TEMPERATURE INDEX

At Pyrenex, thermal insulation is a priority. Thanks to a unique know-how in the making of one of the world’s best natural down, our down jackets, parkas and vests offer a natural filling with an exceptional filling power allowing to protect your body from very low temperatures in winter or during mid-season.

Each jacket is recommended for a specific temperature range. These temperature ranges are provided only for guidance. In extremely cold conditions (under 0°C or 32° F), we advise you not to stay still and to keep a light activity, even while wearing your natural down filled Pyrenex puffer jacket. We also advise our customers to enquire about local weather conditions and follow any advice given.

  • Mild : lightweight insulation for temperatures above 5°C or slightly lower during active situations
  • Cool : versatile insulation, keeping you warm during most situations
  • Cold : excellent thermal insulation, designed for optimal warmth in winter
  • Heavy cold : extreme insulation, for heavy cold conditions
