US Army P.O.W. or better known as Prisoner Of War denim style ball cap - used during the WWII by the Gi's who re-made the cap using Daisy Mae hats.
Made with 10oz raw denim shrink to fit in size 60" (Large Size) when washed in lukewarm water they will shrink to about 57/58". I suggest to soak them in water for 20min. and then rinse out excess water; wear it on for few minutes when wet to adjust to your head size.
Now available in Medium 55/56 size.
*they run a little bigger than the Daisy Mae hats.
