Camping luxury has a new look and feel with the Comfort Plus™ Self Inflating Sleeping Mat. This is a plush, 3-inch thick, light and easy to use option for anyone looking for maximum comfort. The Delta Core™ technology removes weight and bulk without compromising comfort.  A lightweight but luxurious 30D stretch knit fabric is used on the top surface and each mat is embossed with a non-slip grip print to keep your sleeping bag on the sleeping mat. We've literally put a twist on our multi-function valve to ensure super-fast deflation without fighting re-inflation as you roll it up.

  • This luxurious fabric has been engineered to provide you many nights of camping comfort

Is the Comfort Plus Self-Inflating Sleeping Mat...?

  • Insulated well enough for three-season temperatures? Yes. The Comfort Plus SI Mat has a tested R-Value of 4.1 – suitable for anything but really cold ground.
  • Small enough when packed to use for backpacking? Possibly. If you are only hiking for a short distance, the weight (34ozs) and packed size (7” x 10”) – both size Regular – could work. For longer trips an air mat would be a better option– see below.
  • Easy to pack up? Relatively easy. The flip-over valve prevents the mat from drawing air back in while it is being rolled up – but the larger sizes (including the Double) still require a little effort to pack into their stuff sacks.
