They don't run tall. They run small for sure. A little less than two sizes small than Jiberish. I have some Jiberish hoodies in large on their way, so one they get here I can really compare. I think the zipper length on the 2XL PRS is right around 30-31 inches. Super short for an XL. Overall, the hoodie is super nice. If you PM me your email I can shoot you a few pics of me wearing it and you can really judge the size in the pics. I'm on my phone right now, so all I can do is email pics.
yeah i have that hoodie in 2xl. its not a very tall fit but its so comfortable. im 5 11 and its fairly baggy. its got some sick features too; zipper pockets, thumb holes and a zipper that sort of goes into a turtleneck instead of zipping up the hood.
