The EquilibrateTM Jacket creates the required climate balance when alternating between stamina and short high-level interval performances. This is achieved thanks to the best possible moisture transport and vapour permeability, combined with partial insulation and active aeration zones in which air circulates due to the increase in body warmth. This leads to the creation of dynamic thermal dissipation zones, which adjust to meet the body’s requirements. Uniquely combined materials and structures are able to meet contradictory requirements in a second layer: it cools when perspiring and warms when chilling.
