On Weather Vest

On ThermaTec™: Advanced insulation technology developed by On for stable thermal comfort in cold conditions. It combines ultra-lightweight synthetic fibres with an adaptive structure that effectively traps heat but also allows for rapid moisture wicking. The material responds to temperature changes: it opens up for better ventilation during increased exertion, and keeps heat close to the body at rest. Thanks to its elasticity, it does not restrict movement and remains comfortable even when worn for long periods of time. The technology can be found in jackets, running layers and outdoor gear, where it provides the ideal balance between warmth, breathability and light weight.

13% Elastane: used in combination with other materials, especially for its excellent flexibility - its fiber can stretch up to three times its normal length and then return to its original state.
