P.U.R.E. is a new insulation-manufacturing technology that removes the need for heat to melt bonding fibers.
Polyester is a polymer made from carbon molecules that can be manipulated in various ways depending on the intended use. Polyester can be made from sugar or petroleum. It can be recycled if the waste stream that it’s coming from is homogenous and free of impurities like food scraps or dirt. It can be used to create insulation for clothing or buildings. Unlike down or wool, polyester can be altered at the chemical level to achieve various structures depending on what the insulation is intended to do.
Typically, insulation manufacturing requires heat to melt bonding fibers, which provide structural integrity for the insulation. PrimaLoft® P.U.R.E.™ (for Produced Using Reduced Emissions) reduces energy use and resulting carbon emissions during the insulation-manufacturing process by reducing the need to melt the fibers and thus removing heat from the process.
Turn Down the Heat
Where We Are
To cut carbon emissions out of the new Nano Puff® collection manufacturing process without altering a single thing about how the garments perform, we partnered with PrimaLoft to develop insulation that self-bonds and self-cures through exposure to air instead of being baked in ovens (one of the traditional methods for holding strands of polyester insulation together).
This P.U.R.E. technology reduced the footprint of the insulation in our Nano Puff styles by more than half compared to using 100% virgin polyester and traditional production methods.
Across our product line, Patagonia continues to integrate material manufacturing-process innovations such as P.U.R.E., which reduce energy use and CO2 emissions.
