Welcome to the forum @Remy.
I imagine a stick of Tabac is pretty handy to take in luggage and even if the scent might not be for everyone it's a great soap.
Aside from MWF & Tabac, another classic soap which seems to go under the radar a bit here is Cella.
HOWZIT!!
you could take some Phoenix & Beau, OSP, and Wickhams.. Brit soaps with lekker reputations..
Thanks for the welcome and the suggestions. Will have a look at Cella, haven't come across it until now
Shot bru Awesome, will have a look at these soaps as well!
