A seal fur thong from Greenland, made by Inuits, 18th century

During the 19th century Inuits in Greenland would have entertained polite company in their settlements while wearing a thong made of seal fur.

Traditionally known as a ‘naatsit’, the underwear is adorned with beads and would have been sewn together by a woman using strips of seal pelt.

It is currently on display at the National Museum of Denmark in Copenhagen as part of its animal-skin clothing collection.

Peter Toft, the National Museum of Denmark‘s Greenlandic fur clothing expert, told Ella Morton at Atlas Obscura the underwear would have been worn inside the homes of the Inuit – even in front of guests or when visiting family members.

It was obtained during an expedition to the Ammassalik settlement in Greenland in 1892 by Captain C. Ryder.

When leaving the settlement, the female wearer would have worn it under trousers.

The naatsit was the only undergarment the Inuit would have worn next to their bare skin and it was often decorated with beads of glass, with the seal fur turned outside.

Example have also been decorated with small pieces of fur in different colours.

Seals are found along the coast of East Greenland and are hunted by Inuits (stock image) for their meat and skin. Seal fur provides less insulation than caribou fur to prevents the wearer from sweating and causing the material to become damp, and later freeze in the cold

Cunera Buijs from the National Museum of Ethnology said: ‘When weather conditions permitted, the naatsit was often the only garment worn, both in the home and outside in the settlement.‘

These homes would have been built to keep in the heat, with a low corridor entrance positioned in such a way to cause warm air to rise from beneath the structure into the home, and stay there.

In addition to the naatsit, the National Museum of Denmark’s collection also features a diaper made from reindeer fur (pictured)

Many of these primitive buildings would have housed more than one family.

‘There does seem to have been a taboo against walking around outside the home only in shorts,’ continued Ms Buijs.

‘As soon as the Inuit men left their own settlement, they put on a pair of long trousers made of seal or polar-bear fur.’

Seals are found along the coast of East Greenland and are hunted for their meat and skin.

Inuits across the region, and into North America and Siberia, would have also made garments from the skin and fur of reindeer and caribou.

The severe conditions of the region means that clothes have to protect against the cold, wind and damp and seal fur, in particular, provides less insulation than caribou fur.

This prevents the wearer from sweating and causing the material to become damp, and later freeze in the cold, continued Mr Toft.

Women would clean the skin and remove all traces of flesh to prevent them from rotting, a pricess called ‘flensing’.

The fat would be scraped away on a board called a qapiarpik and the clothing would have been sewn together using a sakkeq or ulu – a traditional woman’s knife – and a needle.
