Sea to Summit Camp Plus Self-Inflating Sleeping Pad review

The Camp Plus is Sea to Summit's step down from the Comfort Deluxe, and it is the best value among the pads we compared that carry a lab-tested warmth rating. Its ASTM R-value of 5.3 covers extended three-season trips, and at 7 cm, or 2.76 inches, it is 33% thicker than the brand's standard self-inflating mats. Air Zone construction cuts body-mapped holes through the foam, keeping insulation under the torso and trimming weight elsewhere, so the Regular weighs 37.0 oz and packs to 11 by 6 by 6 inches. The Contour Shape is widest at the elbows and gives 12% more area than a tapered mat, and rectangular sizes are available too. The XPEL valve handles firmness and deflation. Sea to Summit says it suits short hikes to a campsite but is a little heavy for backpacking. A pump sack is sold separately, and the pad is thinner than any 4-inch pick.
