Fluorescent pigment absorbs ultraviolet — invisible to you — and re-emits that energy at a visible wavelength, so the surface returns more visible light than falls on it. That is why it appears to glow in overcast, rain and dusk, when there is plenty of ultraviolet in the sky and almost no contrast on the road. A matt clear coat scatters some of what the pigment emits, so a flat fluorescent finish is marginally less brilliant than a gloss one — the trade is a helmet that reads as a designed object rather than as workwear, and one that hides handling marks. 🔵 Two costs: fluorescent pigment fades under sustained ultraviolet over years, so store it in a garage rather than a window; and matt is washed and never polished, since abrasive compound leaves a permanent shiny patch on a flat coat. If conspicuity is the deciding factor rather than a consideration, compare this directly against the Savage hi-vis at the same price. That one carries fluorescent yellow across more of the shell and in gloss, which is measurably more effective at distance. This is the version for a rider who wants the benefit without the helmet announcing it.\u003c\/p\u003e\n\n\u003ch3\u003eThree visors, one helmet\u003c\/h3\u003e\n\u003cp\u003eAn anti-fog insert works mechanically: it sits slightly proud of the visor with a sealed pocket of air between the two, holding the inner surface above dew point.\u003c\/p\u003e\n\u003cp\u003e🔵 Sprays and coatings need reapplying and fail exactly when humidity is highest.

After any real impact the helmet is finished, whatever the carbon looks like from outside.\u003c\/p\u003e\n\n\u003ch3\u003eThe part you actually touch\u003c\/h3\u003e\n\u003cp\u003e🔵 Washing the lining is the most effective maintenance there is and the one most often skipped. Sweat degrades foam, and the foam is what holds the helmet in position on your head.\u003c\/p\u003e\n\u003cp\u003eCool water, a few times a season, dried away from direct heat.\u003c\/p\u003e\n\n\u003ch3\u003eCarbon or composite — which Vector II to buy\u003c\/h3\u003e\n\u003cp\u003eWhat this helmet is good at: fit, weight, equipment and material.
