One item that I have not seen beekeepers using and I wonder why... a sweatband/headband to absorb sweat rolling off the forehead and onto eye glasses essentially blinding the beekeeper.
It happened yesterday - it's very warm, I'm suited up with my jacket and attached hood/veil. In no time sweat is rolling off my forehead onto my glasses restricting my view as well as being very uncomfortable. While fumbling around trying to see what I was doing I received two stings.
Today, lacking a real sweatband, I tied a long sleeve t shirt's sleeves around my head before suiting up. I thought I would be overheating even more, however, even with temps higher today than yesterday I was comfortable, was able to see well and could take my time. I'm going to be adding a simple terrycloth band to my beekeeping attire.
