Product Description

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 2011.

Mega in size, comfort, and warmth, the MegaMat Duo 10 has at its core 4-inches of comfortable open-cell polyurethane foam for exceptional support. Horizontal air channels within the foam help reduce weight and packing size without sacrificing comfort.

The unique 3D construction offers the largest possible sleeping area. To enhance the cradling effect, the mat’s surface features a soft stretch tricot polyester that relieves pressure points (hips and shoulders) while ensuring a delightful feel against the skin.

The MegaMat is designed to self-inflate. Using the included EXPED Mini Pump, you can effortlessly achieve your desired level of firmness. The two flat valves make both inflation and deflation quick and easy. We also provide our convenient Sidewinder Bag for hassle-free packing.

  • 3-D construction

    Vertical sidewalls ensure the biggest possible sleeping surface — just like your bed at home!

  • Separate inflate & deflate valves

    Adjust firmness by tapping on the one-way inflate FlatValve to release small amounts of air. Use the deflate valve plus the inflate valve pin to speed up deflation.

  • Luxurious surface material

    The soft & stretchy tricot polyester face fabric ensures maximum next-to-skin comfort and enhances the cradling effect for a truly luxurious sleep experience.

  • Self-inflating mat

    Open the one-way inflate valve & insert the valve pin to speed up inflation. Mini pump included to top off up air to your desired firmness.

  • Comfortable foam support

    4" of soft open-cell foam provide premium comfort & warmth.

  • Repair kit & stuff sack included

    Adventures happen. Patch small punctures & tears with our included mat repair kit. The rolltop SideWinder stuff sack is height adjustable, perfect for the quick "messy roll."

What is R-value?

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!

Can I use an electric pump to inflate my mat or pillow?

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.

What do I do if my MegaMat isn't inflating on its own?

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.

How do I clean my mat?

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.

How should I store my mat?

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.
