Wear More, Wash Less
Machine washable. We recommend the delicate cycle with like colors and cold water. Air dry or tumble dry on a low setting. It's best to wash these items separate from abrasive items like denim, towels, or items with hardware (zippers, buttons) as it causes unnecessary wear and tear.
Impact Score: B+, good. Blends sustainable and recycled elements. Reduces harm compared to conventional fibers but relies on synthetics that are non-biodegradable.

USDA and GOTS-certified organic.
Grown without harmful pesticides or synthetic fertilizers.
Local “seed-to-garment” approach significantly reduces carbon footprint.
Extremely durable due to hand harvesting.
Requires 50% less water than conventional cotton.
What We Don't Love:
Although our raw suppliers employ regenerative farming practices, they are not officially certified as regenerative.
Spandex/Elastane is a synthetic polymer (plastic).
Since spandex persists in the environment, it contributes to microplastic pollution when broken into smaller particles over time.
