"A designer is launching a range of underwear - made from bamboo.
It is pulped and then spun into fibres to be woven and dyed.
It is said to be more eco-friendly than cotton because it is quick to grow, does not need pesticides an it is biodegradable. The undies are soft and strong, and cost from around £30.
