Is there a luggage manufacturer who makes a suitcase with zip off cabin luggage?

Question

I would like a Suitcase no bigger than 158cm combined measurement. And a cabin bag with a maximum length of 56 cm, width of 36 cm and depth of 23 cm.
I am in the UK.
Ideally I would like the cabin bag to be attached piggy back style with a zip to the main suitcase.

I have searched extensively on Google and can't find any.

Answer 1

None that I have come across. The ones closest will be those that ride on top of the main trolley case. Seen plenty in Hong Kong malls.

Answer 2

I don't know about suitcases, but you can get backpacks with small day packs that zip off. Check travel shops or STA travel.
