He also managed to have a successful career with the Italy national team, notably winning a bronze medal at the 1928 Summer Olympic Games;[1] he was also a member of the Italian side that won the 1934 FIFA World Cup.

He received his first cap on 15 January 1922 against a strong Austria side, in Milan; he was selected in place of Virginio Rosetta as right-back flanking the great Genoese left-back Renzo De Vecchi ("Son of God" to the fans), who had been playing for Italy since 1910.

[2] After winning a bronze medal at the 1928 Summer Olympics, Caligaris left Casale to join Rosetta at Juventus, making his Serie A debut with the club on 6 October 1929, in a 3–2 home victory over Napoli.

Here the two full-backs, backed by Italian international goalkeeper Gianpiero Combi, and with centre-half Luis Monti in front of them, formed a formidable and successful defensive combination.

A strong, hard-tackling, and tenacious player, he was known for his pace, work-rate, stamina, and his ability in the air, which he combined with an excellent technique.
