Brooklyn-based Knickerbocker MFG. Co. has just launched two separate collaborations with Brooklyn Denim Co. and Schott NYC, each of which includes different takes on classic hat styles. Williamsburg-based Brooklyn Denim Co. lends its premium blue denim materials for the creation of these collaborative old-school style caps. Schott NYC stays true to its authentic American roots in this batch of fine leather-made hat styles, including work caps and bucket hats, which are elevated by details like herringbone cotton twill and horsehide leather trims. You can check out and buy the Schott hats on its website; the Brooklyn Denim Co. hats however are only available at its store in the Mill Building in Williamsburg.
