Symmetrical Profile

The symmetrical profile has increased thickness distally to provide increased comfort and protection. This tapers to 2.5mm proximally for easy donning, and a thinner edge when cutting. Being uniform circumferentially means that it can be rotated by the user to increase its lifespan.

  • 9mm distal end
  • Thins to 2.5mm proximally
  • Uniform circumferentially

Select Fabric

The Select fabric is WillowWood’s most durable and comfortable offering. Through the utilisation of unidirectional stretch material, pistoning is eliminated without the need for a distal matrix. This also means that it is easier to don for the user, and can accommodate more volume fluctuations, without the need for a new liner.

Features and benefits

  • Unidirectional stretch – eliminates pistoning without a distal matrix
  • Increased durability
  • Easy to don
  • Can accommodate volume fluctuations

Accordion Umbrella

The accordion umbrella increases socket comfort by conforming to the shape of the underlying residuum, reducing stress and providing a more uniform pressure distribution. The umbrella size correlates to the liner size, meaning equal comfort and conformity across all sizes.
