the only vital equipmentt is masks for players and anyone else within range of the markers. Or by putting something in between players and spectators to protect them i.e. netting. As common sense would suggest yes at least wear some layers to avoid the skin being broken by any hits. If you want to run around in your underpants shooting each other then feel free, just don't be surprised to if people raise an eyebrow if you are seen doing so
No, I won't be doing that, I wouldn't want to merge both of my hobbies at the same time, I will leave running around in my boxers in public to other days hahaha
i can't see me needed knee pads quite yet then, the only way I will be close to sliding along the floor is when my mask fogs up and I trip over something haha
