Our Editor Says "The BTR hi vis rucksack cover has been along time in development.  We tried lots of strap combinations & pulled (& broke!) alot of straps in the process of finding the best ones available.  We love the result though.  It is a sturdy, waterproof, thick & very durable rucksack cover."

Great product

Having used similar types of backpack covers in the past which had a lot of trouble staying on, either with straps that broke or elastic round the edge that didn't really hold it, I was drawn to this with the velcro straps. After a few years of use, I've bought a replacement as the mesh pocket, where I stuffed all my cycling stuff (including bungy straps) was beginning to rip (mainly caused by bungy strap hooks getting caught in it). The rest of the cover is still in good condition. I use it to cover my backpack on the rack of my bike, and it has been very effective in keeping the rain out, even in some extreme downpours. The high-vis nature of it is also great. I would also say BTR's customer service was great in dealing in sorting things out when I ordered the wrong size. I also find that passing the vertical strap between the two horizontal straps keeps it from hanging right off if you need to get into the top of your backpack, or if the velcro at the top becomes detached.

Feeling Safer

I had been looking for a reflective cycling rucksack, most are very expensive, plus we had a perfectly good small rucksack we were using. This highly reflective and easy to use bright cover was the perfect cost effective solution. Added to the safety aspect our small rucksack now has a fully waterproof cover. At this gloomy time of year I am carrying the rucksack mostly empty just for the extra visibility.

Be seen

Easy to use, the smaller of the sizes is still abit too big for my 20lt bag, but the vertical and horizontal Velcro straps see to any fine tuning adjustments and it fits well and feels very secure. It’s my first winter riding on the roads in the dark and I bought this more for confidence and being seen than water resistance, but it did the job in Yorkshire drizzle.

Does exactly what it says on the tin!

Great bit of kit. Glows under headlights, bright colour during day time. Sets of straps on both sides with a decent length of velcro on both which means that its very adjustable, so if you have the big size (for when its a big bag or multiple bags on the rack kinda day), this thing can be adjusted to fit over it all. For info for others, we are mostly using the wrapped over luggage attached onto a front rack, rather than over a backpack in the normal location. Not tested the waterproof element yet, but fabric looks good quality. We're really pleased with it, and its made an excellent (and reasonably priced) addition to our winter 'commuting with kid' kit stash. Would highly recommend.
