Waterproof breathable membrane - RespiGard

RespiGard™ by Celgard is a unique membrane designed for outdoor apparel. Its innovative pore structure is too small for water droplets to penetrate but features high porosity that allows for airflow and moisture evaporation.

Outdoor sportswear and coats made with our RespiGard™ membrane have won numerous awards, including the 2021 Performance Days Performance Award and the 2019 and 2020 Outdoor Retailer’s Innovation Awards.


Our proprietary and patented products and manufacturing process provide a membrane that:

  • Is naturally hydrophobic (repels water)
  • Has smooth and uniform pores too small for water droplets to penetrate
  • Features high porosity that allows for airflow and moisture evaporation


RespiGard™ membranes are naturally lightweight due to their high porosity. Their material properties also result in a quiet product that is very soft and comfortable to the touch.


RespiGard™ membranes are produced using a solvent-free manufacturing process with a low carbon footprint. The polypropylene-based material is recyclable and completely perfluorocarbon (PFC) free.
