It’s crazy that we’re so reliant on cotton for our natural fibre needs, given that it’s environmentally heavy and requires massive amounts of water. Give me wool any-day. Or banana fibre, especially now that aussieBum have launched a new range of men’s underwear in this unique fabric. Banana fibre is made from the bark of the banana tree and possess wonderful properties for undies: it’s soft, smooth and comfortable. In fact, it feels just like cotton. But it’s much better for the world.
