Outlast®

NASA space technology, now on your bed. Our Outlast® collection uses Phase Change Material (PCM) – originally developed for astronauts – to actively absorb, store, and release heat. It keeps your skin in the 31°C–33°C comfort zone all night long. From cooling comforters for adults and kids, cooling sheets and cooling pillowcases, to body pillows and travel pillows – every piece delivers the same active temperature control. No more night sweats or kicking off blankets. Sleep steady, sleep deep.

How Does Outlast® PCM Work?

Science Behind Outlast®

PCM（Phase Change Material）Microcapsule is tiny capsule with a rapeseed-derived shell and a paraffin-based wax core. Integrated into textiles, these microcapsules absorb, store, and release heat to maintain a stable, comfortable microclimate.

Skin Temperature Stabilization

Outlast® technology goes beyond conventional passive contact cooling or one-way moisture wicking. Utilizing patented Phase Change Materials (PCMs), it offers active two-way temperature control (28°C–32°C). This continuous, adaptive process delivers equilibrium, not just a momentary sensation.

FAQs about Outlast®

Q1： What is Outlast® and how does it work?

Outlast® is a NASA‑born phase change material (PCM) technology. It uses microcapsules that absorb heat when you’re too warm and release it when you’re too cool – keeping your skin temperature stable between 31°C–33°C for all‑night comfort, ideal for hot sleepers.
