Expedition Down Jackets
Plasma Jacket
£399
Including UK VAT.
The full-zip Plasma jacket is a lightweight, waterproof down jacket filled with 170g of ethically-recovered 800 FP Polish goose down.
Launched in 2008, the Plasma jacket heralded the introduction of truly weather-resistant down clothing. A technical masterpiece, it combined a direct-venting, air-permeable eVent shell fabric with welded box-wall baffles and the very best quality Polish goose down. A decade on, the Plasma still has no equals – it is a unique product. The outer shell is made from highly breathable and fully waterproof eVent fabric, and highly water-resistant Riri Aquazips are used throughout. The baffles are welded to the shell fabric, thus eliminating sewn seams and any need for taping (for more details on the construction of our down garments, click here). The detachable hood has a wired visor, but does not fit over all helmets.

Care & attention+
Down is a very resilient insulating material and, with basic care, any down jacket should last you a very long time.
There are two simple rules to ensure longevity:
1. Always store your jacket uncompressed in a dry, airy place
2. Try to keep it as clean as possible to minimize washing (this ultimately damages the down).
We highly recommend you hand-wash your down garment or, alternatively, use a professional service. You can download washing instructions here.
