Why do GORE-TEX® garments need seam tape?
The holes made by needles in seams may be small, but they can cause leaks. That’s why even the most waterproof, breathable, windproof fabric won’t keep you dry and comfortable if the seams are not completely sealed.

For absolute weatherproofness, GORE-TEX® garments rely on the Micro GORE-SEAM® tape technology. Seam tape is used to completely seal every tiny hole created by sewing machine needles when GORE-TEX® fabric is made into garments.

No other fabric manufacturer goes to such lengths to ensure total weather protection. In addition to manufacturing our own GORE-SEAM® Tape, only Gore consistently tests finished garments to ensure they pass our meticulous quality and performance standards.
