Carhartt Men's Wp Waterproof Insulated Mitt Cold Weather Gloves

Q: Is the lining open inside as a "true" mitten - or does the lining separate the fingers?

June, Hi. The lining is open inside like a true mitten; it does not separate the fingers. I find these gloves to be quite warm. The only minor issue I have with them is that sometimes my fingers will sweat inside the mittens and I need to make sure they dry completely before wearing them again.

Q: Has anyone tried these gloves with double rag wool mittens inside as liners? Is there room for them?

I imagine it depends on the size of you hands and whether or not you can oversize the Carhartt gloves enough to accept the added bulk. I would put on the rag wool mittens and check the sizing with them on you hands. Then check the size availability of the Cahartt gloves. Good luck.
