Perfect for Back/Side Sleepers
As a back/side restless sleeper, it stays secure with no leaks even if a pillow pushes it gently from the side. The mask portion is entirely silicone and very comfortable. A++ product, but I received a M mask instead of the L that I ordered.

Excelente actualización
De las mejores mascaras para CPAP que he usado, muy ligera, suave y cómoda (vs F30i), no se siente el flujo de aire en frente de la cara. Le pongo 4 estrellas ya que a pesar de ser un producto original de ResMed, tamaño correcto de la mascara, el soporte de la cabeza viene de tamaño grande, muy grande, que al principio puedes ajustar al limite, pero creo que con el uso y lavadas, seguramente cederá y al corto plazo va a ser necesario reemplazarlo.

Perfect fit
I absolutely love the F40 mask. I have a very small head so I've had a hard time finding a mask that feels good, fits well and provides a good seal. The F40 small wide does all of that. I highly recommend the F40 for those that need other sizes as well. Its the most comfortable cpap mask I've ever used.

Terrific product
Why did you pick this product vs others?: After using a full mask for two years, this is the best product ever. It allows for you to breathe through your nose and your mouth or mouth closed depending on how you sleep. Great fit very comfortable. I like that it allows for open mouth sleeping and breathing.

has potential
it was mokay the 1st night but the 2nd night it started leaking a bunch and there was nothing i can do to make it not blow air. I has to go back to my f20 airtouch , came with a strap though but and it had potential since i can wear my glasses it might work for someone else
