The Grepp tape is based on a synthetically produced, plant based fiber called TENCEL™ which comes from trees. The wood pulp is made into a base from which the fibers are then woven into threads. This is what faces your hands with the Grepp tape.
I liked the overall feel and tacky grip, (when it was dry), of this tape. It does damp out some vibration – not all of them – so you end up with a nicer experience in regard to hand comfort. I liked how the cross-section allowed for the tape to have that soft-ribbed grip which aids in situations that might be a bit rowdier than your typical road surface.
The tape was nice and kind of rubbery feeling when pulled from the box. It also had a slightly tacky feel as well. The installation was simple and by not stretching the tape, it left it pretty soft feeling when installed.
