Zero RH+ ZY Helmet



Very comfortable helmet with good venting and easy adjustment

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.

What the scores mean

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

The Zero RH+ ZY is a very comfortable helmet with good venting and easy adjustment. I reckon it's pretty cool-looking too.

The ZY is Zero RH+'s third tier road helmet after the ZR and the ZX although it has a high-end look and feel to it - and by most people's standards a high end price tag too. We've reviewed the ZX before on /content/review/81500-zero-rh-zx-helmet and also reviewed the ZW /content/review/78263-zero-rh-zw-helmet, and we liked them both very much.

The same is true of the ZY. Although it's fairly low profile, it's a deep helmet so you get the feeling that your head is fully encompassed – properly inside it – rather than that you have a lid slapped on top.

Fit is well handled by Zero RH+'s Power Fit Double System. You get the choice of three height positions for the back of the cradle and you adjust tightness via a clickety-click wheel at the back. It's a big, chunky wheel and you can't miss it for adjustments even if you're riding in padded winter gloves. I set the cradle so that it would sit as low as possible on the back of my head and it felt about as secure as any helmet I've ever tried.

There are plenty of big vents that grab generous scoops of air and usher them inside and then the helmet channels air over the top of your head effectively. At least, I stayed cool enough even on some super-hot rides while wearing the ZY. Most manufacturers have got airflow pretty well sussed these days and it's rare that we get a helmet that's uncomfortably hot, but I'd say this one is particularly good when it comes to ventilation.

The padding inside – RH+ Zero call it Stratosoft padding – is really comfortable and one long pad right across the forehead stops sweat from funnelling down into your eyes. Well, that's unless you get the padding absolutely soaking, but that's likely to be rare.

Unusually, Zero RH+ add a pad just inside of the tightening mechanism at the back. This reduces the pressure back there much more than I expected it to; it's a really useful addition. You can easily remove all of that Stratosoft padding for washing.

The ZY is inmoulded – so the EPS (expanded polystyrene) structure is fused to the thermoformed polycarbonate outer shell – and there's an inner frame within the EPS to stop the helmet breaking into pieces in the event of an impact. We don't crash test helmets, but the ZY conforms to EN 1078, of course. All helmets have to.

The inner frame allows RH+ Zero to use those large vents and keeps the weight down to 245g (we have a XS-M, 54-58cm sized model; the L-XL will be a little heavier, obviously). That's not mega-light but it's a reasonable weight. Unless you're very sensitive to this kind of thing, you'll hardly feel you're wearing it.

The ZY comes with a soft microfibre strap cover to avoid any neck irritation – just take it off if you don't want it – a couple of reflective panels around the back that look white in daylight, and its own little bag to avoid scratches, which is a nice little touch.

If this red/white version isn't for you, several other options are available.
