Just keep away from spats, highly dangerous. I would also caution against the wearing of mits or chainsaw gloves they too can be highly dangerous as once they are wet and they are covered with lichen they become dangerous as the mits lose their grip and become slippery.............you try and holding on to something that wants to kill you with slippery gloves, if they don't come wet by the rain/dew/fog then they will become wet with sweat.
I always use the yellow rubberised cotton gloves just to take the vibration out of the saw and once they are wet I put another pair on or wear none at all.
Cheers.
