Tenacious Tape
Also: Gear Aid Tenacious Tape
Tenacious Tape is a self-adhesive repair tape from Gear Aid. It holds very well on uncoated nylon, less so on the smooth TPU outer side.
Luc Mehl writes it works best on uncoated nylon (the inside of some tubes) and isn't ideal for the TPU outer side. He therefore uses it as a backing from inside. Alpacka recommends it for holes under about 1 cm and pinholes in seats.
