In that second picture, the 7 footer looks pretty close to the ends. So if they were on a 2.5″ thick pad and in a sleeping bag/quilt, it appears they’d be touching the ends, as others have commented. Even without a sleeping bag, that’s awfully close to touching the fly considering it’s a single wall where you want to be safe distance away since it may be wet.
The length specs are 88″ and a 7 footer is 84″, so that’s a theoretical 2″ of gap at either end for the sleeping bag. I don’t see how 2″ minus the thickness of a sleeping bag = safe distance to the fly. Perhaps I’m misjudging this.
The closest competition here is the Plexamid, which has the same height (48″) and is slightly longer (89″ vs 88″). The Aeon looks to have more sleeping bag clearance because there is a pitch lock corner at one of the two end corners, but since the other end corner still slopes to the ground, I don’t see a major advantage. Either way, 95+% of hikers will fit.
I say this because I’m genuinely unclear why this is one of the points being emphasized. I agree the Aeon does have major advantages over the Plexamid, but I think the more impressive ones are the simpler pitch (fewer stakes), mesh door that doesn’t fall in the dirt, stormworthyness, better floor tensioning, and increased volume from the Pitch Lock corners.
