Currently our Kickstart helmet comes in one size only -- and it should fit most heads from 54-61cm, and up to 62cm. (Approx. 21.3 - 24 inches, up to 24.4 in.)
If your shipping country is the contiguous USA, Kickstart is available in size XL as well. XL is suitable for heads from 60-64cm (approx. 23.6 - 25.2 inch) and currently only available as standard version, which means it does not have the option to add MIPS.
Please note that if you add MIPS to your helmet, it will lower the available circumference by maximum 1 cm.
It's a simple task to measure your head size. You can check out the video below:
If you have a relatively wider head, we suggest you to try it at a store before you buy it if possible.
If you purchase from our website (lumoshelmet.co) we have a returns policy where you can get a full refund within 30 days. Just keep your packaging and note that you'll have to pay for return shipping.
