In initally I thought of this idea for babies sleeping bags, but on reflection I decided it'd be just as suitable for all sleeping bags, basically the idea is this: You have standard sleeping bag which is modified so that there is a vent at the bottom. A thermostat inside the sleeping bag can open the vent if the temp rises past a user specified level, and can close it if it falls below it. The TOG rating of the bag could be slightly higher than usuall to help it warm up quickly and if appropriate a low power fan could come on in the vent to assist in the cooling if required. It'd probably only need a couple of AA batteries run and could make that camping out experience just a little bit more comfortable.

Does TOG stand for anything? I can't think what but it sounds like an abbreviation.

apparently //Tog is a measure of thermal resistance, commonly used in the textile industry, and often seen quoted on duvets. A tog is 0.1 m2K/W. Another unit of thermal resistance is the clo, equal to 1.55 togs//

personally I think it has to do with the slang word for clothes - togs
