Anyone looked at this set yet? Supposed to be a regulated baselayer that maintains a consistent 98.6 deg. Body temp.....if this is true I will be super pumped. Pricey as heck though :-/. Also saw some Cabelas garments in their new pattern "O2 Octane". I'm digging it.
I think no different than wearing a good base layer like cold gear and then a merino wool sweater. A lot of the new stuff these days they sure are marketing the hell out of some of it. Granted I know technology is advancing but so much of this stuff is the same but with a different name.
