Pajama Jeans. WTF.

I don't understand this product. Honestly, the first time I saw the commercial, I thought it was a SNL sketch (a la "mom jeans"). But apparently, this is for real. Has anyone actually touched a pair. What in the hell are they made of. My favorite part of the ad is where it tells you they're "perfect for travel, exercise, shopping and more!" Really - exercise jeans? THAT is something I would like to see happen at the gym. Will they make skinny pajama jeans? Different "washes?" This is like the Snuggie for 2011. Which means I may have to purchase a pair. We'll call it "research."
