@dregan713 My guess...Only good for summer use as only has R value of 1.8. 2 inches thickness is a bit thinner than some other inflatable pads. Probably border line or not thick enough if you are an active or side sleeper. At 21 oz it is not the lightest but quite light. Packs up quite small at 4.5X9 inches. Including the battery powered pump makes it a good value although I would not bring that backpacking personally (extra weight). 20 inches wide is only just wide enough which is bearable for lightweight backpacking and necessary for some 2P tents but for other uses 25 inches is much nicer. Therm-a-rest quality is generally high.
