A cat curled into a golden spiral, because that is what cats actually do. 1, 1, 2, 3, 5, nap. Math people and cat people arrive at the same joke from different directions.

Light, soft combed ringspun cotton in a unisex fit. It fits true to size, so size up for a roomier drape. Color range runs athletic heather, ash, natural, and white.

Made to order and shipped in 3 to 5 business days. Nothing sits in a bin for a year first. The DTG ink soaks into the fabric, so it stays soft and holds up wash after wash. Wash cold, inside out, tumble dry low.
