Green Mountain Knitting

About Green Mountain Knitting

Green Mountain Knitting was established in 1985 when Calko Group moved part of its Canadian operation to Milton, Vermont, to serve the U.S. market. The division relocated to Swanton, Vermont in 2022 and operates under the corporate name Calko Group, which was founded in 1954. The company specializes in cut-and-sew and specialty knitting, producing knit trim, industrial wear, first aid and PPE, sportswear, and fabrics. It operates a vertically integrated model with 250,000 square feet of manufacturing space housing over 500 sewing machines. Services extend to raw material sourcing, product development, finished goods assembly, and drop shipping, supported by quality assurance and testing capabilities. Green Mountain Knitting serves the industrial wear, first aid and PPE, sportswear, and fabric markets. Its customer base includes distributors and businesses requiring customized industrial safety products and apparel, with regulatory compliance managed by an in-house team. The division was created to address the U.S. market directly. The company emphasizes constant innovation, ongoing research and development, high-quality products, and competitive pricing as drivers of its growth. Vertical integration, near-shore and off-shore manufacturing flexibility, and the ability to accommodate a wide range of design elements are cited as key differentiators.
