Rukka Outlast Base Layer Shirt

Introduction

Rukka Outlast Shirt

The Rukka Outlast Shirt works to keep the riders temperature not too hot, not too cold, but just right, over a broad range ofenvironments and activity levels.When your activity level or the outside temperature increases, the Outlast thermocules begin to change from a solid to a liquid which provides you with a comfortable sensation ofthermal equilibrium. The energy required to activate this process comes from your warm body or risingambient temperatures.

When you begin to cool down, Outlast thermocules begin to change back from a liquid to a solid. In this phasechange, 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.
