Features

  • Nutria fur has a distinctive appearance, with a lustrous and coarse outer layer and a dense, insulating underlayer.
  • The outer coat of the nutria, whether yellow or brown, appears rough and unattractive, concealing a luxurious undercoat known as nutria fur, highly sought after for its use in clothing. 
  • The outer guard hairs of the fur have a coarse texture that helps repel water, making it suitable for use in damp or rainy conditions.
  • Nutria fur is soft to the touch, providing a luxurious feel. 
  • Despite its softness, the fur is also durable, making it suitable for various products requiring both comfort and longevity.
