Slim folio case for 13” MBP

I use a Tom Bihn Daylight and Cache as my everyday work bag. I love them both but would love to replace the Cache laptop sleeve with something slimmer.

I don’t need a lot of protection and prefer the case fit snugly on the device. Not a fan of leather. Hoping to stay around $50 or less.

I have the version of this for the 12” rMB. It provides enough protection for me and is very slim, but it’s a sleeve and not a folio case.

I haven’t used it myself, but I’ve been thinking of purchasing a Booq Superslim bag.
