Weight characteristics
Varies by face fabric and construction rather than by membrane alone.
Durability characteristics
Durability depends on the textile, laminate, seams, use and care; denier alone does not establish abrasion resistance.
DWR requirements
Face fabrics carry a durable water repellent finish. Repellency wears off with use and needs reproofing; the membrane itself is unaffected.
PFAS / PFC information
Check the current season's material declaration. Many brands have moved to PFAS-free repellent finishes, and platforms differ by year and by garment.

Care instructions

  • Follow the garment label and official care instructions. Use the specified cleaner; Gore permits a small amount of suitable liquid detergent for conventional GORE-TEX outerwear. Avoid products those instructions prohibit.
  • For DWR-finished garments, clean first and reproof only if needed, following garment and treatment instructions. Do not apply DWR to persistent-beading constructions such as SHAKEDRY.
  • Tumble dry warm or press with a cool iron under a cloth if the care label allows, to reactivate the finish.
