These are Authentic "Jantzen Sun Clothes", as the Original Tag Reads. This tag has been dated to 1944. Tag reads: Reg. U.S. Pat Off, Jantzen Sun Clothes, Size 34 Made in U.S.A. There is no fabric content on the tag. They are made of Sanforized Cotton Gabardine with a slight sheen to it. They are lined in a waffle weave cotton (see last photo). They have elastic waist with the Original draw string closure, both in great condition. There is a handy little coin pocket on the front. It measures 3" across and 2 1/2" deep. It has the Original Button. Men's Size 34. I have listed measurements below. They are in Amazing Condition. They are free of Mold, Stains, Tears or funkiness. In Great Vintage Condition, appear to not have been worn often. Feel Free to ask questions. Amazing condition for being 69 years old.

Measurements were taken flat:
Waist 12 1/2" as is, Stretched 17" so definitely 34"
Length 12 1/2"
Hips at it's widest 20"
