About Pima Cotton
Made in: Peru
Impact Score: B+ | Good
Combines sustainable and recycled elements. Reduces harm compared to conventional fibers but includes non-biodegradable synthetics.
Landfill time: Cotton Portion: Biodegradable within ~3–12 months.
Synthetic Portion (Spandex/Elastane): 20–200 years, depending on soil oxygen levels.
What We Love:
Organic; grown without harmful pesticides or synthetic fertilizers.
Local "seed-to-garment" approach significantly reduces carbon footprint.
Naturally soft, durable, and fully biodegradable (cotton portion).
Fabric scraps from cutting are bundled and re-purposed into mops, rags, and mattress fillers, ensuring a circular supply chain.
Pima requires 50% less water than conventional cotton; naturally drought tolerant.
Spandex adds comfortable stretch for fitted everyday wear.
What We Don't Love:
Although our raw cotton suppliers employ regenerative practices, they are not officially certified as regenerative.
Spandex/Elastane is a synthetic polymer that does not biodegrade and contributes to microplastic pollution.
Blending cotton with synthetics extends landfill time and limits circularity.
