The lining of my incase sleeve is starting to pull apart so I’ve been browsing etsy for something a little more durable and maybe a bit unique. Plus I’d like to have some cargo space for a charger and headphones. I’m leaning towards the denim number with quilted lining, safe and classy.

I have the same exact case as your first and second picture and I dig it. I was afraid the felt would stretch too much but it’s been OK so far. That denim case is really nice/unique though.
