Steph, i use them with all my WN pockets, both OS and high and standard SS. They completely fill the standards so are a little shorter in the highrise ones. From what i remember of the OS on the large setting they had a little space but it never caused a problem. We do have GK anytimes which obviously they're perfect for and then BG's which i have to confess to not having touched since Poppy was tiny (they're still on the small setting with only newborn inserts in) because i'm not a fan but i imgaine they'd fit in those the same as WN..
I just like that they'e Mike proof, he can't go wrong because he doesn't have to worry about any folds.
