MH 300D/3 High Tenacity Filament Polyester Sewing Thread is a three-ply industrial sewing thread spun from 100% continuous polyester filament for heavy-duty, load-bearing seams.

The 300D/3 build sits at the heavier end of the high-tenacity filament range, giving each stitch the tensile strength and abrasion resistance needed to hold seams in canvas, tarpaulin, webbing, bags, and heavy leatherwork.
