Sea to Summit Camp Plus Self Inflating Sleeping Pad

The Sea to Summit Camp Plus Self Inflating Sleeping Pad is a three-season car camping and hunting pad rated at ASTM R-Value 5.3, with a 7 cm (2.76 in) open-cell foam core that self-inflates and an XPEL valve for fine-tuning firmness. Body-mapped Air Zone construction places insulation where the body needs it and removes foam where it doesn't, keeping weight lower than a uniform-foam design at the same thickness. The Camp Plus is available in four sizes: Regular, Regular Rectangular Wide, Large, and Large Rectangular.

Built Thicker for Real Sleep

At 7 cm, the Camp Plus is 33% thicker than standard self-inflating mats. That extra depth puts more foam between a sleeper and the ground, reducing pressure points on hips and shoulders during a full night's rest at a base camp or car camping site. The XPEL valve lets a sleeper add or release small amounts of air to dial in firmness, so the pad works for back sleepers who want a firmer surface and side sleepers who prefer a softer one.

Air Zone Construction Keeps Weight in Check

Sea to Summit's Air Zone construction cuts vertical channels through the foam in a body-mapped pattern. The channels are wider in zones where a sleeper's weight is lightest and narrower where support and insulation matter most. The result is a pad that carries less foam overall without giving up warmth or support where the body actually contacts the surface.

Contour Shape Adds Sleep Area Without Bulk

The Camp Plus uses a contour shape that is widest at torso and elbow level. Sea to Summit states this geometry adds 12% more sleep area compared to a conventional tapered (mummy) shape, giving side sleepers room to roll without arms or hands dropping off the edge onto cold ground. The Regular Rectangular Wide and Large Rectangular sizes extend that width further for sleepers who want maximum room to move.

Features

• ASTM R-Value 5.3: independently lab-tested to the ASTM F3340 standard for three-season ground insulation
• Air Zone Construction: body-mapped vertical foam cutouts reduce weight in low-load zones and retain insulation where it counts
• XPEL Valve: integrated inflate, deflate, and fine-tune ports in one low-profile unit; flipping the valve converts it to a one-way deflate port for tighter rolling
• Contour Shape: 12% more sleep area than a tapered shape (contour sizes); rectangular sizes offer additional width
• Recycled Face Fabric: certified recycled 75D woven polyester with TPU lamination
• Side-Loading Stuff Sack: included; drop the rolled mat in from the side rather than forcing it in end-first

Specifications

Who This Is For and Isn't

The Camp Plus suits car campers, hunters, and paddlers who drive or carry gear to a site and want a thick, comfortable pad with reliable three-season ground insulation. The R-Value 5.3 rating and 7 cm depth make it a strong choice for shoulder-season camping where cold ground is a real concern. Sleepers up to 183 cm (72 in) fit the Regular and Regular Rectangular Wide; those up to 198 cm (78 in) fit the Large and Large Rectangular.

The Camp Plus is not well suited for backpacking-focused trips where pack weight is a priority. It is a little heavy for that use. An Airstream pump for topping up via the XPEL valve is sold separately and is not included.

Common Questions

Is the Camp Plus Self Inflating Sleeping Pad suitable for backpacking?

The Camp Plus Self Inflating Sleeping Pad is suitable for short hikes to a campsite but is a little heavy for backpacking-focused trips where minimizing pack weight is the priority. Campers who drive or paddle to a site will find the weight more acceptable given the comfort the extra thickness provides.

How does the Camp Plus self-inflate?

The Camp Plus has an open-cell polyurethane foam core that draws air in on its own when the XPEL valve is opened, much like a sponge expanding. After the foam has drawn itself full, a small amount of additional air can be blown in through the inflate port to bring the pad up to the desired firmness.

How does the XPEL valve work for deflation?

To deflate the Camp Plus, the XPEL valve is flipped over, which converts the one-way inflate port into a one-way deflate port. This prevents the foam from drawing air back in as the pad is rolled up, allowing for a tighter, more compact roll and easier packing into the included stuff sack.

How does the Camp Plus differ from the Pursuit Plus?

The Camp Plus uses body-mapped Air Zone construction and a heavier 75D face fabric, making it more durable and better suited to base-camp and car camping use. The Pursuit Plus uses lighter Air Light construction and a 20D face fabric, which reduces weight for users who need a more packable option.

What is included with the Camp Plus Self Inflating Sleeping Pad?

The Camp Plus Self Inflating Sleeping Pad comes with a side-loading stuff sack. An Airstream pump compatible with the XPEL valve is sold separately and is not included in the box.
