This is my first Shark helmet, so I wasn't sure what to expect, though I know one road racer who has worn them for years, so I knew they weren't rubbish.
When I first tried it on, I thought I had ordered the wrong size, it felt very tight, but once I got the chin curtain over my chin, the helmet somehow fitted me perfectly though it still seemed a bit tight, until I realised that's how a helmet is supposed to fit, my 4 year old helmet lining had relaxed that much, it was actually loose.
Great visor, nice free pinlock and lining is seriously plush.
Lovely helmet, highly recommended!
