This is a Therm-a-Rest NeoAir XTherm air mattress. I purchased it new and only inflated it once at home using an electric air pump. I am selling it because I haven't had a chance to use it. Everything in the photos is included. With an R-value of 6.9, this is a very warm mattress. It's also very comfortable due to its thickness. It's lightweight for a high-performance air mattress, weighing only 430g.
