The expedition members had two layers of woollen underwear that were provided by the Norske Trikotagefabrikanters Forening (Norwegian Knitwear Manufacturers Association). The base-layer consisted of a thin woollen shirt and long pants of the same material. Outside of this was a thicker layer of wool on the legs and an Icelandic wool sweater.
An outer clothing layer combined long trousers with a hooded windproof smock, sewn by Martin Rønne from fabric provided donated by A/S William Schmidt, Oslo.

Footwear:
Several options were offered. Amundsen, Omdal and Feucht preferred felt boots with a pair of thin socks, outside of which they wore canvas boots filled with sedge grass (an idea borrowed from the Sami people). Ellsworth and Dietrichson took short kamiks. Riiser-Larsen took thigh-length rubber boots. Everyone also took ski boots for a possible journey across the ice.
