GORE® TENARA® Sewing Thread can improve the performance of outdoor and marine products that demand exceptional seam life and seam integrity. Conventional seam threads can embrittle or break after a few years of exposure to the elements. Only GORE TENARA Sewing Thread durably withstands exposure to sunlight, saltwater, harsh chemicals, pollution and extreme temperatures without fading or deteriorating. 

That’s because GORE TENARA thread has a unique ePTFE fiber construction that extends the life of fabric seams — and ultimately, the life of the products in which they are used. Due to its exceptional material properties and use of non-fading pigments rather than dyes, colorfast GORE TENARA Sewing Thread retains its bold appearance over time, even after exposure to harsh cleaning chemicals.

And because this durable thread does not deteriorate — not even after prolonged exposure to UV radiation — it is guaranteed to outlast the fabric in which it is used. 

Guaranteed to last

  • Unaffected by sunlight

GORE TENARA Sewing Thread maintains its strength even after regular exposure to sunlight’s UV rays. This thread effectively resists breakage because UV resistance is permanently built right into our fibers — it’s not a coating or additive that can wear off.

  • Weather-proof

GORE TENARA Sewing Thread remains flexible and strong in extremes of hot and cold. It won’t absorb water and it durably resists acid rain, saltwater, pollution, snow and freezing temperatures.

Beauty that endures

  • Easy to clean

GORE TENARA Sewing Thread is unaffected by acids, alkaline solutions, bleach and cleaning chemicals. Just as important: it will not stain.

As shown, after a red-wine spill, a typical polyester thread absorbed a red stain that couldn’t be removed by cleaning. Compare that to the GORE TENARA Sewing Thread, which cleaned up easily and looks like new.

  • Colors will not fade

GORE TENARA Sewing Thread is pigmented — not dyed. Because these non-fading pigments are highly resistant to light, our colorfast threads retain their bold appearance over time. In tests conducted by an independent laboratory*, GORE TENARA Sewing Thread received the highest score possible: a light-fastness rating of 8.

* Tests conducted by Q-Lab Corporation in 2019 according to DIN EN ISO 105-B06A:2004-07.
