Proto EL switch or FS switch. With the EL buy a thermal lense with the FS it comes with.
For airsoft id suggest some ess with a fan Full face isnt reall needed for outdoor airsoft and if you want it get a mesh lowwer so you can still use your sights on your gun.
For all the above id still suggest a good antifog as even the thermal lenses or ess with fan will get fog or condensation at times so a good anti fog will help with that. Fogtech works well also there is this stuff that comes in a paste kind of form smear it on let dry buff off (cant recall the name paintball places have it tho.)
