Turban
As per Guinness World Records,

“The largest turban is made with 400 m (1,312 ft) of cloth and belongs to Major Singh (India), a Nihang Sikh who wears the tower-shaped turban using over 100 hairpins, and 51 religious symbols made in metal.

This style of round turban is known as a dumaala and is common to Nihang Sikhs. Most Nihangs wear a smaller turban than this, but there is a tradition of competing to see who can wear the largest. Major Singh’s 400 meter turban weighs around 35 kg, or roughly 77 lbs. Nobody else is in his weight class, the next largest turbans are 10 kg smaller.”

But, Avtar Singh Mauni, 60-year-old resident of Patiala, is on the verge of a world record courtesy his 100 pound turban. When unwrapped, Mr Mauni claims, it stretches to 645 metres – almost the same length as 13 Olympic-sized swimming pools.
