The Trekker II Mat is based on the original Trekker Mat but with 2 valves for quicker inflation & deflation and double the thickness. Some end users have been requesting a thicker mat for some time now for greater comfort as well as enhanced insulation properties. With its 2 inch thick foam core the Trekker II mat achieves this. It rolls to similar size and diameter of the traditional green military foam mat, but with much more comfort while at the same time creating a nice insulating barrier between the user and the cold ground.Length: 74 in.Width: 22 in.Thickness: 2 in.Weight: 52 oz.Temperature Rating: 14°F to 112°F
