Magma jacket


The Magma is our go-to jacket in winter. With 33% more down fill (225 g) and having an extra baffle in length, the Magma is a longer, even warmer version of our classic Plasma jacket.
Like the Plasma, it features two generous chest/hand-warmer pockets and two internal drop pockets.

Temperature Ratings

We don't give temperature ratings for our down jackets.

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.
