This is a pretty sweet vintage (circa 1970s) adult medium nylon DEW CREW jacket.
It's old, but still in solid shape (though a bit wrinkled).
The only really noticeable issues are two small holes that appear to have been created by hot ash. Take a look at the pics for a better idea.
Specific Measurements:
45" chest (22.5" armpit to armpit)
43" hem circumference
26" length (from top of shoulder to hem)
31.25" sleeve outseams (from edge of neckine to end of cuffs)
20" sleeve inseams (from armpit seams to end of cuffs)
I'm not really sure what this is worth or how much I can get for it so feel free to post or pm me your offers.
