DEEP SEE dry comfort

[JcoldwaterIL]

I'm thinking of buying a pair of the deep see dry comfort gloves but had a few questions for those of you who have used them. Most of my diving is in the misdwest so between the quarrys and great lakes the water temps will normally be between 60-30 degrees year round. My hands get pretty cold using regular 5 mil neoprene gloves. Does anyone know if the deep see comfort dry gloves are actually dry, or just semi dry like some wetsuits? they are 4mm but ive heard people say they are much warmer than a typical 5mm. I'm looking for a decent glove to go back and forth between wet/dry suit diving. Also soes anyoen knwo how hard they are to don/doff compared to a typical wet gauntlet glove?
