Halo Themed Pajama Pants

I have been looking high and low for Halo themed pajama pants. For Christmas years back, I got Halo 3 pajama pants and I’ve basically worn them to death. I’ve looked in stores, online, and I can’t seem to find any anywhere. Any links that I do find are from years ago and don’t exist anymore. Help Please?

All I found were these http://www.cafepress.com/+halo+pajamas?utm_medium=cpc&utm_term=halo%20pajamas&utm_source=google&utm_campaign=entertainment%20apparel%20-%20us&utm_content=search-b

I did see those as well… but they were just Halo Shirts and plaid pants. I’m really looking for ones that have the halo logo, any of them, on the pants themselves as a pattern.
