The Coldgear fabric is much thicker. Go with the Mock for top and whichever leggings that you think you need. Looks like the Inferno is the warmest. But I gotta tell you that your legs are the least that get cold because it's well protected by the fairing so that it's not as exposed to the cold wind as your torso.

Granted that I'm a fat dude with lots of natural insulation, but my riding get-up for the Cali high desert (which runs into the mid-20s) are Coldgear compression long sleeve Tee, Coldgear leggings, full leathers, UA balaclava under full face helmet. Gloves are dependent on which vehicle I'm taking. If it's the Beemer with the blister hot heated grips then just the regular leather gauntlets (no perforations/ventilations). If it's one of the other bikes, then it's the Cortech Winter Scarab - with a pair of silk glove liners on the side for just in case the gloves aren't warm enough.
