If you have a few hives to get through its best to put one non powdered pair on over the top of another
You then just have to take the top propolised ones off and replace them
The synthetics are ok and there are plenty of powderless latex ones but if your hands are damp it is harder to get them on
they do save you lots of time cleaning the hands with surgical spirit and they are (relatively) cheap
