The Sphere M12 helmet is a high quality helmet appearing in S.T.A.L.K.E.R.: Shadow of Chernobyl, S.T.A.L.K.E.R.: Clear Sky and S.T.A.L.K.E.R.: Call of Pripyat. It is a separate usable item in the last game in the series.
Background
A high quality, aluminum/titanium combat helmet with cloth camouflage used by Duty and the military, the Sphere-12 is perhaps one of the best available helmets, with slightly higher gunfire protection and psionic protection than its brethren. It comes by default with camouflage (US Some woodland pattern for military stalkers or urban for Duty). It is normally used as part of a combination that includes PSZ series body armor. Comes with electronics slots.
It is usually worn with a gas mask by stalkers, although variants with a simple faceplate are also common among military stalkers.
Appearances
Shadow of Chernobyl
It is an integral component of the Skat-9 military armoured suit and the Skat-9M military armoured suit.
Clear Sky
It is an integral component of the Skat-9 military armoured suit, Skat-9M military armoured suit and the PSZ-9d Duty armor.
Call of Pripyat
It can be acquired from Owl in the late-game, and the Military's outfitter, Lt Kirillov, will provide you one for free if you request an outfit when you meet him. Oddly, it becomes less common than the Tactical helmet afterwards, as Owl rarely has it in his inventory.
It comes with a 1st-gen nightvision installed, and can be upgraded to second and third generation NVGs, the only helmet which can - although it lacks the thermal imaging upgrade of the tactical helmet. It's anomaly protection options are limited compared to the other helmets, and even fully upgraded is obviously meant to be used only for combat.

Cut content
Originally, the Sphere M12 helmet was supposed to have an additional tier 3 upgrade: a target acquisition system, like the one in the binoculars. It is not known why it was removed.
Trivia
- The gas mask often worn with this helmet closely resembles the American XM40 prototype gas mask.
