I guess I have pretty skinny arms! The sleeves flap so much that my arms go numb after a while. It's a really weird feeling! I did wear it riding for 2 1/2 years, so it wasn't all that bad I guess, but last summer I bought a Joe Rocket mesh and now I wear that whenever it's warm instead of my Triumph jacket. The Triumph jacket does have a lot of nice features and if I could do something about the arms I would wear it again.
