LS2 ADVANT X Carbon review

A carbon-fibre modular helmet: multiple layers of carbon through the shell, multi-density EPS, a reinforced chin strap and a quick-release fastening.

The bottom line The construction is published in detail — carbon throughout, multi-density EPS, a reinforced strap — and the one figure that would prove the point, the weight, is not.

What the seller commits to paper

Multiple layers of carbon fibre through the whole shell, which the maker states distributes impact energy, and a multi-density EPS liner. The chin strap is described as reinforced, with a quick-release fastening.

The figure that is missing, and why it is the important one

A carbon shell is bought for weight. On a modular helmet, where a hinge and a second shell section add mass, it is the strongest argument there is. The listing does not publish a weight — so the argument is made in words and not in a number, and this page reports that rather than supplying an estimate.

Two lines to read on the helmet itself

The approval and its version, and the P or P/J marking that records which chin-bar positions were approved. Neither appears in the listing text; both are on the strap label.

Availability

Between 339 € and 359 € across the German, French, Italian and Spanish Amazon stores, in the single reading behind this page.

Priced in local currency, which the euro range above deliberately leaves out, it also appears on the British Amazon store.

Nothing whatever came back from the American Amazon store, so the buy button there opens a search instead of an empty page.

The declared figures, and the blanks beside them

Strengths

  • Quick-release closure, operable with gloves

Compromises

  • No published weight — which is the entire argument for a carbon shell
  • Neither the approval nor the P/J marking appears in the listing text

What riders ask about this one

Why does carbon matter on a modular helmet?

A modular carries a hinge, a second shell section and reinforcement around the pivot, all of which add mass. A lighter shell material offsets that, and the maker states the carbon runs through the whole shell rather than sitting on the surface.

Where is the approval printed?

On the label sewn to the retention strap, with its version and the country that granted it. The listing text does not repeat it.

Who this one is for

A rider who wants the lightest modular construction available and will weigh the helmet rather than read its weight.
