I have never ever had a problem with pop off myself, but I would imagine it would help. The addition of the sleeve for me does two things; it provides a nice tight feeling but most of important of all it improves the air seal which will of course also makes the liner grip more. These sleeves are not expensive either and as you can get 3 or 4 “mouths” out of them it lasts ages.
