Vintage 1983 He Man Masters of the Universe blue & gray long sleeve sweatshirt & sweatpants set or pajama set.  Sears Boys brand size L (7)--fits 46 1/2 to 48 1/2 inches tall.  Please be aware that most vintage clothing sizes tend to be smaller than current sizing charts and this may not fit like a size 7 today.

New, sealed, never opened.  Could possibly have a musty smell due to age, but nothing detectable from the closed packaging.  Every thing looks perfect inside the bag (no holes, stains, or fading) based on what can be seen without opening the bag.

Please note that I am unable to give much more information/measurements or guarantee exact condition without unsealing the bag.
