3XL helmet, where to find?

Hi!

a recurrent member of my crew will need a 3XL helmet. So far, we only were able to find a motorcycle one, on the A... site, too heavy, will have to return it, on a sailboat you're on your side a lot.
HouseOfScuba got us to Murray's, unclear if they actually have one, awaiting their response. Maybe someone knows some oter resource?

Since apparently sizes are inconsistent (8 1/4, 65) , actual measurements are 25 inches / 164 cm

We would buy it new or used.

Any advice, opinion, appreciated.

maybe a bicycling or climbing helmet? An old Petzl Ecrin Roc would be good since it has a hard hat type suspension so there is nothing to would be damaged or uncomfortable it it gets wet.

That's the idea, any port in a storm

We're still looking. Maybe most bicycling / climbing stores either don't carry those, or their offers are not displayed by our data search masters... I could make my own, but there are excellent reasons not to.

I found this. You could google the various helmets listed. I saw the Petzl Ecrin Roc isn't big enough, that's a shame.

Wow, it is hard to find bigger helmets. Not cheap, but this looks good.

Yup, it was surprisingly hard. Thank you for that list! Seems to be the one resource. For updated info, look at their Helmets of the Year page, and search by XXL and such. https://helmets.org/helmet23.htm

I bounced from there to Reddit, and found a positive comment for the Specialized Align II XL. Turns out it's available, on sale, $33 on ebay. So I'm getting it, and returning the very nice, but too heavy and quite more expensive $150 Bell motorcycle one, which was the only one large enough that we were able to find before. I find it outrageously interesting that our search engines are not able to get us easily to this kind of resources (or didn't get me, )

For future reference....Protec make great helmets for water sports. I use the Ace Water model for rafting and sailing. They make a XXL size.
