Dastar
A Dastaar (, dastāar, from ) or Pagṛi or Pagg , is an item of headgear associated with Sikhism and is an important part of the Sikh culture. Wearing a Sikh turban is mandatory for all Amritdhari (initiated) Sikh men and women.
Among the Sikhs, the Dastaar is an article of faith that represents honour, self-respect, courage, spirituality, and piety. The Khalsa Sikh men and women, who keep the Five Ks, wear the turban partly to cover their long, uncut hair ( kesh). The Khalsa Sikhs regard the Dastaar as an important part of the unique Sikh identity.
