X-UnderGear

reddot design award winner 2005 and I can see why, how many of you have had cold privates in the winter, run with socks in your pant, extra padding, well this should help. X-UnderGear have thought of everything from the "ribs" that protect knees from the cold even when they are bent. In contrast to conventional underwear, X-UnderGear can effectively prevent loss of heat from the elbows and knees. "X-UnderGear is the first underwear worldwide to incorporate 37°CCR-Technology. This technology is based on the observation that the body consists of different climate zones that react differently to physical exertion. Whereas some areas are highly prone to hypothermia (e.g. thighs, knees, calves), others quickly produce excess heat. Accordingly, this means the body has to regulate its heat balance differently in these different zones in order to
maintain an optimal core temperature of 37°C. For example, some areas typically perspire heavily and others quickly feel cold, while others do not." Check it out
