Our Kickstart helmet should fit most heads from 54-61 cm, and up to 62 cm. (Approx. 21.3 - 24 inches, up to 24.4 in.). Kickstart in size XL is exclusively available for shipping to the contiguous USA. XL is suitable for heads from 60-64cm (approx. 23.6 - 25.2 inch) and is currently available as the standard (non-MIPS) version in Charcoal Black, Pearl White and Electric Lime.
The size of the Matrix and Street helmet is 56 – 61 cm (approx. 22 - 24 inches).
Please note that if you add MIPS to your Kickstart, Matrix or Street helmet, it will lower the available circumference by maximum 1 cm.
Our new Ultra helmet comes in S, M-L and XL, though the availability depends on your shipping location and can be checked on our website. Ultra sizes:
Size S: 51 - 55 cm (20 - 21.6 inch)
Size M-L: 54 - 61 cm (21.3 - 24 inch)
Size XL: 61 - 65 cm (24 - 25.6 inch)
Adding MIPS to your Ultra helmet does not impact the size.
Do you have helmets for kids?
At the moment we do not have helmets for children. If you would be interested in this, please fill out survey here.
Many parents backed Ultra in the Kickstarter campaign and got it in size S for their kids, so we know it may be a good fit for the youth! Ultra in size S comes only with MIPS and is not available in standard form (non-MIPS).
I need another size
We are constantly updating our products and we may offer different sizes in the future. If you are looking for a different size, you can help us by leaving your head size here, so we can take it into consideration when releasing new products.
