Treadley hat fits the bill

Another very useful addition to the arsenal against the Qld sun and of course magpies

one slight problem. Even though I got the L-XL size, it on just got over my helmet, which was not that big a helmet.

Treadle Explorer Helmet Hat

The hat is fantastic for my husbands helmet, my only problem is my helmet size. My husband has a smaller helmet than I have & his hat fits the helmet perfectly but my helmet is larger & the hat’s elastic is not big enough to get around the back of the helmet. I am hoping the wind under the brim will not drag the hat off the helmet as I ride along. One size does definitely not fit all helmets. You could do with a large size for larger helmets.
