And also, I kind of bought my Masuri without really considering other options. I've got quite a 'long' head so I had to go for the Large size. At first I couldn't believe a lid (the first one I ever bought) costing such money and so highly regarded could be so uncomfortable. The sidways movement was crazy and It seriously felt like I was missing some padding on the inside or I had a duff helmet. Thankfully/Luckily I also have longish hair that needs to be held back, so stuck a sweat band on and then I was in helmet nirvana! It fitted, and held on, like a dream. So much so I couldn't tell you much difference now between a baseball cap and the Mas.
I suppose I'm in good company here to admit (for shame!) I initially took the Masuri on looks and reputation/heritage (and don't get me wrong, I'll never go back now), though frankly as a technical exercise (and if you don't mind your cricket gear looking as if it was made in the last 20 years, which I try not to!) then the Ayrtek's are a different league to the others. It's very impressive how a tiny player (in the business sense!) in the game has gone through the whole R&D process and manufactured a truly game changing (in the business sense!) piece of equipment, and should be massively congratulated IMO (obsequiousness over!).
Oh, and in response to your original point, you're right, the chin strap is crazy short. As the top part is wedged tightly around my 'dome', the bottom bit fits snugly between my chin and my neck, , merely to keep it flying back off.
