When camping with the Camp Mat Self Inflating (Regular), you'll appreciate 1.5 inches of insulation, keeping you away from the hard ground. Delta Core-V technology keeps body contact areas warmer throughout the Spring, Summer and Autumn seasons.  The multi-functional valve twists to allow the mat to be rolled tightly without reinflating on the go and with a durable 750D polyester face fabric, it's also tough and hardwearing.
