S1 Helmets

We have the largest collection of S*One Helmets in stock in Aotearoa. If it is listed here, it is in stock and ready to ship. If there is a specific style you don't see, please contact us and we will be happy to order it for you. 

The S*One helmet comes in three distinct shell sizes:
- Mini Lifer for Kids (46.9cm to 52.1cm)
- Lifer  (52.1cm to 59.4 cm)
- Mega Lifer for larger heads (58.4cm to 64.7cm)

Helmets are sized to fit within those three shells via adjustable and replaceable pads. It is our experience that about 90% of folks over 13 years of age fit into a Lifer, but please use the size chart and measuring technique below for correct sizing. As there is some overlap between the size ranges, if you are between shell sizes, opt for the larger shell size.
