Arai Viper GT

The comfort and fit of the Viper GT, and the ability to alter the internal padding to fine tune the high level of comfort further makes this a great investment, you can pretty much put it on and forget you're wearing it, it's that comfortable, no pressure points, or uncomfortable areas. The helmet has a number of vents, 2 in the visor which help to keep the visor clear, but a combination of the breath guard and fitting the supplied fog city insert to the visor (no drilling required - it' already compatible) means that I've not yet had the visor mist up, even when at a standstill in the cold/rain. The extra visors, in the chin, and a further 4 on the top of the helmet make this great for a hot day, no more taking off the helmet to find a soaking inside - and if you did get it wet/dirty the whole liner is removable. Visor release - though advertised as quick release does take some getting used to, and I ended up watching a couple of clips on Youtube to get the hang of swapping visors - don't be alarmed by the loud 'clicks' when you remove & insert the visors! At speed this helmet is one of the quietest I've experienced, and with the clever flap under your chin which allows you to extend a small mechanical flap to close the gap between the lower edge of the front of the helmet and your chin/upper neck.

The only downside is Arai's cost - but this helmet has had Arai's R&D ensuring it does it's job well, it's designed to protect your head - spend whatever you can afford to protect it!
