The CTAE collection pays homage to the Commonwealth Trans-Antarctica Expedition (CTAE ) of 1990, in which The North Face kitted out a six-strong team of scientists crossing Antarctica to analyse the effects of climate change. The CTAE Expedition Parka harnesses seam-sealed DryVent™ technology for breathable-waterproof protection. It's loaded with 700-fill of responsibly-sourced down for warmth. Shape and fit wise, it's true to the original. It also has a celebratory anniversary logo patch. The main upgrade is that we're now using recycled nylon, putting waste materials to good use.
