I like that it is very high. Quality I would say 1a !!
The size I have measured themselves with me on the head and the cap is comfortable to wear.
not too tight, that there is a headache and not too far that I lose.
So here: order the right size! No bigger! Not less!
I especially like the "food". Eben that directly lies on the end but no plastic material, then it is at the end not so sweaty, even while wearing the Elbsegler longer.
