In short

Buy the Solis Aegis MK-V ($199) for the classic helmet at the lowest Aegis price, in a choice of three finishes: a 1.8-second motorised faceplate, voice, touch and a two-button remote, about four hours on 4 × AA. For $10 more the Aegis MK-L ($209) opens in 1.2 seconds, runs about eight hours and adds a five-button remote that controls each light separately. The Aegis MK-XVII ($219) keeps those figures in a reinforced multi-layer shell and four finishes — the one to choose if the helmet will be handled often. The Sentinel MK-I ($189.99) is a different shape: a full-face shell with a two-position visor, a textured satin finish and a rechargeable cell. The Titan Prime ($386) is the largest and most animated, with a moving battle mask, rotating gear covers, red and blue LEDs and a voice changer. All five carry a five-year warranty.

Aegis MK-V — the classic, in three finishes

At $199 this is the entry to the range. Its faceplate lifts in about 1.8 seconds, with a split mode that moves the panels on their own, and it answers to seven voice commands, a touch at either ear or a two-button remote. LED eyes and ear accents run from 4 × AA cells for about four hours of continuous use. It is the only Aegis offered in Classic Red & Gold, Silver & Red and an all-black Dark Edition — three finishes on the same shell and mechanism, at the same price.

Aegis MK-L — faster, longer, and a better remote

$10 more buys the three upgrades that matter most on an event day:

  • Twice the runtime. About eight hours on a set of AA cells against the MK-V's four.
  • A quicker faceplate. High-torque micro motors, 2.5 N·cm each, open it in about 1.2 seconds.
  • A five-button remote. Separate buttons for the front faceplate, the whole helmet, the eye colour, the eye lights and the side lights — silent control of everything in a loud room.

It is the sleek, nano-style shape of the range, sold in a single red-and-gold finish, with an AI-assistant voice module that answers to eight commands.

Aegis MK-XVII — the flagship

At $219 the MK-XVII keeps the MK-L's 1.2-second faceplate, eight-hour runtime and five-button remote, and changes two things. The shell is reinforced multi-layer ABS — stiffer panels, less flex and a smoother metallic finish, yet about 12% lighter than the MK-V at roughly 1,130 g. And it comes in four finishes: Classic Gold & Red, Silver & Red, Silver & Black and Dark Edition. Brighter eye and ear LEDs also read better in daylight. If the helmet will be picked up, worn and passed around, this is the one.

Sentinel MK-I — a different shape for less

At $189.99 the Sentinel is the least expensive helmet in the range, and the choice is not about which is better but about what you want. It is a full-face shell with a two-position motorised visor rather than a lifting faceplate, driven by voice or a paired RF remote, and the visor moves freely by hand when powered down. Its finish is textured satin rather than gloss — closer to a vehicle panel than a toy, and much better at hiding fingerprints over a weekend. It runs on a built-in rechargeable cell, about four hours active.

Titan Prime — the most animated

At $386 the Titan Prime is the largest helmet in the range — 25.4 × 32.9 × 37.2 cm — and the one with the most going on. Its battle mask closes on command while the gear covers on both sides rotate, red and blue LEDs light the covers, antennas and forehead grille in time with the sound, and a voice changer switches on when you speak. Energy and Battle modes each run their own sequence of light, motion and audio. It takes five voice commands, touch panels on both sides or a 2.4 GHz remote, arrives fully assembled, and is rated for ages 14 and over.

Stands

None of the helmets ships with a stand. The Aegis Display Stand ($79.99) fits all three Aegis models; the Titan Helmet Stand ($110) is sculpted for the Titan Prime. Both carry the same five-year warranty as the helmets.

Choosing, in five questions

  1. Want the classic look, or a finish choice, at the lowest Aegis price? → MK-V.
  2. Wearing it for a whole event, in loud rooms? → MK-L. Eight hours and a five-button remote for $10 more.
  3. Will it be handled, worn and passed around? → MK-XVII, for the reinforced shell — and four finishes.
  4. Prefer a full-face shell and a satin finish? → Sentinel MK-I.
  5. Want the most movement, light and sound in one piece? → Titan Prime.

Frequently asked questions

Which helmet should I buy first?

The Aegis MK-V at $199 if you want the classic look or a choice of three finishes; the MK-L at $209 if you will wear it at events, because it runs about twice as long and has a five-button remote.

What does the MK-XVII add over the MK-L?

A reinforced multi-layer ABS shell that is stiffer and flexes less, brighter eye and ear LEDs, and four finishes instead of one. Faceplate speed (about 1.2 s) and runtime (about 8 h) are the same.

How is the MK-XVII different from the MK-V?

It is about 12% lighter, runs roughly twice as long (about 8 h against 4 h), opens in about 1.2 seconds instead of 1.8, has brighter LEDs and a five-button remote, and is built from reinforced multi-layer ABS.

Is the Sentinel rechargeable?

Yes. It uses a built-in rechargeable cell good for about four hours active, where the Aegis helmets run on 4 × AA batteries.

Do the helmets come with a stand?

No. The Aegis Display Stand ($79.99) fits the MK-V, MK-L and MK-XVII, and the Titan Helmet Stand ($110) is made for the Titan Prime.

What warranty do they carry?

Five years from delivery on all five helmets and both stands.
