This article is part of our guide which airsoft helmet to choose.

What Is the Caiman Helmet?
The Caiman is a helmet made by Galvion and used by military units, recognisable by its high cut and rails built into the shell. Airsoft replicas copy its silhouette with materials suited to the game: they take BBs and carry your accessories, without claiming real ballistic protection.
The 3 Versions Available
| Version | Colours | Price | Who it's for |
|---|---|---|---|
| Solid colours | Tan, Dark Earth, Foliage Green, Ranger Green, black, Sage Green, desert | €181.99 to €192.99 | Plain outfits, low-key loadouts |
| Camouflages | AOR1, AOR2, Multicam, Black Multicam, Kryptek Noir and Highlander, ATACS, ATFG, ACU, Real Tree, Digital Desert, Digital Woodland | €217.99 | Matching the helmet to a camo outfit |
| Bright colours | Orange, blue, red, purple | €179.99 to €192.99 | Speedsoft, easily identified teams |
All three versions share the same stated specs: 520 g, aluminium frame, Roverson rails, repositionable inner pads and a quick strap-lock fit.
Which Size Should You Choose?
Measure your head with a tape measure, just above the eyebrows and ears:
- Up to 60 cm: size M-L.
- 60 to 62 cm: size L-XL.
Between two sizes, take the larger one: the repositionable pads take up the space, whereas a helmet that is too small stays uncomfortable.
Fitting Your Caiman Helmet
- Position the pads so the helmet sits straight, with no pressure point on the forehead.
- Put the helmet on one finger above the eyebrows, with goggles or a mask on your face.
- Tighten the strap lock until the helmet no longer moves when you shake your head.
- Adjust the chin strap: it should hold without hindering breathing or swallowing.
- Check in a firing position, cheek on the stock: the back of the helmet should not push forward.
Caiman or FAST AF-01?
| Criterion | Galvion Caiman type | FMA FAST AF-01 |
|---|---|---|
| Stated weight | 520 g | 1.2 kg |
| Size | M-L 60 cm or L-XL 62 cm | Adjustable from 52 to 64 cm |
| Colours | 23 colours and camouflages | 6 colours |
| Price | €179.99 to €217.99 | €73.99 to €96.99 |
The FAST AF-01 is the choice for budget and a universal fit; the Caiman for weight and looks. The full comparison is in FAST, MICH or Caiman.
Accessories for the Caiman
- Light and camera on the side rails.
- Visor: our GIGN/SWAT visor is designed for the rails of FAST and MICH helmets; test the fit on the Caiman's rails before the game.
- Patches on the velcro panels.
Spread accessory weight on both sides to keep the helmet's weight advantage.
Care
- Clean the shell with a damp cloth; no solvents on camouflage versions.
- Remove the pads and let them air-dry after a game in the rain.
- Check the strap lock and chin strap before each game.
