In Edmonton, student Josh Le, 20, told Postmedia News he bought the denim jeans in September 2009 and wore them daily -- and sometimes slept in them -- until last December.

Every two weeks, he said he put the jeans in a freezer overnight and there never was a trace of odor. At the conclusion of the experiment, he and assistant human ecology Professor Rachel McQueen ran tests on the pants and found bacteria levels were the same as any other samples, the report said.
