I learned my lesson and go fully covered. Not because I have hot bees, but because I have a tendency to hack them off by blundering somehow or I may pick the wrong day or time of day to get in. I do not wear gloves anymore but they are with me if I need them. Same with a smoker... it's there, ready, if I need it.
The bees seem to leave my hands alone ... kow!!! For now anyway.
Since my clothes are home made I will drop to a just a jacket with attached hood, when I can afford it.
