At road.cc 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.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Cube Helmet Cap Aeroproof Blackline is designed to keep your head and ears warm while riding in colder conditions. It is windproof and sits well underneath the helmet; essentially it does everything it needs to do on a winter ride.
Resembling a scrum cap, the Cube Helmet Cap Aeroproof Blackline is a beanie that sits underneath your helmet, made from 45% polyamid, 42% polyester, and 13% elastan. It is not a cap that you are ever likely to wear without a helmet as it would look slightly strange in isolation.
The material used is flexible and sits well on your head, tight enough that it feels secure, but flexible enough that it does not exert any kind of unpleasant pressure on your forehead or ears. The only thing to watch out for is the stitching at the base when putting it on initially, there were a couple of cracks from the seams when I was stretching it over my head.
The material has been well thought out, being both practical in terms of heat retention and thin enough to not need to adjust your helmet. It is impressively wind resistant, although it's worth noting that the coldest temperature I could test at was around 5 degrees, but I'm confident it could go significantly lower.
The cap effectively covers your ears without putting pressure on them (something that I have found with other helmet caps in the past), while allowing for a decent level of breathability due to the vented panel covering the forehead.
One of the worries that I had with this was the amount of stitching throughout. It has six lines of flat lock, double stitching across the top of the cap that I thought may cause some irritation, but the truth is that I barely noticed them at all.
At £30 the Cube Helmet Cap is expensive. It works well for wind resistance and the thin materials allow it to sit perfectly underneath the helmet. In essence, it is a simple but important piece of cycling gear for winter training. It has been well designed and made, the only problem I could find is the potential weak stitching around the base of the cap, but this is fairly minor.
Is it worth £30? Perhaps, but others can be found at half the price for what is a simple piece of kit. If people are happy to pay £30 for this cap, they would not be disappointed with its wind resistance and warmth, but others are available considerably cheaper that perform to a similar standard.
Does the job well, comfortable, simple and windproof; possibly too expensive, but it works.

Tell us some more about the technical aspects of the product?
Vented front panel
Ergonimically designed for ease of neck movement
Very strong stitching throughout the majority of the cap. Possible question marks about the stitching around the base, but aside from this, very well made.
Can't fault it. I was limited to a minimum of 5˚C, but could see this cap still being comfortable at much lower temperatures.
Strong stitching and well chosen materials mean that it would last well. Possible question mark over stitching at the base, but even if this broke completely, it probably would not have an impact on how the cap performs.
Very comfortable, breathable when necessary combined with no undue pressure and easily fits underneath a helmet with nothing pressing into your head.
Can get similar products cheaper, are they are as good? Probably not.
