Francesco,
Personally I prefer artificial suede than natural. The artificial, like ALCANTARA, is not that delicate as the natural and will have a longer longevity.
The other quality of the artificial suede is that the material will maintain his form.
The leather shall have an easy deformation with the fast switch over from warm to cold.
And don’t forget the rain. Leather is not made to combat the rain.
The only way to make leather impermeable, is to spread wax on it. That’s not fine for the clothes.
ciao
