The first pair of atomically flexible sleep pants.

Atomically flexible? Yes. If, like Ant-Man, you have the ability to increase or displace mass, you'll need clothing to increase/displace mass in tandem.

And, if you're displacing mass to sleep in, say, a doll house, it would make sense to wear the Ant-Man Pym Tech Unisex Pajama Pants -- they feel equally comfortable at 6 feet, 65 feet, and 6 inches.

Made from extremely soft cotton, these heather-gray Ant-Man pajama pants sport the official PYM TECH logo in bright red print.

Below the symbol, the official company logo rendered in sizable 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 teenagers experimenting with wrongfully procured Pym Particles.
• Spacious pockets.
