I have had my Lost Worlds J23 since February and while it was breaking in nicely, I started to notice that the chest was a bit baggy on me. Also I didn't like that when I zipped the cuffs they were fairly loose. I found the quilt lining too warm as well. I contacted Alan at Johnson Leathers. Alan swapped out the quilt lining for a very nice sateen, he took almost two inches out of the chest, about 3/4 inch out of the cuff, and added a snap at the bottom of the jacket to protect the zipper. Just got the jacket back. It turned out amazing! If you need alterations done, you can trust Alan. Alan was very professional, took the time to listen to my dislikes, and perfectly addressed them for a fair price. Total time including shipping was about 3.5 weeks turn around. Excellent!
