Alpha® SmartTemp Gel Progressive Liner

A premium thermoplastic elastomer (TPE) gel that is combined with the heat management properties of a phase change material (PCM). This heat absorption technology allows the liner to absorb and store heat from a residual limb, and delay the onset of sweat. The liner releases the stored heat as the body cools down, stabilising the skin temperature.

This proprietary blend of TPE gel and heat absorption technology provides the most comfortable and protective liner yet.

Features and benefits

  • The only gel liner with heat management technology
  • Reduced sweating
    • Can help reduce tissue breakdown
    • Can improve suspension

Progressive Profile

The progressive profile provides the ideal combination of thick gel for sensitive areas, and thin gel for movement and donning.

  • 9mm thick distal end
  • 6mm along tibial crest
  • 2.5mm posterior to knee
  • 2.5mm circumferentially at proximal end

Select Fabric with panel

The Select fabric is WillowWood’s most durable and comfortable offering. By combining two distinct materials, it offers support, compression and flexibility. To prevent pistoning, the majority of the fabric has unidirectional stretch, meaning a distal matrix is not required. This allows easy donning and accommodation of volume changes without the need for a new liner. To reduce shear stress over the patella, there is a multidirectional stretch panel over the knee which improves comfort in flexion.

Features and benefits

  • Unidirectional stretch – eliminates pistoning without a distal matrix
  • Multidirectional stretch – reduces shear over patella
  • Increased durability
  • 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 corelates to the liner size, meaning equal comfort and conformity across all sizes.
