Artemis 8.3 R-Value for cold nights

The Gear Doctors Artemis sleeping pad uses an air-foam hybrid core to deliver an 8.3 R-value, rated for four-season warmth down to extreme cold. It expands to 79 by 27.2 inches with a 4-inch thickness and supports up to 450 pounds. The single-size mat weighs 6.4 pounds and packs to 27.2 by 9.4 inches. It is built for adult campers who need reliable insulation without a bulky footprint.

Self-inflation reaches 80 percent in five minutes

Opening the valve lets the foam core draw air automatically, taking the pad from flat to 80 percent inflation in about five minutes with no lung power required. The included pump sack tops off the remaining 20 percent quickly and doubles as the storage pouch. Medium firmness can be adjusted by adding or releasing air through the same valve. No external power or battery is involved.

Pump sack, repair kit and carry bag included

The pump sack serves as both inflation tool and stuff sack, cutting the number of separate items you must pack. A repair kit with patches and instructions is supplied for field fixes if the fabric is punctured. The carry bag holds the rolled pad, pump sack and repair kit together. Buyers who need a built-in pillow, integrated sheet system or electric pump will not find those features here.

Questions about this item

How do I use the pump sack to finish inflating the pad after the valve reaches 80% in 5 minutes?

Switch the valve to inflation mode and wait five minutes for the pad to reach 80% inflation, then attach the pump sack and add air until the pad feels firm at 100%.

What should I do if the polyester shell gets a puncture while camping?

Use the included repair patch kit and follow the supplied instructions to seal the hole before the next use.

Will the 8.3 R-value and 450-pound capacity hold up for a heavier sleeper on cold ground night after night?

The pad is rated for a maximum weight of 450 pounds and an R-value of 8.3, so it will support a heavy sleeper and resist cold transfer through repeated nights.
