Quoted By:
I use a pair of poly under gloves, the kind cyclists often get, because they avoid moisture getting trapped in your gloves. Damp gloves don't insulate shit.
Then options:
There are these cheap gardening gloves for fruit pickers, ag workers, which are elastic and full of insulation so they fit really well. Water resistant but not strictly water proof. There are wool mittens, which aren't water proof but perform fairly well when wet, so if it's likely you can't avoid water, that's a consideration. Thick poly gloves like wetsuit gloves are probably better overall, i have some for sailing, then there are ski gloves, which should have removable liners.
