positioned green Lighting strips running parallel so as to ensure complete 360° visibility. Run times of between 45 and 125 hours in static and flashing modes respectively are pretty impressive and on a par with other systems. However, there’s a very low hum in constant mode and the battery pack feels cumbersome compared to Li-Ion and similar technology but at least it means that replacements are readily available anywhere.

The bold logos and chevron detailing coupled with a day-glow orange base are nice contrasts to the classic black, more subtle than the day-glow yellow version but not as visible in murky weather. A capacious mesh pocket gamely swallows keys, multi tools and other little essentials while providing another mounting point for LED lights if so desired. Elasticated corners keep it firmly positioned without any annoying flapping in windy, blustery conditions and while you’d be foolish to attempt river crossings, taped seams ensure heavy downpours simply roll off the cover, keeping the contents bone dry. Electrics rule out popping in the washing machine or even hand washing in soap flakes but periodic wiping with a cloth dipped in mild detergent keeps it looking fresh.

The asking price seems quite steep for a waterproof bag but very reasonable when you are getting a waterproof cover and lighting system all in one.

Tell us how the product performed overall when used for its designed purpose

There's no doubting the hump's prowess-especially for nocturnal riding and while humble AA batteries might seem old hat in the face of Li-On and similar technology, getting replacements in a pinch isn't difficult. Waterproofing is good on a day to day basis but don't be tempted by river crossings, or indeed machine washing because of the electrics. Black version looks classy but not quite so effective in low light as the day glow yellow.
