thank you! that eases my mind a little bit. i wouldn't mind scratches, scuffs, or anything like that. Im worried about deformity, like stretching. like the jacket looking funny overtime because of shoulder stretches. but this answer is reassuring enough to wear my jacket with my backpack to work. thank you kind sir!No it won’t ruin it. After a while it will show wear where the straps and the backpack touch the jacket. I used to wear a backpack daily and I also wore a cxl aero jacket daily. Cxl shows wear easily.
Don’t worry about it. Isn’t the charm of a leather jacket that it will break in to conform to your body and your lifestyle? I wouldn’t want my leather jackets to look like new for forever.
