When running in winter with uncertain weather, what you need is a balance between protection and breathability: don't let cold or humidity affect your performance, and at the same time prevent your body from overheating. The UYN CORESHELL vest is the most advanced solution ever made. Its principle is simple: it protects the front, like a softshell, and lets your back breathe, like a shirt. To give you insulation where you need it, we have introduced our bodymapped BUFFERCONE technology in the inner layer. Buffercone represents a revolution: it retains body heat in areas subject to cooling and creates an insulating cushion. For an extra touch of protection against wind and light rain, we have used the exclusive MEMBRAIN115 membrane on the front, characterized by a very high extension capacity.

Vest for extra protection from cold and wind while running


Waterproof and breathable at the same time. UYN’s exclusive intelligent membrane sets completely new standards in terms of weather protection, elasticity and wearing comfort. Unlike traditional membranes, Membrain115 does not limit the elasticity of the fabric to which it is paired, allowing it to be flexible and comfortable.

 The human body produces heat, the most effective form of insulation is that which prevents its loss. UYN technicians have developed a material with an innovative structure that is highly effective in retaining heat. This permits a three-dimensional, baggy surface structure in which heated air is trapped in so-called “buffer cones”, thus generating a buffer zone. Unlike conventional fleece materials, the thickness of the structure can be adjusted as desired. Based on the mapping of the heat distribution produced by the human body, it is possible to create areas with high, medium and low insulating power.
