DO NOT BUY
"DO NOT BUY! Worked once then developed slow leak that would leave me fat on ground after 3 hrs. Resulted in terrible sleep. No puncture but seam weld failure around valve. Trying to fix leak was huge exercise, and no glue provided with patches so took several attempts. Meanwhile, 30 year old Thermarest keeps on keeping in, but is shorter and thinner. Very disappointed with this Kathmandu product, put me off Kathmandu altogether."
