The UYN FULLSHELL jacket is the indispensable garment in every cyclist's layering system, engineered to support him throughout that winter period when temperatures go from mild to cold, without reaching the extremes of the coldest days. In order to achieve the perfect balance between comfort, protection and insulation, we have created a true masterpiece of textile engineering: a three-layer fabric with our intelligent MEMBRAIN115 membrane, which protects against splashes of water and icy wind, and an inner surface with BUFFERCONE bodymapped technology, which retains body heat providing perfect insulation where needed. In the back area of the sleeves, shoulders and neck we opted for a high elastic and lighter fabric to increase breathability. Thanks to the ERGOMOTION design, the two different fabrics join together in the scapular area without creating creases and constrictions.
