In the quest to reduce the weight of my “Big Three” my sleeping mat offers the second biggest chance to save weight. My current mat is a Thermarest Prolite (woman’s). I bought the woman’s version, because for the same advertised weight, it has an R-Value of 2.8 rather than the 2.2 of the men’s, it may be 6 inches shorter but that suites me fine.
To justify the cost of changing my mat, I need to save at least 150g. I’ve looked at quite a few mats and finally chosen the Thermarest NeoAir. The advertised weight for the small version is 260g which is 188g lighter than my Prolite, and if it suites Chris Townsend and Jorgan Johansson then it must be ok!
