As a person who is usually always cold, I could not disagree more. The problem with layering is as follows

1) It actually isn't comfortable. Put on 3 or 4 shirts with a few pairs of pants. You have sacrificed one comfort for another.
2) It causes me to sweat and if I am not bundled up enough it then cause me to shift right back towards being cold. What a suck fest :P
3) As a person who needs to type all day long to do my job, I can't wear gloves (not that gloves have ever helped all that much in the first place. Mittens or GTFO).

I also feel the need to say that my core is never cold. Just the arms, feet, hands and legs. I have never understood the point of a vest. It warms up the area that never needs warming :/

Being cold all of the time makes me not want to do work because I am more focused on staying warm. Under a blanket, with added layers and blah blah blah. To do my work I have to removed myself from this. Long story short, only one side wins the comfort game.

All of that said, there is a solution to all of our problems! http://www.wired.com/2013/10/an-inge...o-ac-required/ how awesome is that?
