I always ask myself what I'd like to be wearing if I jumped out of my car between 25 and 85ish.. I don't always follow that but if spending money on protection that shirt wouldn't be high on tha list.
Itchy as hell. Maybe new draggin's are lined. Original, even when worn over a long sleeve tee itched too much for me. Got mine 7-8 years ago, gave it to a friend after trying to wear it several times. He gave it away to another friend and I lost track, you probably could get it cheap at Goodwill.
I wear Kevlar jeans in the summer I don't think they or not to hot never have tried a Kevlar shirt but I am thinking about a nice textile jacket as I get older I relize I am not bullet proof any more
