Arc’teryx Layering Guide
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.
