Bought this suit recently and feel it is better than Clam's Ice Armor and X Armor. Everyone in my group has the original blue suit, except one guy who just purchased the Gray Suit. (due to me purchasing the Red Suit) The IDI Gear Suit is very similar to the blue one, except it has built in gators in the bibs to protect against any water/slush. Yesterday, I sat in my backyard for about an hour, temp was mid 10s, mild wind....no problems with being cold, but you'll want to use the two sets of draw-strings in the coat to block wind from going up your back. As far as sizes go...follow the chart on fish307's site. It is fairly accurate.
The Gray X Armor suit is ok too, but because the bibs are convertable to pants, you have to zip 'em twice. Also, the inner coat is a nice thought, but it makes the coat heavier and feel a little snug. Besides, I never have had any temp. issues when wearing a thermal long sleeve shirt, hoody and regular winter coat before. Then again, I have a shack and heater if things get real bad.
