Protect the core of your body with this high-tech vest developed for dynamic alpine activities. Its waterproof and windproof build with MEMBRAIN 115 has minimal bulk and athletic fit to promote movement. But the real secret is on the inside: the soft BUFFERCONE fabric retains heat through its special three-dimensional structure, while providing the right ventilation to keep the body dry. The UYN SPIRE vest features increased breathability thanks to HALOFLEX inserts on the shoulders that allow moisture to escape quickly during intense exertion.
