Waterproof glommitts?

[jbird68]

I like fishing with glommits instead of gloves. But once mine get wet my hands get cold. They well soak up water just from unhooking fish I bring up through the hole. I've seen some in the local Farm and Fleet. But they didn't have a slit in the thumb so I could user my bare thumb to tie my line. Anyone know of a good place to get a pair that are waterproof?
