The ScubaPro Definition also claims to have infrared-reflective lining. And, I think, even though it doesn't say anything about infrared-reflective, the ScubaPro EverFlex is supposed to be even warmer than the Definition.
Personally, I would not go from a decent 7mm to a 5mm with "infrared-reflective" in any brand. I think all of the top name brands have top of the line suits that are warmer than their low end suits. But, I don't think any of their suit lining technologies are enough to replace 2mm of neoprene.
Specifically regarding the Bare Reactive, I have heard several stories of problems with their zippers. My shop owner says it's not the zipper, per se. He says it is that the suit material is so stretchy and the design of their inner spine flap is such that if you try to zip the suit up by yourself, you'll end up frequently having stuff catch in the zipper and eventually tear stuff up. He said that if you always have someone zip it up carefully for you, it would be fine.
Personally, I'm just looking for any excuse to get a new ScubaPro EverFlex 5/4. It is fully lined with their DiamondSpan lining. I have a pair of their boots with that lining and they definitely seem very warm. I expect the Bare and the EverFlex would be equally warm (assuming equally good fit). But, I have 3 EverFlex suits now and never a lick of trouble with the zippers.
