Dark Shadow Mat carries the same restrained, undecorated shell as its glossy sibling, in a flat matte black instead — a version built for riders who want the OXO's flip-back trick without any finish that draws a second look. Undo the two catches at the chin, and the whole lower half of the helmet swings back and locks against the crown; the same shell that was closed and homologated for full-face riding a moment earlier is now an open helmet, not a different one pretending to be.

The finish, beyond the photo

The matte coat here is a true satin lacquer rather than a rubberised soft-touch layer, so it cleans with a damp cloth instead of collecting grime in a textured surface. It's a finish that ages more gracefully under fine scratching than gloss black, though a deep scuff will still show as a lighter mark rather than disappearing the way it might on a busier decor. Paired with the black interior trim and the small red release tabs at the chin, it's the quietest-looking way into the Dark Shadow name.

The mechanism behind the name

Flip-Up describes a category of helmet, and the OXO earns the name literally: the chin bar hinges at the sides and rotates fully back over the crown when you release its two catches, rather than lifting away or unclipping. It's a single, continuous shell in both positions — full-face when locked down, open-face when rotated back — which is a different engineering problem from a jet helmet that was never designed to carry a chin bar at all, and a different certification problem too.

Closed and open, both certified

Riding a flip-up with the chin bar locked back is only as legal as its homologation allows — some designs are approved closed only, some for both. Shark states the OXO carries dual, P/J approval, tested and certified in both configurations. The underlying standard, ECE 22.06, is the current EU requirement since 2024, testing eighteen impact points at multiple speeds, adding an oblique-impact test against an abrasive anvil, and scoring rotational energy through a Brain Injury Criterion that the older 22.05 standard skipped.

Two shells, and a visor family that knows it

The VZ390 visor family exists specifically for the OXO, and it's built around the fact that the shell itself comes in two sizes. Shark's documentation is explicit: two visor sizes, one per shell size, for every tint in the range. It's a small piece of engineering discipline that a single-shell helmet doesn't need to bother with, and one worth knowing before ordering a replacement visor by tint alone.

1,660 g on paper, more on the scale

Shark's stated weight for the OXO, 1,660 g, is a first-shell figure — the lightest version of the helmet, not the number every buyer will actually carry. SHARP's own independent test weighed roughly 1.7 kg; MotorcycleNews weighed their unit at 1,880 g, over 200 g above Shark's figure. Over a long ride that gap sits entirely on your neck, which is why it's worth reading a manufacturer's weight as a floor rather than an average.

Price in context, not in isolation

This OXO's price only tells half the story alone — set against its nearest real neighbours in Shark's own 2027 line-up, the picture gets clearer:

Airflow and acoustics, both configurations

Two intake vents are confirmed on the OXO, chin and brow, each simply open or closed with no in-between position; the exhaust side isn't documented by Shark, so it stays unstated rather than invented. Noise-wise, independent testing in open, jet mode through town reported no issues, and a separate reviewer's general expectation is that the OXO runs quiet — tempered by the same reviewer's note that earlier Shark flip-ups could get loud at motorway pace. No dB reading is published for this helmet.

Vision, factory-fitted and beyond

Clear, all-user approved, Pinlock 70 pre-fitted, adjustable central lock, anti-scratch coating: that's the standard VZ390 visor on every OXO. Shark's parts range extends it with a TE50 light tint for daytime road use, and five racing-only Iridium tints — blue, gold, silver, red, rainbow — that aren't cleared for the public road. One thing the VZ390 family doesn't carry, unlike another Shark visor shared across several models, is a stated optical class.

Daily use, feature by feature

Confirmed on the OXO: an internal drop-down sun visor, shell space built for an intercom, a visor that comes off without tools, and a glasses-friendly groove in the liner. What isn't confirmed anywhere reviewed is whether the removable interior is also washable, or what pad-size options exist — so both stay unclaimed rather than assumed favourably. SHARP tested the helmet in May 2025 and rated it four stars.

Who this decor suits

Filed the same way as the gloss Dark Shadow — Touring and Street — because the matte finish doesn't change what this helmet is built to do: open at the chin bar for a fuel stop or a slow crawl through traffic, then close back up for the next motorway stretch. It's a helmet for riders whose week mixes distances and speeds, not one built around a single fast lap.

Fit across a two-shell range

Six sizes split over two shells means the OXO's internal shape isn't obligated to feel consistent end to end, unlike a helmet built on a single mould. An independent review describes the fit as more oval than round, and notes it didn't suit that particular reviewer's own head — worth reading as one data point rather than a verdict, but a genuine one, and a reason to try before you commit if your local dealer stocks it.

Buying the right visor, not just the right colour

The OXO's official spare-visor range runs to sixteen options — clear, TE50 light tint, and five Iridium colours — priced roughly EUR 31 to EUR 85, with every single one issued as a small-shell and large-shell pair. The Pinlock 70 insert follows suit, with two distinct part numbers confirmed independently in the range book's cross-reference table. Shell size is not optional information when ordering.

Where the OXO falls short of a perfect scorecard

MIPS and EQRS are both absent from this helmet's safety feature list. No independent source has measured its noise level in either configuration. SHARP's four stars come from one test, in May 2025 — a solid result, not an open-ended promise. The exhaust side of its ventilation isn't published anywhere reviewed. And one tester's independent account found the fit too oval for their own head. All five points are worth reading before, not after, buying.

Five years, and a helmet that's ready to ride

The OXO's warranty runs five years, with spare parts genuinely available afterwards rather than a promise that quietly lapses. It arrives with the clear VZ390 visor already fitted, Pinlock 70 included, and the internal sun visor built in from day one.
