This style of trim has become one of our most popular options for piping elite level football, basketball and baseball uniforms. The W-HV Series of warp knit trims offers better opaqueness and stability than the standard weight, W Series. Comprised of stretch nylon colors, our warp knit trims have exceptional color fastness and a soft hand. Warp knit trims have larger minimums than our other styles of knit braid, so they are typically used for larger projects.
