Rukka Outlast Pants

Rukka Outlast Outlast technology was originally developed for NASA and utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. Outlast works as a thermal shock absorber by slowing the rate of temperature change within a wearer's personal microclimate and reduces the rate at which a person will overheat or get cold. Pants

The Rukka Outlast Pants work to keep the rider’s temperature not too hot, not too cold, but just right, over a broad range of environments and activity levels. When your activity level or the outside temperature increase, the Outlast thermocules begin to change from a solid to a liquid which provides you with a comfortable sensation of thermal equilibrium. The energy required to activate this process comes from your warm body or rising ambient temperatures.

When you begin to cool down, Outlast thermocules begin to change back from a liquid to a solid. In this phase change, the energy that was absorbed by the thermocules while you were active is returned to you. The Rukka warranty is valid for 5 (five) years from the date of purchase against faults in material or workmanship.
