Sea to Summit's Camp Mat Self Inflating Sleeping Mat is a supportive and durable sleeping mat that won't let you down.

Sea to Summit says:

This is a great option for the customer wanting a self-inflating mat at more affordable price point. The Camp Mat is a 1.5” thickness foam mattress that utilizes our Delta Core-V™ vertical coring to remove unnecessary weight and minimize packed size. A 75-Denier polyester top and bottom fabric offers excellent wear and durability. With an R 4 insulation rating this mat series offers 3-season warmth and comfort.

Sea to Summit's Camp Mat Self Inflating Sleeping Mat is a durable and reliable 3 season sleeping mat. The 75 denier fabric is really tough and if you are unfortunate enough to suffer a puncture thanks to the foam you will still get some support unlike with a inflatable mattress.

The Camp mat will slowly self inflate but if your impatient like me a few breaths will soon get it fully inflated. Thanks to the multi function valve inflation and deflation is one way. The zoned Delta core technology gives you support and warmth where you need it to keep the pack size relatively small.

  • Weighs: 750g (excluding storage bag)
  • Dimensions: 183 x 51 x 4cm
  • Packed Size: 16 x 26 cm
  • ASTM R-Value: 4.2

ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
