P.U.R.E. is a new insulation-manufacturing technology that removes the need for heat to melt bonding fibers.
Typically, insulation manufacturing requires heat to melt the bonding fibers that provide structural integrity for the insulation. Materials like polyester, wool and down can be used for insulation. Unlike wool or down, however, polyester can be altered at the chemical level to achieve various structures depending on what the insulation is intended to do.
PrimaLoft® P.U.R.E.™ (Produced Using Reduced Emissions) technology reduces energy use and carbon emissions during the insulation-manufacturing process by eliminating the need to melt the polyester fibers and thus removing heat from the process.
Turn Down the Heat
Where We Are
To cut carbon emissions from the manufacturing process for our Nano Puff® collection 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).
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 in our material-manufacturing processes, Patagonia continues to integrate innovations like P.U.R.E. that reduce energy use and CO2 emissions.
