My sleeping kit weighs in at 1568g; I use a Mountain Equipment Xero 550 sleeping bag, with a Jag Bag silk liner to keep the inside clean. My current mat is a Thermarest Prolite (Woman’s). The Xero 550 is packed in a 15 litre Pod lite event dry bag, and the Thermarest travels in its original stuff bag with the label removed.
As I have a tendency to sleep fairly cold, I’m reluctant to make a costly down grade to my sleeping bag, only to find it’s not warm enough, so no changes here for the moment.
With the advance in sleeping mats over recent years, I could save some weight by replacing the Thermarest Prolite, particularly if I can get my head around using a shorter mat.
