Primaloft Gold

PrimaLoft Gold Insulation

PrimaLoft synthetic insulation materials and performance yarns focus on four main characteristics:

  • Warmer
  • Drier
  • Softer
  • More compressible

Synthetic insulation materials are tried and tested, providing reliable warmth, even when wet. Proven in the unpredictable U.K. weather, Montane and PrimaLoft work together to produce iconic clothing and equipment.  

Montane also uses PrimaLoft’s performance yarn in its Primino® range to create supremely comfortable and ultra fast drying baselayers.
