My body naturally gets very warm, very quickly, with very little exercise. If they can make this work, I might actually be able to wear a suit all day! Luckily I don't need to but that's beside the point. Assuming they can get the size and look sorted so the average consumer doesn't become a social pariah by wearing one (calculator watches come to mind), I wonder how this is powered? And more importantly, would it last for 8-12 hours on a charge?

If they're using Peltier devices it's probably going to require a largeish power supply, and some kind of heat dissipating/gathering device. One possible way to get around this for something like a suit jacket might be to move it from the wrist to the upper back, and to sew thin copper wires into the jacket. Also you could probably get away with having a few thin LiPoly cells placed in pockets around the jacket. Couple it all with an inductive charging coat hanger, and you've got a product worthy of SkyMall!

Isn't this related to fitness? If you're physically fit you don't get hot so quickly.

  It often is, but I'm in pretty decent shape. I cycle regularly (my commute is 34 km one way), am not overweight and eat decently. For as long as I can remember, I've always started sweating very easily.

  Is this actually true? I'm not calling you out, but I see it reported in comments all the time, but I've never read anything about it. I failed with a quick search. Beyond that, this whole discussion just went down in another thread, but I'm like the parent post...I just sweat easily. Even when I was younger in great shape (4-6 hours of basketball daily) I would sweat quickly and profusely. I read that some percentage (~15% I believe) of people sweat more than others.

  I haven't looked into any research about this, but anecdotally I find this to not be true. Having peaked at 215 lbs. and ~12% body fat at 5' 11", (I'm now closer to 195 lbs. and ~10% body fat) I'd say that I'm in the top 1% in terms of muscle mass. I am often very hot. My theory is that because of the added muscle mass (which requires much higher food intake), I'm metabolizing food at a higher rate and thus generating more heat. I don't know if this is actually the case, but it's my theory. This may not be the case for people who are fit in a more cardiovascular sense.

  I'm 6'1" and a solid 215 pounds. I do powerlifting and Brazilian jiu jitsu. I get hot quickly. I've had training partners tell me that I "run hot", that compared to others, I feel like a furnace.
