Extra strap really helps with Swift nasal pillow

My original swift nasal pillow seemed pretty unstable for a long time. I finally put a 1 and 1/2"wide strip of elastic on it and it has totally stabilized it.
I took the piece of elastic and wrapped it around the lowest part of the headgear (right after the dip in the headgear by the pillow) on each side and pinned it to itself. Its like a second, lower strap on the headgear. it works perfectly.
