I bought this one from China. Website is Ali Express. Was rather dubious as wasn't sure of the website or the product itself but thought it was worth a risk at £30. Helmet duly arrived about 3 weeks later and I was really pleased. The helmet was easily as stylish as a £150plus version and also very sturdy: not sure if it officially conforms to British standards but certainly more than matches previous helmets I have bought locally. Also got 3 interchangeable visors with it: the mirrored version is awesome.
