Where can you buy clothing for Antarctica?

If you're shopping for your tour, you are best directed toward a mountaineering vendor that sells layers. Ask your tour operator for extremes in weather and temperatures, so that you can be prepared.

If you're preparing to work temporarily on the continent, buy layers, personal underwear and clothes you'd wear indoors in rooms heated to about 50 degrees. As part of your deployment, your government will issue you relevant extreme cold weather gear, which you turn in when your work there is finished.
