This iconic moto can be classic in a Smooth lamb without the contrast plaid undersleeve, or you can have it in an updated Bubble lamb and with the lumberjack wool that is both retro and modern.
You might only be looking for a classic motorcycle jacket in an all-smooth lamb leather. Maybe you're beard is growing in and think an extra-strength touch of a Red & Navy outdoor plaid will be enough of an update. Not enough, go all in with the updated Bubble lamb that gives the jacket, and perhaps you, a little tougher character.
Make the choices in leather and whether you want the plaid undersleeve. Then pick out a lining that is more suitable to your adventures on the road. The fit isn't a loose cut, so if you want a little more room than the model, buy a size up and you'll be able to take down that second or third serving of apple pie.
