What length should my inflatable mattress be for backpacking?

Question

How many inches long should it be if I'm 69 inches tall?

Answer 1

depends if you want your feet on the matress or not....

Answer 2

you're tall enough to use the full length pad

during summer you can use the 3/4 length to save weight or if you tend to sleep with your legs drawn up

A good friend is a little shorter than you and uses a 3/4 pad and puts his pack at the bottom to keep his feet off the ground

he has bad circulation in one leg and elevating his feet helps keep them warm
