Sea to Summit Comfort Plus Self Inflating Sleeping Mat

  • Product Number: 5435 - 8403327

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.
