Long lasting .040″ thick hydrogel. Superior conformability to body contours. Quick, moderately aggressive tac. Firm, yet gentle electrode to skin contact for multiple applications. High re-wettability/dry out resistance. Effective in high heat and humidity. Highly conductive carbon film for even current distribution. Soft foam covers. Flexible and conformable to a variety of application sites. Soft molded socket connector provides superior connection to the lead wire. Highly conductive pigtail wire strands are flexible and durable for multiple uses. A tinted double-coated storage liner simplifies removal and storage. Both sides are also gel friendly, so electrodes can be stored on either side.
