The Outdoor Vitals Oblivion is an insulated inflatable sleeping pad with an R-value of 3.5 per the standardized ASTM F3340 test, putting it at the upper edge of 3-season use — comfortable through spring, summer, and fall, but you'd want to add ground insulation for snow or freezing nights. Insulation comes from a reflective foil layer rather than foam, so it's a pure air construction that packs down small when deflated.
I-beam baffle construction holds its shape better than simple tube baffles and limits air shifting when you move around, which side sleepers in particular will notice. At 7.6 cm thick, it puts decent distance between you and the ground, and both the top and bottom fabrics are 20D ripstop polyester — tougher than ultra-thin 15D options while still staying in ultralight territory. Two valves allow separate inflation and deflation without air mixing between them.
The regular size (183 × 53 cm) weighs 632 g and ships with a pump sack, so there's no need to inflate by mouth and risk introducing moisture that degrades the foil's insulating performance over time.
