A leading lingerie company has joined Japan's fight against high fuel use, unveiling a heated bra for winter.

A model wears Triumph International's new thermal bra. The bra -- which can be heated in the microwave -- is the perfect choice for the woman who wants to stay both warm and environmentally conscious this winter.

The fluffy creation contains special pads filled with an eco-friendly gel that can be easily heated in a microwave or with a hot water bottle. Being padded, the new bra packs a little more bulk than most regular designs, but the Japanese arm of Triumph insisted the look was more chic than sheep.
