Ultra 5R Mummy

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.

We include a temporary repair kit with an adhesive patch for quick fixes while out on a trip. Simply follow the instructions in the repair kit that came with your mat.

For more permanent repairs we recommend the EXPED Mat Field Repair Kit. You can also employ the use of some helpful repair tools from our friends over at GEAR AID such as Tenacious Tape and Seam Grip. We've included some helpful repair videos below on how to use all of these items.

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.

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