Airsoft clothes/camouflage: Its good with warm and good clothes if you play airsoft because if you are playing a big milsim game in the woods you may get dirty or wet. But you should not wear shorts or thin pants with no protection, if you get shot in the leg while wearing shorts it can be very painfull.
when it comes to camouflage you probably want to wear something that fits in with the envirement your in. If you are in a snowy area you may want to wear white camouflage or if you are in a hot deserty area its probably best to wear tan camouflage or black.
