Can't talk for anybody else, but I have used my gear PLAYING AIRSOFT... From rolling in dirt, in the rain, through the woodland/rocky terrain for 24 hrs to needing to cut myself out of thick branches because I had to roll down the big ass hill to avoid enemy detection/flank them. Digging and building fortifications, once again in the rain, in the dark, under enemy fire. Halling ass through waist deep swamps and rivers. Spending night in close to sub zero temperatures in the field. And staying effective for the fight.
It all depends on how, where and with whom you play. For some gear is a cool accessory they can display to friends and worry about a spec of dirt on it. For others it is a tool and meant to be used.
