But no rule without exceptions and sometimes a shorter torso length is better, for example in alpine or mountaineering situations where a short back allows easy access to the climbing harness. The center of the hipbelt ideally rests on the hip bone crest (pelvis) in order to bear the bulk of the load (refer to diagram) especially on large internal frame backpacks. Defining torso length is not necessarily critical on a daypack but crucial on backpacking or alpine touring packs, as only perfect fit can warrant transfer of a bulk of the pack weight to the hips. Vertical 3-dimensional sidewalls allow the top surface to extend all the way out to the edge of the mat without tapering, maximizing the usable sleeping surface – just like a bed at home! Our double-wide duo version comfortably sleeps two people.ĭepending on pack volume and intended use the suspension system of a backpack becomes an essential feature.

The inflate valve is equipped with a one-way flapper, allowing air to easily be purged during the night and with just the touch of a fingertip if you find the mat is too firm. Inflate and deflate valves are large, high flow-rate FlatValves™ – an EXPED “firstovation” (first-ever innovation). An EXPED Mini Pump is included to top-off the inflation and achieve the preferred firmness. When the inflate valve is opened, the foam expands and draws air into the mat. To enhance the cradling effect, like a high-end home-based bed, the mat’s surface features a brushed, stretch tricot polyester that relieves pressure points (hips and shoulders) while evenly supporting the body across all surfaces, head to foot. Horizontal air channels in the foam help reduce weight and packed volume without sacrificing comfort. MegaMat Duo 10 has at its core 10 cm (4”) of just-the-right density, Oeko-Tex 100 certified, open-cell polyurethane foam for support and warmth. MegaMat is our original, most comfortable, best-reviewed sleeping mat, making truly luxurious sleep a reality for thousands of car campers and overland enthusiasts everywhere since its introduction in 2011.
