difference between activa mask cushions

After years and years of wearing a Mirage Activa mask, I've wondered if there is a difference between the "medium" and "standard" cushion, and I think there is. Anybody want to trade a medium for a standard?

Nobody else wearing Activa?

You may want to see if you can change the topic from "There is a difference" to something like "Activia Mask Users". That way people who wear it would know they may want to look at it. Right now, it's merely random chance that someone reads this topic.

thanks, I'll do that.

I've been using a Mirage Activa mask for 12 years now, and all I've ever used was the size "Standard".

I can't answer your specific question, but it seems like the Standard size would be the same as a medium.

Hopefully someone will haved a definitive answer.

actually, I think I've figured out the medium is a LT size, and the standard is the plain vanilla size. I have bought some of each thinking the same as you, but the other night I switched from the standard to the medium and it felt better, so I would like to trade my standards for mediums.
