Gütermann TERA 80 is a continuous-filament polyester thread built for technical sewing, the kind of thread you want holding outdoor gear together. The continuous-filament construction gives it high breaking strength and a smooth, even surface that feeds cleanly and resists abrasion, so seams stay strong through hard use and weather. It's a go-to for small packs, lightweight bags, pouches, and gear repairs, anywhere you want a strong, reliable seam without bulk. It sews smoothly, handles tension well, and has a heat-resistant finish that holds up to fast machine sewing. Each cone holds 800 metres, enough to carry you through plenty of projects. Match it with the right fabric for your build, or browse more thread for other weights and colours.
