What Our Gearhead(R) Experts Are Saying: "This is hands-down the most comfortable camp mat I've ever slept on. The four inches of foam feel closer to a real mattress than a sleeping pad, and the 6. 5 R-value means I stay warm no matter the season. The multi-function valve makes setup and breakdown painless-essential when I'm car camping often." We bring the Sea to Summit Comfort Deluxe Self-Inflating Mat when we want the luxury of home in the heart of the wilderness. With four inches of plush foam and a soft 30D stretch-knit fabric, it creates a sleeping surface that adapts to temperature and movement, keeping us cozy when cold and cool when warm. Whether we're settling into a quiet campsite or hosting friends in a van build, this mat adds undeniable comfort. Beneath the softness lies Delta Core foam technology, removing over 40% of the foam to reduce bulk while maintaining full-body support. The flip-over multi-function valve simplifies inflation, deflation, and fine-tuning, while the generous R-value of 6. 5 provides dependable insulation for four-season car camping. With sizes ranging from single to double, the Comfort Deluxe transforms any basecamp into a restorative retreat.
