AliMed® T-Gel™ Cushion T-Gel™ elastomeric gel has the consistency of fatty tissue. It can "slide" and move laterally, so it is effective in reducing shear forces. Unconditionally guaranteed not to leak or dry out if accidentally punctured or cut. Do not confuse T-Gel with air or liquid systems that leak and require constant maintenance. Cut T-Gel without harming the material. Includes black knit , or ripstop nylon cover.
