Bogotto SH-800 Spaceman 頭盔

I bought this as a second helmet as the price was so good and I wanted I try the Bogotto brand. The helmet is fine, fits well and is eye catchingly different but it is let down by the visor. Almost as soon as you stop the visir will fog up, so you need to vent it and here it the problem, I find it impossible to do with one hand, especially in gloves. The hinges are very stiff but the worst point is there is only a single lift point, on the left side, which is too far to the rear. This means when applying pressure to lift the visor you're only lifting the left side/edge which does not break the seal from the front or right side. It should be in the front centre as on my other helmet. It's a disappointment as the helmet as a whole is cool and great value at a discounted price.
