MegaMat 10

R-value is a measure of thermal resistance. It indicates the efficiency of insulation by measuring its resistance to heat transfer. The higher the number, the slower the rate of heat transfer through an insulation.

In EXPED sleeping mats, higher R-values help sleepers retain the heat their bodies generate and the result is the pleasant and sometimes elusive condition called warmth!

You can use the EXPED Widget electric pump to inflate your mat. The Widget is relatively low power and can be used for all EXPED mats and pillows. We do not recommend the use of any electric pumps other than the Widget because overinflating your mat or pillow can cause irreparable damage.

When our mats are stored in a compressed state for prolonged periods, the interior foam gets used to its compressed (rolled-up) shape and can cause sluggish self-inflation of the mat.

We also like to point out (since many overlook it) that the mats come with an “inflation wedge” (looks like a zipper pull) piece next to the inflate valve. This is designed to be inserted between the plastic valve wall and the green silicone “flapper” seal to create an adequate gap for air to enter the mat. If your mat’s foam seems compressed, filling the pad to full inflation (until the mat is firm) and leaving it inflated for a few hours should be enough to de-compress the memory foam and restore the mat's self-inflating ability for subsequent uses.

The first step is to make sure all valves are fully closed. We recommend cleaning your mat with warm water and a mild soap. Do not use bleach to clean your mat. If needed, you can use a rag or soft sponge to carefully scrub the mat.

After using soap, rinse it well. The mat should air dry after cleaning. Do not put your mat in a washing machine or dryer.

Store your mat in a cool, dry place, unrolled with the valves open and out of reach of pets with claws.

Rooftop Tents:

It’s fine to use and store the mat in a rooftop tent while on a trip, but in warmer climates, we recommend leaving the valve caps open during the daytime as a precaution so that the mat cannot overinflate from the heat of sun exposure.

In general, it's good to keep the mat somewhere cool and dark to minimize damage from excessive heat or UV radiation. It’s also best not to keep your mat in a rooftop tent year round for long-term storage.
