This crewneck is part of a brand spankin' new collection we're calling the Pigment Dyed Program. After testing dozens of washes, we chose fabric that's “prepared-for-dye,” which means that each fiber has a varying level of affinity to the pigment (translation: a perfectly worn-in, vintage look from day 1). Comes in men's, women's, and dog sizes (JK. But that would be cool). Absurdly soft and breathable tencel terry fabric. Summerweight (aka lightweight, no profuse sweating)
