With 33% more down and having the extra baffle in length, the magma is a longer, warmer version of the classic plasma jacket. As with the plasma, the magma jacket keeps its two generous chest/hand-warmer pockets, its two internal drop pockets and 8 oz (225 g) of ethically-recovered 860 fill-power Polish goose down.
