The CTAE collection celebrates the Commonwealth Trans-Antarctica Expedition (CTAE) of 1990, when The North Face outfitted a six-person team of scientists who crossed Antarctica to study the effects of climate change. The CTAE Expedition Parka is made of breathable and waterproof DryVent technology. It's filled with 700-fill responsibly sourced down. In terms of cut and style, it is very close to the original.
