Hole in Quilt Snap-T, how should I sew it?

I have a small hole in the sleeve of my quilt snap pullover. I can’t justify sending it in with such a small tear but it is also losing insulation. The material seems a bit more fragile (for lack of better words) so I was wondering if there is a suggested sewing pattern to follow. Thank you!
