Shoulder length nitrile gloves
I used to not enjoy getting my pond ready for winter because I had to dip my hands, sometimes up to the elbows, in the cold water to pull the pots etc. out to trim the stalks and leaves off and to clean the pond of leaves and other debris. I found these shoulder length nitrile pruning gloves that work great to keep my hands from touching the cold water.
