Product Information

Full details

The Sea to Summit Ultralight Sleeping Mat is an ideal choice for minimalist backpackers and thru-hikers who need to shave weight without sacrificing a comfortable sleeping surface. Featuring a single layer of Air Sprung Cells, it offers excellent support in a compact package; however, its low R-Value of 1.1 makes it best suited for warm-weather adventures rather than cold-climate camping.

FAQs

Can I use this mat in the snow?

No, this mat has an R-Value of 1.1, meaning it provides minimal insulation. It is designed for warm-weather use.

How do I use the PillowLock system?

The mat comes with self-adhesive hook-and-loop patches that attach to your mat, allowing the corresponding loop on your Sea to Summit pillow to stay in place.

Does the mat come with a repair kit?

Yes, each mat includes a repair kit containing six self-adhesive patches and a spare valve insert.

What is the weight of the Regular size mat?

The regular size weighs 395 grams.

Is the material waterproof?

Yes, the nylon construction and TPU lamination make the surface waterproof, which also makes it easy to wipe clean.

Troubleshooting

The mat is losing air overnight

Check the valve for debris or ensure it is fully closed. Use a soap and water solution to identify bubbles at the puncture site and apply the provided repair patches.

Difficulty inflating with the Airstream Pump

Ensure the connection between the pump sack and the valve is airtight. Use a 'capture and push' motion to trap more volume per roll.

The mat feels too firm or too soft

Use the multi-function valve to release small amounts of air for fine-tuning while lying on the mat to achieve your preferred comfort level.

Pros and Cons

Pros

  • Extremely lightweight at 395g
  • Packs down to a very small size for easy transport
  • Included Airstream pump makes inflation effortless
  • Durable construction with high-quality TPU lamination
  • Secure PillowLock integration

Cons

  • Low R-Value of 1.1 limits it to warm-weather use only
  • Not suitable for winter or extreme alpine conditions
  • Single-layer construction may be less forgiving for side sleepers compared to double-layer models

Setup, Compatibility & Care

Setting up the mat is straightforward thanks to the high-flow, multi-function valve. For compatibility, the mat features the PillowLock system, which works seamlessly with Sea to Summit's range of Aeros pillows.

Care instructions include storing the mat unrolled and with the valve open when at home to allow any trapped moisture to evaporate. If the mat gets dirty, wipe it down with a damp cloth and mild soap; ensure it is completely dry before rolling it back into the storage sack. If you experience a leak, the included repair kit contains six self-adhesive patches to handle minor punctures on the trail.
