ThermaTek™ Insulation

Arc'teryx ThermaTek™ Insulation

Exclusive to Arc'teryx, ThermaTek™ is a continuous filament, synthetic insulation that is treated with DWR (Durable Water Repellent) to make it highly hydrophobic, which means that it repels moisture very efficiently. The lofty insulation is then laminated to a backing fabric to ensure an even distribution and insulation.

Key Advantages

  • Arc'teryx's most efficient insulation when used in humid and wet conditions
  • Very resilient and durable
  • The fastest drying fill insulation in our collection
