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 GripGrab AquaShield Waterproof Cycling Cap does exactly what it says on the label, doing a great job of keeping your head dry in the rain while being almost as breathable as a standard cap. It's pricier than one, though.

The humble cycling cap has a multitude of uses, from protecting your head from the sun, keeping the glare out of your eyes and – to a lesser extent – keeping the rain off. In fact, a standard cap does a very good job.

GripGrab's version is made from a 100% nylon and uses an AquaShield durable water repellent (DWR) coating to keep the water out. GripGrab claims the cap has a waterproof rating of 15K, which I'd say is realistic, as in some thundery downpours it resisted any ingress for at least an hour.

The 15K, by the way, means the fabric has been tested to resist the pressure of a 15,000mm (15 metre) water column before it starts to leak. If my calculations are correct, that's around 21psi of pressure. That's mid-scale in waterproofing terms.

Whether you wear it on its own or under your helmet, water beads off the outer surface. In heavy rain that does mean it can run off and drip down your neck, but the rest of you is likely to be wet anyway.

Hatters gonna hat

Rainwater beads off the peak too, but the peak is large enough that it drips in front of your glasses, so it's no big issue.

Breathability isn't bad considering the coating – GripGrab says its rating is 40K, and I certainly didn't find things get any hotter than I was expecting. Breathability tests are far more varied that waterproofing ones and aren't standardised, however, so that 40K rating is arguably not all that meaningful.

The fabric will soak up a reasonable amount of sweat before it gets overwhelmed, though, so it was only on stormy humid days that I found it too warm to wear. It was a hot and very humid spring period for the test, mind you, and in typical May/June temperatures it would be comfortable. It'll be ideal for use in the autumn too.

It comes in two sizes – S/M and M/L – and its construction is thin and light, so you only need to wind out your helmet's cradle a few millimeters for it to fit underneath.


At £29.95 it's pricey compared to a standard cap, which typically come in at £15-£20.

The GripGrab is cheaper than Showers Pass' Atlas Cap, however – that's a similar design and costs £35. Its Elite Cycling Cap is more roadie than the Atlas, at least, but also costs £35.

Also similar, the Sealskinz's Waterproof All Weather Cap is slightly cheaper at £25.


Most caps do a good job even in the wet, but if you're looking for proper water resistance then I recommend this GripGrab. It offers good weather protection and decent breathability, and the price is in the right ball park too.
