About Minus33

Minus33 offers the finest quality Merino wool base layers & apparel at a price that everyone can afford. Carrying forward over 108 years of wool garment manufacturing expertise, Minus33 was created by the wool experts of the former L.W. Packard Co., in 2002, as a response to the changing global trade and manufacturing landscape. In 2020, the brand set out to bring wool production back to Ashland, New Hampshire, with its Mountain Heritage line of socks, extending a local tradition dating back to 1840, when the Briggs brothers of Leeds, England, built a woolen mill on the Squam River, manufacturing wool products, hosiery, gloves, sporting equipment and paper. In 1916, Luther W. Packard of Berwick, Maine, purchased the mill and named it L.W. Packard. For more history on the L.W. Packard Mill and Minus33, read Our Story.
