I'm not entirely sure what material the Night Vision jacket's made of but you can get Goretex repair patches for appropriate repairs on non-coated waterproof materials.
Alternatively, there's heat-activated seam sealing tape which is my preferred repair material for many synthetic shells. The problem is that if you don't do it right you melt a hole in your jacket instead of repairing the tear. If you want to go this route PM me and I'll send you a length of tape (I've got miles of it) and instructions.
