Will it fit?
Check your helmet in seconds.
Type your helmet's brand or model. We've checked the most popular helmets sold in Australia and New Zealand against every Da Brim. If yours isn't listed, the fit guide below covers almost everything.
We haven't listed that one yet
That doesn't mean it won't fit. Most helmets do. Check the general rules below, or send us the brand and model and we'll confirm for you.
Not on the list? The rules are simple.
✓ Flush front, removable visor, or a small fixed visor → the cycling brims fit. The compression ring tightens onto the shell, no vents needed.
✓ Any standard horse-riding helmet → the equestrian brims fit (fixed peaks use the pocket method).
✓ Hard hats and modern safety helmets → the PRO range fits.
✓ Treadley hats slip over the top and fit almost any helmet that isn't too big; the Rezzo's band system covers most of the rest.
✕ Motorbike, ski/snowboard and full-face helmets → not compatible.
