{"product_id":"ls2-ff811-vector-ii-solid-concrete-helmet","title":"LS2 FF811 Vector II Helmet – Solid Concrete Matt","description":"\u003cp\u003eConcrete is a warmer, denser grey than Nardo and it comes in matt rather than gloss — the version for a rider who wants a grey helmet that reads as a material rather than as a colour.\u003c\/p\u003e\n\n\u003ch3\u003eA four-star shell in six sizes\u003c\/h3\u003e\n\u003cp\u003eMost full-face helmets in this class use one, two or three shells.

That is a description, not a verdict.\u003c\/p\u003e\n\n\u003ch3\u003eAbout the solid concrete matt finish\u003c\/h3\u003e\n\u003cp\u003eThe name is doing real work here. Where Nardo grey is a cool, slightly blue industrial tone, Concrete sits warmer and heavier, and under a flat finish it reads much more like a cast surface than a painted one. On a compact shell like the Vector II's that suits the shape: there are no reflections travelling along the curves, so what you see is the geometry of a helmet that six shell sizes have made properly proportioned. Practically it combines the two properties that matter most over years. A mid grey hides road film better than any other value, and a matt finish has no clear coat for handling marks to catch in — and this is a helmet that gets picked up and set down constantly, because it is compact enough to be carried by the aperture. 🔵 Matt has one absolute rule: wash it, never polish it. Abrasive compound cuts a permanently glossy patch into a flat coat and nothing will blend it back out. If you are choosing between the two greys at 220 €, both hide road film equally well. Nardo is the cooler tone in gloss and shows the shell's curvature; Concrete is warmer, matt, and forgives careless cleaning entirely. Neither will need any real attention across five years of use.\u003c\/p\u003e\n\n\u003ch3\u003eTwo visors in the box, a third inside the shell\u003c\/h3\u003e\n\u003cp\u003e🟢 \u003cstrong\u003eTwo visors in the box, a third inside the shell.\u003c\/strong\u003e The clear one is fitted, the tinted one is supplied complete, and the drop-down shield lives between the shell and the liner.\u003c\/p\u003e\n\u003cp\u003e🔵 Certimoov praised the field of vision and criticised the shield's mechanism.

If you can roll the helmet forward off your head with the strap fastened, it is loose or the wrong size.\u003c\/p\u003e\n\u003cp\u003e🔵 A ratchet holds at a preset length and that length drifts as the padding beds in — re-check it after the first rides and each season after.\u003c\/p\u003e\n\n\u003ch3\u003eThe part you actually touch\u003c\/h3\u003e\n\u003cp\u003e🟢 \u003cstrong\u003ePre-moulded intercom pockets\u003c\/strong\u003e are worth more than they sound.
