Including UK VAT.
The Women's Plasma is a lightweight, waterproof down jacket, filled with 160 g of ethically-recovered 800 FP Polish goose down. 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. The detachable hood has a wired visor, but does not fit over all helmets.

Temperature ratings+

How warm you feel is completely dependent upon your heat output. You may be cooler sitting around in a very warm jacket at -5⁰C than when snow-shoeing in a lightweight one at -10⁰C.

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.
