You can never have too much of a good thing and the same thing applies to denim jackets.
But if you do feel that enough's enough and it's come the time for you to have the one jacket to rule them all, then MM6 is a great place to start. And finish.
Their Denim Sports Jacket is nice for a range of reasons. It's crafted with a midweight, 100% cotton denim (making it rather sporty as it's name suggests I imagine) and its design loosely draws inspo from the Type 2 jacket, which is evident in its pocket placement and button down style. Loves a cheeky reference.
Whether you choose to wear it buttoned up as a shield from the world or undone to flex your under layer, the choice is all yours my friend.
