Linen

Linen is a bast fiber spun from the stalk of the flax plant, and the traditional retting and mechanical processing that separate the fiber introduce little in the way of residual chemistry.

Linen is one of the kindest fibers you can put against skin. It is highly breathable and moisture-wicking, pulling sweat away so you give bacteria less to feed on, which is why it reads as naturally antimicrobial and tends to suit sensitive and reactive skin. Cell-level cytotoxicity testing (whether a material kills or harms living cells) has found flax fiber non-toxic. The catch is marketing. Words like wrinkle-free, easy-care, and anti-static often signal a formaldehyde-based finish, a known carcinogen and skin irritant, layered onto a fiber that never needed it. You are paying for convenience with chemistry.

Choose OEKO-TEX STANDARD 100 or GOTS-certified linen, skip the wrinkle-free and easy-care finishes, and treat European Flax sourcing as a quality signal rather than a health guarantee.

Flax needs minimal irrigation and pesticides, and undyed linen biodegrades.
