Helmet Sizing

Measure around your head at the widest point to determine the size you need.

    "A Great fit and a great look, this reminds us of superb helmets that come in twice the retail price" - "As soon as we saw this lid, we were smitten. It looks good, feels good and at 80 quid it oozes value" - BikesEtc Magazine Gold Award - Best on Test 10/10

    Built using an advanced three-part shell construction the Notus majors on protection, not just great looks. A full coverage EPS core is co-moulded over the internal fittings that anchor the straps and occipital cradle into the body of the helmet for maximum durability.

    With 60mm of size adjustment for each model, Antibacterial treated comfort pads and a wrap-round chin strap protector the Notus is built for comfort. Try one for size.

    A correctly adjusted chinstrap is an integral part of the safety provided by any cycling helmet. If your chin strap isn’t correctly tensioned there is a risk that the strap may pull through the buckle. Always make sure that the chin strap is adequately cinched up every time you put your helmet on. A loose chin strap potentially reduces the effectiveness of your helmet.
