You know what, I think our dear friend and my co-moderator (well technically he’s keymaster and thus my boss 🙂 ) Terry_42 will have something wise to say about things.
Yeah I used my now destroyed (thanks doggy) Magma backpack as handluggage.
However I was flying what they call “premium economy”, so they cut you some slack on bigger handluggage.
The backpack did also fit my laptop and some other stuff.
The good thing is the TM8 is not that wide so it still fits in that measure thingy, I think with a wider unit like an SX you would have a problem fitting it in.
