While some of the helmets that are in the market will be able to offer you adequate protection, wearing them for a prolonged time can be a bit unformattable. Well, Troy fixed that with the A1.

To begin with, it comes with eight pressurized intakes on the front. These intakes will let the cool air pass through the helmet, which will ensure that the inside does not get uncomfortably hot.

Apart from that, there are eight vacuum vortex outlets. They are located at the rear of the helmet.

These outlets will ensure that the cool air that the intakes are letting in gets dispersed to the internals efficiently. That means it will draw the heat out of the head area.

The manufacturer did not take the comfort factor lightly. Apart from all the vents, they also included an ultra-plus, single-piece liner.

The liner is of anti-microbial wicking material. It will suck up all the moisture from the inside and keep your head dry. You will be able to remove it and wash it when it gets too dirty.

Other than just keeping your head cool, it did not skimp one bit in the overall protection.

It comes with a shell that is in-mold polycarbonate. The shell is accompanied by impact foam that is of EPS.

These will be able to ensure that you do not get seriously injured if any accidents do happen on the road.

Lastly, the race-inspired design that it features — makes it look sleek and modern.


  • Features eight intakes on the front for cool air
  • Eight rear vents for pushing warm air out
  • Comes with a moisture-wicking liner
  • Liner is removable and washable
