Sea to Summit Self Inflating Camp Sleeping Mat Wide

The R Value of 4.2 indicates the mat's resistance to heat flow. A higher R Value means better insulation. This mat is suitable for cooler temperatures down to approximately -5°C.

Once unrolled and mostly self-inflated, you can open the valve and add a few breaths of air manually to reach your preferred firmness. The mat is designed for this to optimize comfort.

The packed dimensions are approximately 34 x 15cm, making it relatively compact for its insulation and width.

With an R Value of 4.2, it offers good insulation for colder conditions and is suitable for three-season use and mild winter camping down to -5°C. For extreme cold, consider a higher R Value mat or using it in conjunction with a closed-cell foam pad.

Clean the mat using a damp cloth and mild soap. Avoid harsh chemicals. Ensure it is completely dry before storing to prevent mold or mildew.

Information on specific warranty periods is best obtained from the retailer or the manufacturer's official website, as it can vary.

This mat is self-inflating and designed to be topped up with breath. While a pump might technically connect, it's not designed for it and could potentially damage the internal foam or valve.

Ensure the valve is fully open. Check for any debris blocking the valve. Allow more time for self-inflation or add a few breaths manually. If the mat is old, the internal foam may have compressed slightly.

Check that the valve is securely closed. Inspect the mat for any punctures or tears and repair them using a patch kit. Ensure the mat is not placed near sharp objects.

Open the valve(s) fully. Press down on the mat from the opposite end of the valve to expel air. Roll the mat tightly, starting from the end opposite the valve, while continuing to press air out. Store the mat unrolled or loosely rolled when possible to maintain foam integrity.
