Sea to Summit Pursuit Plus Self Inflating Sleeping Pad

The Sea to Summit Pursuit Plus Self Inflating Sleeping Pad is a 7.5 cm thick, self inflating mat built for comfort-oriented trekkers, hunters, and paddle tourers who want genuine sleeping-pad cushion without sacrificing packability. Horizontal Delta Coring removes 40% of the foam and replaces it with foam-supported air channels, delivering substantial support at a weight competitive with thinner pads. An ASTM F3340-tested R-value of 4.2 makes the Pursuit Plus a capable three-season mat. Four size and shape variants cover a wide range of sleepers: Regular Contour, Regular Rectangular Wide, Large Contour, and Large Rectangular Wide.

Foam-Supported Comfort Without the Bulk

Horizontal Delta Coring is a Sea to Summit construction method that removes 40% of the foam core and leaves behind delta-shaped channels. Those channels fill with air when the mat self-inflates, creating a surface that combines the stability and quiet of foam with the cushioning of an air pad. At 7.5 cm of loft, the Pursuit Plus sits noticeably thicker than most self-inflating mats in its weight class, which translates directly to pressure relief at the hips and shoulders over a full night on uneven ground.

Sleep in Any Position, All Night

The Contour shape widens from the torso to the shoulders, adding 12% more sleep area in the zone where side sleepers and back sleepers need it most. That extra width means elbows stay on the mat when you roll over, reducing the mid-night adjustments that interrupt sleep on narrower tapered pads. The Rectangular Wide shape extends that width across the full length of the mat for sleepers who want unrestricted room to move. Because the Pursuit Plus is a self-inflating foam-core mat rather than an air pad, the materials and construction produce very little noise when you shift positions.

Low-Impact Materials, Straightforward Packing

The shell fabric is a 20 denier, solution-dyed, 100% post-consumer recycled polyester certified to the Recycled Claim Standard and approved by bluesign. Solution dyeing adds color to the polymer before the fiber is extruded, reducing water use, energy, and CO2 emissions compared to conventional dyeing, and producing a color that runs throughout the yarn rather than sitting only on the surface. The fabric carries no PFAS treatments and no flame-retardant coatings. The XPEL Multi-Function Valve integrates a one-way inflate port, a deflate port, and a fine-tune button in a single low-profile unit; flipping the valve converts it from inflate mode to deflate mode, preventing the mat from drawing air back in as it is rolled up. A side-loading stuff sack and a repair kit are included. The Pursuit Plus is part of Sea to Summit's 1% for the Planet commitment.

Specifications

Who This Is For and Isn't

The Pursuit Plus suits comfort-oriented campers, trekkers, hunters, and paddle tourers who prioritize sleeping-pad thickness and cushioning over minimum pack weight, and who need a three-season mat rated for temperatures where an R-value of 4.2 is sufficient. The Regular sizes fit sleepers up to 183 cm (72 in); the Large sizes fit sleepers up to 198 cm (78 in).

The Pursuit Plus is not designed as an ultralight backpacking pad for gram-conscious hikers where every ounce is critical. Air pads in the same thickness class weigh less. An R-value of 4.2 is not rated for winter or extreme-cold conditions. The Airstream pump, which fits the XPEL valve for topping up inflation, is sold separately and is not included.

Common Questions

What is the difference between the Contour and Rectangular Wide shapes?

The Pursuit Plus Contour shape widens from the torso to the shoulders, providing 12% more sleep area in that zone compared to a standard tapered pad, giving side sleepers and back sleepers room to roll over without elbows falling off the edge. The Rectangular Wide shape extends full width along the entire length of the mat, giving sleepers who want the most possible room to spread out the maximum surface area without the weight penalty of a wider pad in a narrower shape.

Does the Pursuit Plus contain PFAS or flame-retardant treatments?

The Pursuit Plus Sleeping Pad contains no PFAS treatments and no flame-retardant coatings. Sea to Summit states that all of its sleep products, including sleeping pads, sleeping bags, liners, and pillows, are non-PFAS and flame-retardant free.

Is the Pursuit Plus noisy when you move on it during the night?

The Pursuit Plus Self Inflating Sleeping Pad is quieter than a typical air pad. The self-inflating foam-core construction and the soft, textured recycled polyester shell produce very little sound when a sleeper shifts positions, making it a practical choice for light sleepers or shared tent situations where pad noise would be disruptive.
