What is Outlast and how does it keep me cool?

Outlast is a proactive temperature-regulating technology originally developed for NASA to protect astronauts from extreme temperature fluctuations in space.

Unlike traditional materials that simply wick away sweat, Outlast manages heat before perspiration begins.
The technology utilizes Phase Change Materials (PCM), specifically microencapsulated natural wax (derived from rapeseed oil), which Outlast calls Thermocules.

When you are hot, the Thermocules absorb and store excess body heat as the wax melts from a solid to a liquid state.
As your body temperature drops, the stored heat is released back to you as the wax re-solidifies.
This continuous cycle creates a balanced “microclimate” next to your skin, reducing sweat production by up to 48%
