The brilliant and sick minds at aussieBum claim to have created what they say are sustainable underoos using fabric derived from the bark of the banana tree. (Technically, the banana tree is a plant, not a tree -- don't say you never learned anything from us).

Banana tree fiber is not the only component to these drawers; they're blended with organic cotton and Lycra, providing comfort for those times when you need to go work the banana harvest and you don't feel like wearing pants.

Safety tip: Do not wear your banana briefs anywhere near your local zoo's gorilla house or when you're having a sit-down with Doctor Zaius.

These monkey bottoms in "banana hipster white" can be yours for $29.
