SIDI’s New Fulmen and Gravix Goggles: Lenses, Prices and Spare Parts

SIDI, the Italian company most riders know for its boots, now sells motocross goggles. Its web store has a new goggles section with three models: the Fulmen Mirror, the Gravix and the Gravix Smoke, plus a separate page of replacement lenses and roll-off parts.

SIDI's goggles collection describes the line as built for motocross and enduro. The product pages carry a "New" label but no launch date. Trade coverage of the line appeared on Oct. 14, 2026.

Key points:

• Three models: Fulmen Mirror at the top, then Gravix (clear lens) and Gravix Smoke (tinted lens).
• U.S. web-store prices: $114, $68 and $80 when we checked on Oct. 14. The European store lists €99, €59 and €69.
• Lenses: only the Fulmen comes with two, a mirrored lens for sun and a clear one for low light.
• No safety standard named: SIDI's pages don't say which eyewear standard, if any, the goggles are tested to.

The three models, side by side

These are the three goggles as SIDI lists them.

1. Fulmen Mirror ($114 U.S. store): a mirrored Category 2 lens plus a clear Category 0 lens in the box, triple-layer foam, a jacquard elastic strap, adjustable outriggers and what SIDI calls its FLOW CORE vent system. SIDI gives the weight as 135 g, a little under 5 ounces. Seven colorways.
2. Gravix ($68 U.S. store): one clear Category 0 lens, dual-layer foam, a silicone-lined elastic strap and adjustable outriggers. Seven colorways.
3. Gravix Smoke ($80 U.S. store): the same Gravix frame and strap with a smoke-tinted Category 1 lens instead of the clear one. Seven colorways.

All three are one size. SIDI says each has an "anti-intrusion" frame meant to keep debris out, an anti-scratch lens treatment and an anti-fog coating, and that the foam and other parts can be replaced as they wear.

The Gravix pages don't list a weight or the FLOW CORE vents, so don't assume those carry over from the Fulmen.

Picking a lens tint

Goggle lenses are graded by how much light they let through, called visible light transmission (VLT). SIDI publishes these ranges for its lens categories:

• Clear (Category 0): lets through 80–100% of light. For cloudy days, woods riding, and dawn or dusk.
• Smoke (Category 1): 43–79%. For mixed sun and cloud.
• Mirror (Category 2): 19–42%. For bright, open tracks.

If you ride in changing light, the Fulmen is the easiest pick, because you get the clear and the mirrored lens together. With a Gravix, you'd buy the second lens separately.

One oddity: the Gravix and Gravix Smoke pages also include a line reading "range lenses use: S2 mirror," which seems to be copied from the Fulmen page. Neither Gravix lists a mirrored lens in the box.

Spare lenses and roll-offs

SIDI has a separate spare-parts page for the goggles. When we checked, it had 13 listings, all priced in euros and all marked "available soon":

• Replacement lenses: clear S0 (€15), smoke S1 (€19) and mirrored S2 in gold, pink, red or silver (€35 each)
• Roll-off system: a 50 mm roll-off kit (€75), plus the mechanism (€50), a roll-off lens (€25) and a six-pack of film (€35) sold on their own
• Tear-offs: a 10-piece pack (€17)

Roll-offs and tear-offs matter in mud. A roll-off pulls a strip of clear film across the lens as it gets dirty. Tear-offs are thin layers you rip off one at a time.

The clear and smoke lenses also come in OTG versions, a label usually used for goggles made to fit over prescription glasses. SIDI's parts page doesn't say which frame each part fits, so check before you order.

Buying them in the U.S.

SIDI's site has a United States storefront that shows prices in dollars, and it links to a U.S. store locator and a page of SIDI distributors in the USA. So you may be able to find these at a dealer instead of ordering direct.

A few things weren't clear when we checked:

• Stock: the U.S. collection page showed most colors in stock, with two Fulmen colorways (white-pink and white-silver) marked "available soon." The individual product pages showed every color as unavailable. Your cart is the real test.
• Shipping: the product pages only mention free shipping on EU orders over €99. U.S. shipping is "calculated at checkout."
• Price basis: the U.S. prices are labeled "tax included," which is unusual for a U.S. listing. Confirm the total at checkout.
• Warranty: SIDI lists a two-year direct warranty. The pages don't say whether that's handled any differently for U.S. buyers.

What SIDI doesn't say about protection

SIDI's Fulmen page calls its S2 lens "certified" but doesn't name a standard, and none of the three pages lists one. The impact-resistance and anti-fog claims are SIDI's own. We haven't seen independent test results.

If your race series or club has an eyewear rule, or you just want to know what the lens has been tested against, ask the dealer or SIDI for the paperwork. SIDI's customer-service menu includes a "Conformity Docs" link for its products.

What we still don't know

• Launch date: SIDI hasn't put a date on the new line.
• U.S. pricing for spare parts: we only saw euro prices.
• Compatibility: which lenses, roll-offs and tear-offs fit the Fulmen versus the Gravix.
• Testing: any named standard or independent test for the lenses and frames.
