This repair tape has an adhesive on one side so that it will easily stick to the inside of our Ultra packs. These will stick to the inside of either the Ultralight or the Rugged pack swithout any additional adhesive. You will need some additional adhesive such as Seam Grip or Aquaseal when using these on the outside of the pack, or when using them on our standard EPX200 fabric. 
 
The adhesive backing makes it easy to repair a pack while on trail. Just peel the tape and stick it to the inside of the damaged area.
