Full details

The Rab Stratosphere 5.5 Sleep Mat is designed for trekkers, climbers, and backpackers seeking a lightweight yet warm sleeping solution for all-mountain adventures. Its key benefit is a superior warmth-to-weight ratio thanks to Stratus R insulation and a compact pack size. A potential caveat is its 8cm thickness, which may be less supportive for some users compared to thicker mats.

Troubleshooting

Mat not fully inflating

Ensure the valve is fully open and check for any debris obstructing it. Use the pump sack to add more air, being careful not to over-inflate.

Mat deflating during the night

Check that the two-way valve is securely closed. Inspect the mat for any punctures and use the repair kit if necessary. If a leak is suspected, submerge the partially inflated mat in water to find the source.

Reduced warmth

Ensure the Stratus R insulation is not compressed and is dry. Check that the valve is sealed properly to prevent cold air ingress.

Pump sack not attaching correctly

Ensure the valve on the sleep mat is in the correct position for pump sack attachment and that there are no obstructions on either the valve or the pump sack connector.

Pros and Cons

Pros

  • Designed to keep users centered and prevent rolling off.
  • Quick and hygienic inflation with the included pump sack.
  • Durable and water-resistant outer fabric.
  • Suitable for a variety of sleeping positions due to its shape.

Cons

  • 8cm thickness may not be sufficient for users requiring maximum cushioning.
  • The R-value of 5.5 is suitable for 3-season use but may not be warm enough for extreme winter conditions.
  • As a self-inflating mat with a pump sack, it requires active inflation.
  • Weight of 930g for the Regular Wide version might be a consideration for ultralight backpackers.

Setup, Compatibility & Care

Setup:

  1. Unroll the sleep mat and open the low-profile two-way valve. Allow it to self-inflate partially. Some initial inflation may be needed.
  2. Attach the included pump sack to the inflation valve and use it to fully inflate the mat to your desired firmness. Avoid over-inflation.
  3. Close the valve securely.

  • Compatible with standard sleeping bags.

Care:

  • Cleaning: Clean the mat using a damp cloth. Avoid harsh detergents or abrasive cleaners. Ensure the mat is completely dry before storing.
  • Storage: Store the mat loosely rolled in its included stuff sack, away from direct sunlight and extreme temperatures. Do not store it fully compressed for extended periods.
  • Repairs: Use the included repair kit for small punctures. Ensure the area is clean and dry before applying patches.
