This is a lightweight air mattress from the Therm-a-Rest NeoAir series. The actual weight is 196g, with a length of approximately 113cm, a maximum width of approximately 49cm, and a thickness of approximately 6-7cm. A stuff sack is not included, so please prepare your own. It has been used only 2-3 times since it was purchased new. Upon listing, I re-inflated it by mouth to confirm that it holds air and is in good working order. I have disinfected it with alcohol, but if you are concerned about hygiene, please re-treat it yourself. There are no air leaks, and there are no issues with use. This is ideal equipment for those with an UL (ultralight) mindset. It is offered at a low price to those who value the equipment and understand its worth, for those who prioritize weight reduction and want to travel or hike with the minimum necessary gear. Please refrain from price negotiations.
