Seam sealing & waterproofing

Every stitched seam is a hole in a waterproof shell. Taping closes them, panel by panel, so the garment performs as one surface.

How it works

Every stitched seam in a waterproof shell is a line of needle holes. Seam sealing closes them with heat-activated tape applied to the inside of the seam, so the garment performs as one continuous surface rather than a set of panels.

  1. Seam is sewn

    The panel seam is sewn and pressed flat so the tape has an even bed to sit on.

  2. Tape is applied

    Heat-activated tape is run along the seam under controlled heat and pressure.

  3. Detail areas are taped

    Zipper ends, hood channels and pocket openings are taped separately, with dots where seams cross.

  4. Checked before wash

    Sealed garments are checked before wash to confirm the tape has bonded across its full width.

Applications

  • Waterproof shells and hardshells
  • Ski and snowboard jackets and bibs
  • Rain jackets, parkas and coveralls
  • Hunting and motorcycle outerwear

Advantages

  • Closes needle holes across the whole garment
  • Taped zipper ends and hood channels, not just body seams
  • Consistent application on dedicated equipment
  • Checked before wash as part of in-line QC
