Segmented aramid shell
Overlapping ballistic panels spread impact energy across the structure instead of concentrating it at a single point of contact.
Devtac Ronin · NIJ Level IIIA
A tactical advantage, beyond the status quo.
The Ronin is a full-face ballistic helmet built around a single idea: that head protection should not force a choice between coverage, weight and field of view. Designed, tooled and assembled in Japan since 2011.

The Helmet
Full-face coverage, without the penalty.
Most full-face protection buys its coverage with weight and a compromised field of view. The Ronin distributes mass across a segmented aramid shell so load sits on the structure rather than the neck, and keeps the sight lines a shooter actually needs.
| Protection level | NIJ 0106.01 Level IIIA |
|---|---|
| Shell material | Ballistic aramid composite |
| Shell frame weight | ≈ 1.0 kg |
| Complete helmet | 2.2 – 2.7 kg by configuration |
| Sizes | Regular / Large, each Short or Long |
| Included mounting | NVG shroud · 20 mm side rails |
Engineering
Full technical detail
Built as a system, not a shell.
Every Ronin is an assembly of independently replaceable components. Damage a face plate and you replace a face plate, not the helmet.
02
Balanced load path
Mass is carried by the back helmet panel and the inner suspension frame, moving the centre of gravity closer to the wearer's own axis.
03
Modular by design
Cheek plates, mandible, lenses, crown panel and ventilation are all separate parts. Swap, upgrade or omit them per role.
Why people buy one
How it is built
Ten questions you already know the answer to.
Every one of these is a problem someone met wearing something else. The Ronin exists because of them.
-
Ever worn glasses on a humid day?
A micro jet fan sits inside each lens frame and moves air across the lens. The Flextech eye foam seals the rest out.
-
Ever worn a helmet in 40 °C heat?
Twin crown fans pull the hot air out through the ducted top panel. Two hours of running on one 9 V battery.
-
Ever tried to cheek weld on a full glass visor?
The magnetic cheek plate is detachable. With it removed, your cheek rests directly on the rifle stock and you can aim.
-
Ever put a counterweight on your helmet?
You do not need one here. The back panel and the inner suspension frame carry the mass, so the centre of gravity sits near your own axis, and the load spreads through the frame instead of pressing down on the crown the way a traditional ballistic helmet does.
-
Ever been shown a back-face deformation figure?
.44 Magnum SJHP at 1,430 ft/s: 11.39 mm. .357 SIG FMJ FN at 1,470 ft/s: 8.9 mm. Level IIIA, and it covers the face.
-
Ever had to buy a whole new helmet?
Every panel, frame and plate is its own part with its own price. Damage one and you replace one.
-
Ever replaced eyewear over a single scratch?
The lenses are ANSI Z87.1 and come out in seconds, in clear, smoked, high contrast yellow, high contrast red or marine blue.
-
Ever tried to get a full helmet off an injured person?
It opens in half. The back helmet comes away and the front runs on the six-point buckle set as a mask.
-
Ever mounted night vision on a full-face helmet?
The NVG shroud is part of the crown panel rather than a bracket stacked on top of it, so the optics sit low and on the helmet's own line.
-
Ever looked this good doing any of it?
No, and we are not going to pretend that is an engineering argument.

Ronin NIJ 3 · In development
See the test
The next one stops a rifle round.
Full-face coverage has meant handgun protection. We put UHMWPE armour on the Ronin frame, shot it with 5.56×45 NATO, and it stopped the round, with little deformation behind the armour, which is the number that decides whether a stop is survivable.
A proof of concept, not a certified product: one filmed test at a private range, not an accredited laboratory. It takes a hundred preorders to put it into production. Reach a hundred and we build it; fall short and every deposit goes back.
