What is Seam Tape? Heat-bonded tape applied over stitched seams on waterproof garments to prevent leakage.
Seam tape is a thin polymer tape that seals the needle holes left by stitching. Without seam tape, a waterproof membrane leaks at every needle puncture. Quality rain jackets and tents have fully taped seams; cheaper rain jackets often skip taping or tape only the most exposed seams. Look for fully taped or fully seam-sealed in product descriptions.
