Quality & Materials

Uses Outlast Gold certified fabric, the highest capacity of PCM available. The shell is 100% cotton with a 300 thread count, ensuring breathability.

Evidence & Testing

Outlast technology is a 'Certified Space Technology' and has undergone extensive testing for thermal management in extreme environments.

Brand Transparency

Slumber Cloud provides clear information on the 'Gold' vs 'Silver' cooling levels and full material disclosures.

Value Assessment

Excellent entry point for cooling. While it won't 'chill' like a powered unit, it is the most effective passive solution for the price.

Why Not Alternatives?

Superior to standard 'cooling gel' pads which eventually saturate with heat; the PCM technology actively cycles heat away from the body for a longer duration.
