I was thinking of getting the medium im 5 10 and skinny but also have longer arms, I was just wondering if the medium would be big enough arm length wise?
A medium will fit you true to size, a large will fit you a little baggy. I'm 6 feet tall and also skinny, and rocked a large airblaster jacket last year. I wish I would have gone with the XL, so I'm gonna say that unless you want a really fitted look, go with the large.
