Bontrager Lithos Helmet Review

At A Glance

The Lithos from Bontrager is a new helmet for them this year, aimed firmly at the trail riders and all mountain enthusiasts it adds to their already impressive collection of XC and road orientated lids. It features an In-Mold composite skeleton, which enabled the team to put plenty of vents into the lid without losing strength. The adjustment for fit is controlled by the “Micro-Manager” which is a twist wheel system at the back of the helmet.

Inside you’ll find AgION fit pads, which wick moisture and are antimicrobial to keep odor at bay. There are also recessed channels on the inside of the helmet to promote ventilation and increase airflow as you ride. The visor is removable and fully adjustable too.

On the Trail

Slipping the Lithos onto your head it is easy to get a solid fit with the Micro Manager adjustment system. The Slim pads and large vents promote lots of airflows and even in the humidity of North Carolina, the helmet performed really well. The helmet has quite a low profile and doesn’t have that “mushroom” look which will appeal to plenty of riders. With generous coverage around the back of the head, it does well in the safety and style stakes. With 18 vents it is certainly one of the coolest all-mountain styled lids around. It is priced reasonably too, so if you want great protection, style and something that won’t break the wallet the Lithos is it. Available in three sizes; S: 52-56cm, M: 54-60cm, l: 58-64cm, with a multitude of colors, you should be able to find one that fits the bill.


Stylish, well-ventilated and great value, the Lithos packs a bunch of tech into a very neat package. We loved the adjustable visor, the great venting and the coverage around the back of the head.
