The quickest way to check is to see if your monitor pouch (located toward the apex of your SlumberPod) has a zipper or not. The 3.0 version does not have a zipper to make it even easier (and quieter!) to reposition your monitor. Other features on the 3.0, include a mesh pouch that can be used for a fan or monitor toward the top of the SlumberPod and an additional ventilation panel on the back of the SlumberPod.
