Swedish fashion giant Hennes & Mauritz on Wednesday launched an unusual range of colourful disposable paper panties for the summer season.

The Stockholm-based company said the knickers are designed as one size fits all "G-strings" and are sold in packs of three in black, green and red.

The panties have been designed by Camilla Thulin who told the Aftonbladet newspaper the idea could be extended to men in the future as "many guys don't change their underpants every day". The paper added that in a test wearers found the panties "uncomfortable".

"They are on sale now," said an H&M spokeswoman. "They are good to have in your handbag if something unexpected happens, if you lose your luggage, or you exercise and forget to take a change of underwear with you."
