Montana Sweater Co. uses fibers from Montana bison, sheep and alpaca. The fibers are custom blended and milled into warm wonderful yarns. Original patterns are knitted by Montana knitters into sweaters, vests, cardigans, hats, FingerFree Mitts, shawls, purses and more. Soft suede labels and hand-polished deer horn buttons give all our Montana garments an authentic Montana signature.
