There is a great strap that can be used to sling it around my shoulder.

It isn't much lighter than our solid rectangular case when empty, but the straps and padding make it so much easier to get around

Handling - Comes with (1) a pair of robust rubberised ergonomic handles that soft-click together like a jigsaw for secure handling and (2) robust shoulder strap

and I love the backpack straps I bought with it

However, make sure the straps are secure to the case

Strong and sturdy straps

Though, any tenor with a beefy neck brace, as the Zephyr from that era does, the neck doesn't fit quite as well as it could.
