Sea to Summit Ultralight Air Sleeping Pad

The Sea to Summit Ultralight Air Sleeping Pad is a single-layer air sprung cell mat built for ultralight backpackers who need the lightest and smallest packed size without giving up the contouring comfort of individually air-filled cell construction. With an R-value of 1.1 and a 5 cm inflation thickness, it is designed for warm-weather use. The pad is available in three sizes (Small, Regular, and Large) to match a range of user heights.

Air Sprung Cell Construction: Comfort Without the Weight

The Ultralight Air Sleeping Pad uses a single layer of medium-resolution air sprung cells: hundreds of small, interconnected air-filled chambers that individually conform to the body's contours and distribute weight across the full surface of the mat. Unlike a conventional air pad, which relies on a single large air chamber, this cell structure provides multiple points of suspension, reducing pressure points at the hips and shoulders without requiring extra thickness or added insulation layers. The result is a mat that sleeps more evenly than its weight suggests.

Integrated Airstream Pump Sack: Fast Inflation, No Dizziness

The included stuff sack doubles as a high-volume Airstream pump. One end stows the rolled pad; the other unfolds into a pump chamber that inflates with a single breath and fills the mat in two or three pump cycles. Inflating by pump rather than directly by mouth keeps condensation moisture out of the pad's interior and eliminates the dizziness that comes from blowing up a mat by lung power alone. The multi-function valve then allows fast fine-tuning of firmness and quick deflation at pack-up.

Extrusion TPU Lamination: Durability Built Into the Fabric

The 30D/40D ripstop nylon face fabric is bonded to a TPU airtight layer using an extrusion lamination process rather than roll-to-roll lamination. Extrusion lamination bonds the TPU directly to the nylon at a molecular level, making delamination significantly less likely over years of use. The internal laminate also carries a permanent antimicrobial treatment to prevent mold from forming inside the mat from residual condensation moisture. A proprietary outer coating reduces surface slipperiness and increases water resistance; self-adhesive repair patches are included for field puncture repair.

Features

• Integrated Airstream Pump Sack: stuff sack unfolds into a high-volume pump; inflates the mat in two to three cycles with no mouth inflation required
• Air Sprung Cell construction: single layer of medium-resolution interconnected cells conforms to body contours and distributes pressure across the full mat surface
• Multi-function valve: supports fast inflate, fast deflate, and incremental firmness adjustment
• Extrusion TPU lamination: bonds TPU to nylon face fabric to resist delamination; internal layer carries a permanent antimicrobial treatment
• Self-adhesive repair patches included: for field puncture repair

Specifications

Who This Is For and Isn't

The Sea to Summit Ultralight Air Sleeping Pad suits ultralight backpackers and warm-weather campers who prioritize pack weight and compressed size. The Small fits users up to 168 cm (66 in), the Regular up to 183 cm (72 in), and the Large up to 198 cm (78 in), giving most backpackers a size-matched option.

This pad is not suitable for cold-weather or winter camping. With an R-value of 1.1 and no internal insulation, it is intended only for warm-weather conditions. Campers who need three-season or cold-weather insulation should select an insulated sleeping pad with a higher R-value.

Common Questions

Is the 5 cm thickness enough to sleep comfortably?

Thickness alone does not determine sleeping pad comfort. The number of points of suspension does. The Sea to Summit Ultralight Air Sleeping Pad uses hundreds of individually air-filled cells that support body weight like a pocket-sprung mattress, distributing pressure evenly across the mat surface regardless of the 5 cm inflation height.

How do you inflate the Ultralight Air Sleeping Pad?

The included stuff sack has an integrated Airstream pump built into one end. A single breath inflates the pump chamber, and two or three pump cycles fill the mat. This method keeps condensation moisture out of the pad's interior and avoids the dizziness that comes from inflating directly by mouth.

Does the pad make noise when you move during the night?

The outer laminate material of the Sea to Summit Ultralight Air Sleeping Pad is designed to be quiet during use. Movement during sleep does not produce the crinkling noise associated with some air pads.

Is this pad suitable for cold-weather camping?

No. The Sea to Summit Ultralight Air Sleeping Pad has an R-value of 1.1 and no internal insulation layer, making it suitable only for warm-weather camping. For cold or three-season conditions, an insulated sleeping pad with a higher R-value is required.
