EXCLUSIVE! In National Lampoon's Christmas Vacation, the Griswold's Cousin Eddie shows up in a 1972 Ford Condor II RV-and wears out his welcome in minutes. In contrast, you'll wear these official holiday lounge pants decorated with wreaths, mistletoe and the infamous RV constantly and never get tired of their soft, hilarious presence. Machine wash. Elastic drawstring-waist pajama pants are 100% cotton. Imported. S-XXL.
