Interested in ideas on layering gloves for winter camping.

Just got back from a 4 dayer in Snowbird Wilderness Study area near Robbinsville North Carolina. Nice winter conditions, plenty of precip but temps only down to mid-20’s. Found out my glove system - My Zpacks vertice XL rain mitts could barely be pulled over my XL Black Diamond Windweight Convertible Mittens, so they effectively couldn't be layered. The mittens are polartec and the four fingers stick out and have a mitten part that can be put over all the fingers. I like having my four fingertips available to use while keeping the palm, wrist, thumb and first finger joints gloved when I'm in camp for setting up eating, camp activities in general. Also useful on the trail.

Once the pollartec got soaked, it wasn’t nearly as warm. I ended up hiking in just my Vertices rain mitts, but if it had gotten really cold in camp I would’ve been hurtin’ without the constant motion of hiking to keep my blood pumping and extremities warm. Vertice rain mitts alone probably won't be warm enough for me for hiking either if the temp drops into the low 20's plus wind, let alone into the teens.

One of the guys had Black Diamond waterproof overmitts which seemed huge and would go over my Black Diamond mittens (first layer), and that’s what I’m thinking about trying next.I also have a pair of XXL neoprene “Hydroskin” brand gloves. They’re a little snug which gets cold - I think my extremities are a little cold, and after my polartec mitts got wet, more leaning towards a shell that can keep them dry, at least to play with next.

Just wondered now other people do it, and any specific ideas or things to consider.

Thanks.

So many thoughtful responses - thanks! Lots to process, will take me a moment. Yes, optimally I would've tried my overmitts before going. Just didn't - fortunately, live and learn. Found I have a pair of MountainLaurelDesigns overmitts, which do fit over my fleece gloves above, so am going to try those next. Looks roomier and the seams seem better designed than the Zpacks Vertice rain mitts. So much helpful info here - I appreciate y'all who responded!
