Picked up a brand new Exped SL 7. It held air for about 6 hours. Thought maybe first use, cool night, maybe it just lost a little air. Crawled out of my bag and blew it up, flat again in 15 mins. Will be returning to REI for a replacement tomorrow. This was in a clean tent with ground cloth. Just seeing if others have had good durability with them. Plan is to give them another try instead of returning and switching brand.
