The Underlay is a prosthetic accessory designed to help lower-limb amputees manage sweat, heat, humidity, and odor inside their socket.

• Worn directly against the skin, underneath the user’s liner
• Breathable knit engineered to draw sweat away from the skin up to the mesh area for all-day comfort
• Two advanced Polygiene technologies: StayFresh® & StayCool®
• The breathable mesh allows humidity to evaporate more easily
• Prevents the growth of odor-causing bacteria, keeping your product fresh even in sweat and humidity
• Lower fabric temperature for a refreshing feel. Activates with sweat to keep you cool when it matters most

Problems addressed:

• Intense heat felt inside the socket increasing discomfort
• Sweat & hyperhidrosis impacting traction and comfort
• Humidity inside the socket increasing skin problems & odo

Type of patients:
The Underlay TT & TF are intentionally designed to be highly versatile and compatible with the vast majority of prosthetic configurations used in clinical practice

It’s particularly effective for:

• Patients who sweat heavily or experience hyperhidrosis
• Individuals who frequently remove their prosthesis to dry their limb
• Active users who overheat easily
• Patients prone to skin breakdown, maceration, or odor
• Patients using suspension systems where moisture can compromise adherence

Polygiene technologies:

• StayFresh® antimicrobial coating, which inhibits
  odor-causing bacteria and keeps the product fresher for
  longer.
• StayCool® thermo-reactive polymer matrix, which is
  activated by moisture to lower fabric temperature by 2–3°C
  (4.3–5.4°F), helping prevent overheating inside the socket

Configurations

• Open : Allows the Underlay to be placed higher on the
  residual limb and exceed the length of the liner. This is
  our recommended design because it is more efficient
  for humidity & sweat evaporation
• Closed : If you prefer a more traditional configuration

Study (n=15):
Feedback was collected from lower-limb amputees.
Participants tested the Underlay during daily wear and physical
activities for several weeks.

51% Reduction in humidity inside the liner
34% Reduction in perceived heat while using the Underlay.

How to use:

2. Roll your prosthetic liner as usual above the Underlay ensuring the Underlay extends above the liner
