a tale of two nights, two masks

[eok361]

i'll have to make two posts to show the results from these two masks on two different nights.

first off: i sleep the same every night...on my back, due to back and shoulder issues. 

this night was with an n20 mask, releaf scc, and kinetic tape. 

the awake period was to tend to the older pooch who needed some attention.

this is the second night.

this time it was with a F&P evora. same scc and no tape.

i'd like to use this mask regularly, but end yp having night's like this with it. the taping is an annoyance, but i guess it is what it is.

i'm just curious why this mask would create these problems.

both nights are with the same machine, with the same settings. 

thanks
