Chonos Ultra Down Jacket
Product Information


Built for high altitude and extreme cold conditions, the Chonos Ultra Down Jacket combines high quality goose down and a unique PERTEX® Quantum Y Yarn outer shell fabric to create a supremely warm, lightweight and packable weather resistant boxwall jacket. The Chonos Ultra Down Jacket has minimalist weight saving features including a tailored ‘active mountain’ fit that prevents the hem raising whilst reaching high, a fully adjustable helmet compatible hood that can be easily stowed away, two deep A-line hand-warmer pockets and its own waterproof dry bag.


  • Constructed from PERTEX® Quantum Y Yarn which provides increased downproofness and a strong tear strength

  • PERTEX® Quantum Rip-stop lining throughout ensures the jacket is incredibly lightweight
  • Technical tailoring to prevent arm lift raising the lower hem whilst reaching high
