"Wellness Brief Superio Series, Medium 24"" - 36"". Superio is our top of the line brief providing unprecedented protection. They feature a super strong plastic back, a wider core, and a white outer shell. These briefs are so innovative that they were featured on Discovery Channel's How stuff works and are designed to last 8-12 hours using NASA inspired multi layered InconTek technology similar to designs used by astronauts in space for long missions. It has a unique scheduled changing system and is therefore is one of the easiest to use. This is revolutionary because changes can actually be scheduled to only once in eight hours/ three in 24 hours putting the wearer or caregiver in control with no worry of any exposure to the effects of urine. More cost effective than other briefs because of fewer changes and rarely requires expensive creams or ointments."
