@Laurieo63 Thanks for reaching out Laurie!
While we don't have the items you are looking at in front of us to test them out, it appears as though the Big Agnes Deer Park sleeping bag should be able to fit your Exped sleeping pad, as the sleeve is pretty stretchy. It will be a snug fit for sure, but it should work.
One other consideration would be to look at the Big Agnes line up of new sleeping bags. It looks like they redesigned the sleeve component of their bags to allow more versatility in sleeping pads. In fact, the landing page of their website has a sleeping bag with multiple pads under it!
Hope this helps, thanks!
