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!

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 over-inflate 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. 

All fabrics used in our sleeping mats are OEKO-TEX® 100 certified. This means they are free of any flame retardant and DWR (durable water repellency) chemicals.

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

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.

We include textile glue in our repair kits that is designed for field use because of its short dry time. Follow the instructions in the repair kit that came with your mat.  For even faster, more permanent repairs we recommend the EXPED MAT FIELD REPAIR KIT.

Do not use rubber cement, duct tape, or plumber’s tape to try to repair punctures, tears, or valves.

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.

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.

Although used gear (purchased second-hand) is not covered under warranty, we will gladly repair any Exped product we think is salvageable in order to keep our gear out of the landfill for as long as possible. For customers in the USA, please send us your information by filling our WARRANTY AND REPAIR SERVICE REQUEST form to get started with the repair process.

Unfortunately, we do not have the resources to manufacture custom-sized mats for our customers.
