When Mtbr goes to product launch media events where the journalists can wear the helmet of their choice, we typically see more Troy Lee Designs A1 helmets in use than any other model. That's high praise that can be attributed to the comfort offered by the A1, as well as its attractive designs and colors.

New for 2016, are even more impressive colors, especially in the Vertigo series, which shares a similar design structure but different colorways.

More importantly, Troy Lee has upped the protection by incorporating MIPS into the A1 series. MIPS adds 23 grams resulting in a 400 gram weight for M/L size. Price rises $50, so the top-of-line Vertigo helmets are $215, and the Drone designs are $189

Ride impressions

We've taken the A1 MIPS helmets out for a few rides already and have a few initial impressions. First, the weight is about the same as the 23 extra grams is not noticeable compared to the normal version. Second, it is a MIPS helmet so there is some millimeters of sliding sensation if you wiggle the helmet around your head once strapped in. It's not as firm a feel as a non-MIPS helmet but it doesn't move around while riding.

There is less padding on the helmet compared to the non-MIPS version and one of our riders with a bald head has noticed the lack of it. He longs for more of the TLD lining which is one of the best in the category.

Ventilation seems slightly affected as the MIPS layer is in the way of airflow. The MIPS material has been strategically cut out to match the vent holes but from the forward facing angles, you can see there is the slightest bit of obstruction. We'll keep an eye on this as we use the helmet more during the hotter summer months.

Overall, we're happy that one of our favorite helmets still has category leading designs and that it gives our brain more protection against soft blows and rotational forces.
