Rochester Medical Spirit™ Style 3 Hydrocolloid Sheath Male External Catheter Medium 29mm, Silicone, Latex-Free Combines adhesive and moisture-wicking properties of hydrocolloid with the breathability and flexibility of silicone. The Rochester Spirit™ Style 3 external catheter is the same as the WideBand® external catheter but provides 70% more adhesive area than traditional self-adhering designs. Combined with patented forward placement of the adhesive, this design helps prevent accidental catheter detachment.
