I would agree that it's tight for 4. Great tent for 2 adults and 2 kids...but 4 adults with gear would really be pushing it IMO. I love mine though. Very versatile with the floor/net/tent modularity. I also just picked up a MLD 2 person innernet to save weight over the SL nest for when it's just me and my wife. And hoping to add a stove jack and ti stove sometime soon if funds and time allow.
