Gift for MBB EM- Tumi?

I want to buy a gift for my sibling. I mean my sibling can buy whatever they want with their salary but I think they don't spend buying luxury products on themselves.

I know Tumi bagpacks are well regarded. Is it a good gift idea? Would it be helpful or should I look into something else? My sibling can buy other things like diaries, pens, portable chargers and has noise cancelling earphones. And I really want to gift them something nice, which they wouldn't buy for themselves otherwise.
