Best bang for the buck is Kinco Alyeska rag wool gloves.

They have a fleece/wool blend lining and are available as gloves, half finger gloves or convertible mittens. Good fit around the wrist. The convertible mittens do use magnets which I like. Velcro is too noisy for me when bowhunting in a treestand.

When it rains I use a thin gtx-like mitten over.
