Long Down Jacket

Recommendations for buyers

• ✓
  Insulation Ratio

  Aim for a minimum of 80% down filling for optimal warmth. Higher percentages of down versus feathers provide better heat retention with less weight.
• ✓
  Shell Functionality

  Ensure the outer fabric has a DWR (Durable Water Repellent) coating. This prevents the down from getting wet, which would otherwise cause it to lose its insulating properties.
• ✓
  Length and Coverage

  For maximum protection in sub-zero temperatures, choose a jacket that ends between the mid-thigh and the knee to protect the femoral arteries from wind chill.
• ✓
  Closure Systems

  Look for dual-direction zippers which allow you to unzip from the bottom for better mobility while sitting or walking, paired with a buttoned storm flap.
