Protos integral arborist helmet - size

[Akra]

Looking at buying one of the Protos integrals.
But I have a tiny head.

I'm not able to get to a store to try one on so looking for anyone else with a tiny head who owns one to give me their experience.
My head size: 54cm - not diameter! ha ha. The helmet is stated as being 54 - 63cm. So right on the borderline.

Lol love how you are owning your tiny head.

You can probably help beef up your noggin by putting a buff on folded onto itself (double layered). It doesn’t seem like it would, but just a single layer of buff makes a big difference for me in a helmet adjustment.
