Could I find a skating helmet larger than 60 cm?

I just took up inline skating and bought an XL pro-tec helmet that says 59-60 cm, but it squeezes the sides of my head so tight it gives me a headache and I'm worried about circulation. This is a hard thick one that goes around to the back of the head; I tried on the lighter kind that just covers the scalp and it didn't hurt as much, but even after adjusting it all the way, I couldn't get the strap near my chin and it was too small to the point of almost choking me. I asked the guy at the store if that's as big as they come and he said yes, but I still hope there's a way I can enjoy this hobby safely and comfortably.
