Want a bit of the ocean in your clothing or in your bed? Seacell is a fabric made out of Lyocell (a 100% wood pulp fiber) and seaweed. The theory is that your skin will absorb nutrients from the seaweed, which is quite mineral- and vitamin-rich. From what I can gather, Seacell incorporates 5% seaweed content. The manufacturer, Zimmer AG, says that the porous, open structure of the Seacell fibers “breath” well and absorb what your skin expels. Seacell is mostly being used in bras and underwear, but it also being used in bedding.
