Is the Large Cuir the same as the Large in the regular Le Pliage? <<=
Depend which style in Le Pliage against Large Cuir
I have large cuir against large le pliage with long handle strap
a bit similar only cuir a tiny bit bigger due 'boat shape' just wait other chimes in
The size for the Le Pliage Cuir medium to LV speedy 35 are similar.
However the cuir medium is bigger than speedy 35 due the cuir has 'boat' shape (both sides) so slouch more like speedy 35, the difference is that cuir able carrying over shoulder from its handles if you have small frame shoulder whereas speedy 35 a bit structure and need long strap to carrying over shoulder.
See below pic are for reference between LV Speedy 25 and Le Pliage Cuir small size.
