J. Marin Co.
Organic Cotton Thermal Lounger Sweatpants
Our Organic Thermal Lounger Sweatpants are a nod to classic ‘70s leisurewear. With a softly structured straight-leg silhouette, elastic cuffs, and a drawstring waist, they offer both ease and quiet charm. Cropped at the ankle for effortless comfort.
Crafted from a cozy, USA-milled 100% organic cotton box thermal, the fabric is mid-weight—perfect for year-round layering. Contrast stitching in vintage pink adds a playful, nostalgic detail.
Pre-washed for a lived-in feel that’s soft as a baby blanket.
Thoughtfully designed and sewn in sunny California.
Care: Wash cold. Wear often.
