Sea to Summit Camp Self Inflating Sleeping Pad

The Sea to Summit Camp Self Inflating Sleeping Pad is a three-season car camping and entry-level backpacking mat with an ASTM F3340-tested R-value of 4.2, built from certified recycled 75D polyester and available in Regular, Regular Rectangular Wide, and Large sizes. Air Zone construction uses body-mapped foam cutouts to place insulation where the body needs it most and reduce weight where it doesn't. The XPEL valve handles both inflation and deflation in a single low-profile unit, and a side-loading stuff sack is included with each size.

Body-Mapped Insulation That Earns Its Weight

Air Zone construction cuts vertical channels through the polyurethane foam in a pattern matched to the body's pressure and heat-loss zones. The result is a pad that carries less foam in low-priority areas without sacrificing warmth or support where a sleeper actually needs it. For campers who want real insulation performance without paying for ounces they won't feel, that tradeoff matters on every trip.

The R-value of 4.2, measured to the ASTM F3340 industry standard, means the Camp pad can be compared directly against other brands' ratings on equal footing. A standardized test removes the guesswork that comes with self-reported or proprietary figures, so a buyer choosing between pads can trust the number.

Contour Shape Designed for How People Actually Sleep

The Contour shape is widest at torso and elbow height, giving side sleepers and restless sleepers room to roll without dropping an arm onto cold ground or sliding off the mat. Sea to Summit states the Contour shape provides 12% more sleep area than a conventional tapered mummy shape with only a minimal weight increase. The Regular Rectangular Wide size extends that width further for sleepers who want maximum spread-out room.

Fast Deflation and a Stuff Sack That Actually Works

The XPEL valve integrates a one-way inflate port, a deflate port, and a fine-tune button in a single unit. Flipping the valve converts the inflate port into a deflate port, which prevents the mat from drawing air back in as it is rolled up, solving a common frustration with simpler valve designs. The included side-loading stuff sack lets a rolled mat drop in from the side rather than being forced in end-on, which is a meaningful time saver at the end of a long day.

Features

• Air Zone Construction: body-mapped foam cutouts reduce weight in low-priority zones while maintaining insulation and support where needed
• R-Value 4.2 (ASTM F3340): independently tested three-season insulation rating comparable across brands
• Contour Shape: 12% more sleep area than a tapered mummy shape, suited to side sleepers and varied sleep positions
• XPEL Valve: single-unit inflate/deflate valve with fine-tune button; flips to deflate mode to prevent air re-entry during rollup
• Certified Recycled 75D Polyester: rugged face fabric made from certified recycled material
• Side-Loading Stuff Sack Included: drop-in side entry makes packing faster than end-on loading

Specifications

Who This Is For and Isn't

The Camp Self Inflating Sleeping Pad suits car campers, canoe and kayak paddlers, and entry-level backpackers who want a durable, well-insulated three-season mat without moving to ultralight construction. The R-value of 4.2 and 4 cm thickness make it a capable choice for spring through fall camping on varied terrain. Side sleepers and taller users (up to 198 cm in the Large sizes) will find a size that fits.

The Camp pad is not designed for ultralight or gram-conscious backpacking. The Regular weighs 840 g and the Large sizes exceed 1 kg, heavier than Sea to Summit's Pursuit line and other ultralight alternatives. The Airstream pump for topping up inflation is sold separately and is not included. The Large Rectangular size may not be available as a TRV variant at time of purchase. Check the size selector.

Common Questions

Is the Camp Self Inflating Sleeping Pad suitable for backpacking?

In the Contour shape, the Camp Self Inflating Sleeping Pad works for backpacking when weight is not the primary concern. It is a capable entry-level backpacking mat, but campers prioritizing the lightest possible pack weight should consider a lighter construction such as Sea to Summit's Pursuit line, which uses a lighter face fabric and Air Light foam construction.

What is the difference between the Contour and Rectangular shapes?

The Contour shape is widest at torso and elbow height, giving side sleepers room to roll without falling off the mat, and saves weight compared to a full-width rectangular design. The Rectangular shape is wider across its full length, providing more space to spread out, but adds weight. The Regular Rectangular Wide and Large Rectangular sizes use the rectangular shape.

How does the XPEL valve work, and do I need a pump?

The XPEL valve on the Camp Self Inflating Sleeping Pad combines an inflate port, a deflate port, and a fine-tune button in one unit. Flipping the valve switches it to deflate mode, which stops the mat from pulling air back in as it is rolled up. The pad self-inflates without a pump; an Airstream pump (sold separately) can be used to top up firmness if preferred.

How does the Camp Mat compare to the Sea to Summit Pursuit?

The Camp Self Inflating Sleeping Pad uses Air Zone body-mapped foam construction and a heavier 75D face fabric, making it more durable and better suited to car camping and paddling. The Pursuit uses Air Light construction and a lighter 20D face fabric, resulting in a lower packed weight for weight-sensitive backpackers. Both use the same XPEL valve system.

What is included with the Camp Self Inflating Sleeping Pad?

Each Camp Self Inflating Sleeping Pad ships with a side-loading stuff sack. An Airstream pump for topping up inflation is not included and is sold separately. No sleeping bag or pillow is included.
