MET Kaos UL helmet

Our review

Impressively light, yes, but super expensive in comparison to the best of the rest

The Kaos UL is claimed to save 50g over the standard (and £15 cheaper) Kaos, only our sample doesn’t: the standard large Kaos we compared it to weighed a scant 15g more.


The extra £15 buys you Kevlar straps, a gel forehead pad to reduce the chance of sweat dripping into your eyes, and MET’s Ultamalite construction.

Head coverage is generous, as you’d expect from a helmet aimed at more aggressive riders, and the full-circumference cradle is easy to adjust, providing good, solid support. The in-moulded shell extends around the base at the rear, and the weight is undeniably low for its class.

If you want a light trail-styled lid then there’s nothing wrong with the UL, however it’s increased in price by £25 since we last tested it and


is now 45% more expensive than the similar quality Bell Sequence and Specialized Vice, so you’re paying a premium for the light weight.
