The Everlane Boxy Linen Shirt is a bestselling silhouette in one of the most responsibly produced linen fabrics available. Made from 100% Masters of Flax Fibre certified linen sourced exclusively from France, the fabric is grown without GMOs or irrigation and processed without waste through a fully mechanical extraction method. Third-party lifecycle analysis confirms this fabric generates 74% fewer carbon emissions than conventional linen—a difference that's verified, not estimated. The silhouette is deliberately boxy and oversized at 23.5 inches in length, with a clean front button placket that keeps the look from reading as shapeless. Tuck it into high-waisted trousers for a polished front, belt it for a more defined silhouette, or wear it completely open over a fitted tank or swimsuit. Machine wash cold, tumble dry low, warm iron when needed. Made at Everlane's Poong In factory in Vietnam.
