Layering

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.

Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
