When the Jews were expelled from Israel in Roman times, they wore turbans similar to the Arabs. While in Europe, under cold climates, the SWITCHED their tradition to wear those hats, shtreimels etc.
Why, when the Jews, after 2,000 years of torture and death, returned to Israel, not SWITCH back to headgear more suitable to a hot climate?
As a rabbi once told us, it’s not a mitzvah to sweat !
