Rapha, nice but a bit pricey?

Whats the difference between a regular sleeveless baselayer and an italian one? I presume skinnier fit?

The Italian base layer has the Pantani quote on it instead of the Lapize quote.

Lifted from Rapha site:-

• The white sleeveless version is available with choice of two slogans: VOUS ETES DES ASSASSINS , the famous exhortation from Octave Lapize after his 1910 ascent of the Col d' Aubisque; and CARPEGNA MI BASTA, Marco Pantani's nod to his beloved Monte Carpegna, the training ground for so many of Il Pirata's victories.*
