It's time to show the world your latest invention.

You were invited to tout your new robotic iGrill® at the prestigious Stark Expo -- a massive media event/science fair celebrating advanced technological achievements and Tony Stark's latest (and ostentatious) Iron Man upgrades.

And, because you were granted a free booth, you were also granted a free, luxurious, self-aware sweet and your very own pair of Iron Man Stark Industries Expo Unisex Pajama Pants!

Made from an extremely soft cotton, these Iron Man pajama pants for men and women feature a Stark Industries logo on the left leg.

On the right leg, the official Stark Expo logo and credo rendered in bold (and subtle) vertical text.

More reasons why these lounge pants are simply the coolest:

• Soft? Oh, yeah.
• An elastic waistband with drawstring tie.
• Unisex sizing for all comers -- men, women, and perhaps teenage inventors tinkering with homemade Iron Man armors.
• Spacious pockets.
