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.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Jack Wolfskin Allspark Daypack is a good looking bag that can remain understated when needed then highly visible when the lights are turned on. It sits comfortably on the back and has a commuter-friendly 20L capacity too. However, it would be good if the smaller internal pockets were a bit bigger and if it came with its own power bank.

One of the major drawbacks of commuting by bike at this time of the year is that some of your riding will be in the dark. The Allspark Daypack aims to help out here by offering excellent visibility without looking like a high-vis bag.

It does this through light strips that run across the bag. This means that when you're riding at night it doesn't matter if a vehicle light hits your bag to make sure you're seen, as the bag itself is the source of light – so other road users will always see it.

The light strips are fairly discreet when not turned on and unless they are plugged in you are unlikely to know what they are. When turned on they offer an impressive amount of visibility, to the extent that I would be confident to not run a rear light when using the bag.

Operating the lights is fairly basic: you plug them into a power bank and they will run until the power bank runs out or you unplug the USB cable. It's worth noting that the bag does not come with a power bank itself, you need to supply your own. Both the power bank and the USB it plugs into sit within a pocket at the top of the bag between the two straps; it's also big enough to house a phone and wallet without any issues.

One of the things Jack Wolfskin advertises is that the lights help you find things inside the bag in the dark. Although it does give you a little extra light, this is just at the top of the bag and not in the darkest areas that are hardest to see, so the lights don't really help that much.

Away from the high-tech elements of the bag, it has one main compartment and two small pockets inside, in addition to a laptop pocket built into the back padding, and a phone pocket on the side. I found this was adequate for most of my commuting kit, and given the relative flexibility that comes from the semi-roll top there's enough leeway to fit most objects that you're likely to need during the day. I did think the inner pockets could do with being larger, to help with separating out your kit; their size limits this a little.

The rucksack sits well on the back, with comfortable and relatively good ventilation both across the back and in the straps. I didn't have the opportunity to test this out in high heat, but from what testing I've done I would be confident that it'll be comfortable for most riding conditions – and if it's not, I'll update.

Being a semi-roll top means it can only be rolled once – any more than that and you are unable to close it because of the buckle. The way the edges folding in easily along scores in the fabric is neat, meaning the edges fold in for uniformity and protection. The clip is innovative too, simply pushing into the buckle to hold it, and pulling upwards (a little like a plane seatbelt) to release.

In terms of weatherproofing the bag will withstand a light shower, but anything more and the Armatech Plus 600D does let some water through. For some reason, the Jack Wolfskin Neuron is made of the same material and comes with a rain cover, but this one doesn't.

An rrp of £115 seems fairly steep at first glance, although the innovative elements like the LEDs and closure system go some way to justifying it. It's £15 less than the Evoc Commuter 18L Backpack, which doesn't have the LEDS and is smaller, though the Evoc has better internal organisation and waterproofing. Chrome's BLCKCHRM 22X Lako 3 Way Tote is £5 less, but a much more basic design.

Overall, there's plenty to like about this bag – the LEDs are a great addition, it's comfortable on the back, and has decent amounts of storage – but I think there are a couple of things that could be improved upon, especially for the money, such as the lack of a power bank and rain cover, and the size of the internal pockets.

It performs fairly well: it sits comfortably on the shoulders and is large enough to hold everything I needed. The only downsides are the size of the internal pockets and lack of waterproof cover.

The LED lights work really well, they're easy to use, bright enough to make sure you're seen and don't make the bag look odd when not in use.

Tell us what you particularly disliked about the product

The internal pockets could be bigger to be a little more useful and allow kit to be properly organised.
