Edgup is a unique idea! And the thoughtful implementation of it was created by Jason Eisner. Sometimes in life we find ourselves having a practical problem and then wishing we had a practical solution. For Jason, it was that he wanted to have a well kept hair line, but was unable to see the back of his neck. A common problem for many, and he found a great solution. The Edgup is made with a 100% grade A Silicone material that is perfectly flexible and holds the hair above the neckline, just out of the way, so you can clean up that neck without anyone's assistance. You will be able to look like you've been to the barber shop while saving the time and money for just that little bit of clean up that makes all the difference.
