I received my shipment the Atlas 720 gloves today. The material looks very promising. Unfortunately, the sizing will likely be a dealbreaker for me. I wear the XXL 660, and the XXL 720 is cut differently. The fingers of the 720 are shorter, and the overall feel of the glove is smaller. I can jam my hand into the 720 with the Xerotherm liners, but they are more than likely too tight offer any benefit over the 660. They weren't a huge investment, but I'm pretty sure I'll return them and stick with the 660.
To get this thread back on track with insulation, I have some liners from Mountain Hardwear that are pretty light, some newer style liners from Patagonia that are OK, but not as warm as the old school fleece liners from Patagonia that I have been wearing for many years, and I just picked up the Fourth Element Xerotherm liners. They seem very nice and fit well, but I'm struggling to find liners that they fit in. Depending on the size of your hand, YMMV. I have had OK luck with rubber dry gloves, but if you get a hole in one during a dive, there is a much greater chance of catastrophic glove failure than with any of the gloves that have a fabric support lining in them. I've typically chosen my liners based on the fit and finish of the seams and the bulkiness of the liner. The name brand gloves seem to be finished cleaner than some of the cheaper gloves. YMMV.
