Our Verdict

The Expedition Insulated Sleeping Mat weighs 685g, measures 198 × 68 × 11 cm, and has an R-Value of 6.6, making it well-suited for cold-weather trips. I’ve found the IRL insulating layer does a great job of retaining heat, and combined with the down fill, it provides a warm, cushioned sleep even on frozen ground. The 11 cm depth adds a sense of plushness—fantastic for side sleepers, and there’s enough thickness to smooth out uneven ground. The outer fabric feels tough enough to handle abrasive surfaces yet light enough to keep the overall weight reasonable for an insulated mat.

It inflates easily and deflates without fuss. The rectangular shape means that you have a little more room to toss and turn if you’re a restless sleeper like me. For cold-weather trips where reliable insulation is critical, it’s a solid, dependable choice.
