All Twinberry products feature Coolcore® fabric—a sustainable and chemical-free fabric. Engineered to distribute moisture quickly throughout the garment, our products eliminate any sweat spots and dry much faster, keeping you cool and comfortable. Reasons we love Coolcore fabric include: chemical-free technology, performance that doesn't wash out, recycled yarn-based fabric, blended with biodegrable fibers, no topical treatments, and sustainable mill practices.
