Good Winter Biking Helmut

In expensive, decent quality winter biking helmet with ear protectors. Reduced air vents at the front reduces the cold factor. Good fit, seems hefty. Would be nice with more colour selection.

Thanks for the review Simon!

Helmet keeps the ears warm

I purchased this helmet as it had the ear muffs to cover your ears, I was riding my bike well into the fall last year and I get earaches very easily. Having the covers over my ears made it very east to ride in the morning to play Pickleball.

Great helmet

I’d looked around at lots of other more expensive helmets but this model fits really well, has removable ear covers and visor and and the ability to attach an additional light plus …. It looks tremendous!.. especially with the Sun glasses.

Very noisy helmet

I actually bought this with the hope to have less wind noise with an ebike (ears protected but still able to hear what’s going on) this makes it worse with a bad wind noise which is actually covering most of the traffic noise at speed (25kmh) Will probably return it

Great helmet

Great helmet, the ear defenders work well. They keep out the cold and the wind but don't restrict road noise so you can still hear perfectly.

A revelation

I've been riding with a regular bike helmet for ages and it's always felt like it's perched on top of my head. Plus, I get earache if it's cold, and if I wore a hat and helmet I would overheat. To have ear protectors and a fuller helmet in one package seems a no-brainer, but the market's not crowded with options. So, good fit, even on my huge noggin (I got the biggest size) and no earache, and the price is good too. I'm happy

Excellent delivery price and quality

Came in Useful Sooner Than Expected

The helmet is very comfortable and easy to adjust. Second day out on my new bike and I fell of it twice, no damage to head so the helmet did it’s job

This is the second helmet of this type I have bought. Originally purchased for our eldest son and the second one is for our youngest. Sizing is great and really easy to alter using the rear spin adjustment wheel, a lot better than trying to get the fit with lots of Velcro pads! Quality: really well made! Extras: you can fit a light on the back too! Great for scooter/ bike safety! Ear flaps ( removable/ washable) are a nice touch to keep the chill out, without hindering hearing. No cons! Well worth the money and should last ages ( if looked after). I’d happily have one myself.....

En 1078-certified

Complies with the cycling helmet standard EN1078 (2012) + A1(2013). European standard defining the test requirements and methods applicable to helmets used for skull protection when cycling around town and for skating, scootering and skateboarding. The corresponding test requirements and methods cover the following aspects: construction, including field of vision; shock absorption properties; retention system characteristics.


If you're between sizes, choose the bigger size.Choosing the right-sized helmet and getting the fit right is essential. For children, never buy a helmet that is too big on the assumption that they will grow.M: 21.7” - 23.2”L: 23.2” - 24.4”


For maximum protection, the helmet should be in close contact with your head, and the fastening system must always be correctly adjusted without being too tight around your forehead. When the straps are properly adjusted, the helmet should not slide forward, back or sideways. For this reason, there are several sizes available. We recommend that you try on different sizes to find the best fit.
