Carry on weight allowances keep getting less and less. By the time you account for the weight of the bag you’re not left with much more than enough space for a weekend away. I generally pack my chosen travel kit as checked baggage. If it’s one or two nights and I can get away with carry on, I will generally forgoe the shave gear. I’ve never lost a bag and generally carry travel insurance. While not cheap, all of my travel gear is replaceable.
