Alpha® Hybrid AK Symmetrical Liner

A reinforced blend of durable thermoplastic elastomer (TPE) gel containing mineral oil and vitamin E. Designed to combine the comfort of Classic Gel with the durability of silicone, this all-round liner is as the name suggests – the best of both. With sufficient flow for bony prominences and suitable stability to control loose tissue, the added durability, compared to Classic gel, means higher activity users can achieve a comfortable fit with less regular liner replacements.

Features and benefits

  • Balanced flow and rebound provide a great solution that can minimise peak pressures whilst providing stability and durability.
  • The right amount of stability to cater to a wide range of tissue consistencies
  • Suitable for all activity levels, from low to high
  • Unidirectional stretch – eliminates pistoning without a distal matrix
  • Increased durability
  • Easy to don
  • Can accommodate volume fluctuations

Measuring Guide

Ensure accurate measurements at 4cm and 30cm from the distal end to determine the most appropriate liner for the user.

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

Select-tyget är WillowWoods mest hållbara och bekväma erbjudande. 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.

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.
