Sizing not listed as correct size on plastic packaging. The plastic sticker says it's large, but the inside is medium. Barcoded Champion Pants with Medium markings are simply not packaged as such. No wonder they didn't fit. I had to rush to order a replacement (the military son was going back) and ordered an XL thinking the first pair was the same as the label (large). Luckily the XL arrived just in time and was a good choice as the pajama bottoms fit snugly around the legs.
