Line Dried Linen
2-in-1 Bio-Based Laundry Soap · 64 oz
A better way to care for what touches us every day.
Line Dried Linen is our fragrance-free, non-toxic, bio-based laundry soap designed to clean and soften in one simple step. Made with thoughtfully chosen ingredients, including microalgae oil, the concentrated formula is biodegradable, gentle enough for babies and strong enough for everyday stains.
Inspired by the quiet ritual of laundry drying in the French countryside—fresh air, clean linen, nothing unnecessary.
Clean + soften in one step
Our 2-in-1 formula cleans fabric while naturally leaving it soft, simplifying the laundry routine without the need for a separate fabric softener.
