Insulation, Care & Service

Kanuk coats are engineered to protect against extreme temperatures, with comfort ratings ranging from 0°C to -35°C.

Our collections are categorized into four comfort zones:

• 0°C to -10°C
• -10°C to -20°C
• -20°C to -25°C
• -25°C to -35°C

These ranges are provided as general guidelines. Individual cold tolerance can vary based on external factors like wind and humidity, as well as internal factors such as physical activity, fatigue, and overall health. For this reason, the effective comfort zone may shift by approximately ±5°C in either direction.

Down is the soft, lightweight layer found beneath the outer feathers of a water bird. Its exceptional insulating power comes from its natural structure: each cluster contains thousands of fine filaments that interlock to trap air, forming a thermal barrier that retains body heat while remaining breathable. This composition delivers warm insulation with minimal weight.

Kanuk uses a premium 90% duck down / 10% feather blend, offering high-performance insulation that combines loft, comfort, and durability.

Certified by the Responsible Down Standard (RDS), our down
is ethically sourced, ensuring the humane treatment of animals and full
traceability from farm to finished garment.

Thindown® is a patented insulation fabric made from real down feathers, engineered to provide warmth in a thin, lightweight format. By blending natural down with synthetic fibers and compressing them into a uniform sheet, Thindown® creates a versatile material that can be cut and sewn like traditional fabric. This technology provides warm insulation without bulk.

Synthetic insulation, such as PrimaLoft®, is engineered to replicate the insulating properties of natural down. Made of ultra-fine polyester fibers, it retains heat & dries quickly. Lightweight and breathable, it offers reliable warmth even when wet.

How to care for your winter coat, shell, or raincoat with synthetic or Thindown® insulation—without damaging it:

• Machine wash in cold water using a front-loading washer.*
• Use a mild, bleach-free detergent.
• Remove any detachable fur or visors before washing (if applicable).
• Close all zippers and detach the hood from the collar (if applicable).
• Tumble dry at low heat for synthetic insulation. For coats with Thindown®, tumble dry at medium heat.

Important care notes:

Do not dry clean. Do not wash the fur. Do not use bleach or detergents containing bleach or stain removers. Do not iron. Do not use fabric softeners. Do not tumble dry at high temperatures, this can damage the insulation and reduce its performance. Always ensure your coat is completely dry before storing.

*Note: Always use a front-loading machine. Top-loading washers are less effective as Kanuk coats repel water and tend to float, leading to poor washing and rinsing results.

Down insulation can be machine washed or dry cleaned, but
it’s essential that the coat is thoroughly clean after the process. If down
clusters are clogged with dirt or dry-cleaning solvents, their insulating loft
will diminish.

• Wash in cold water using a front-loading washing machine.*
• Use a bleach-free detergent specifically formulated for down.
• Remove any detachable fur or visor before washing (if applicable).
• Always close all zippers and remove the hood from the collar (if applicable).
• Tumble dry on medium heat with clean drying balls to prevent clumping. This may require several drying cycles. Check between cycles and gently break up any lumps by hand. Ensure the coat is completely dry before removing it from the dryer.

Important care notes:

Do not wash the fur or visor. Do not bleach or use detergents containing bleach. Do not iron or use fabric softeners. If the coat doesn’t fully regain its loft after washing and drying, repeat the process—clean, dry down always recovers its natural puffiness. Some fabric protectors or stain removers can stain your coat; always test on a hidden area first.

*Note: Always use a front-loading machine. Top-loading washers are less effective as Kanuk coats repel water and tend to float, leading to poor washing and rinsing results.
