Camouflage & Skrim
Airsoft is a tactical game where skill and strategy are important, but so is the ability to blend in with the environment and not be seen by your opponents. This is where camouflage face paints and creams can prove to be really useful. You can get replica camouflage helmets to cover the head, while scrim scarves will hide the wearer, while still enabling them to see out, which is extremely handy for those with sniper rifles.
For the ultimate in elusiveness to make the wearer blend in seamlessly with their surroundings is the ghillie suit. These camouflage netting suits are designed to keep the player out of sight when playing in woodland settings.
