Details The Swix Men's Triac 3.0 Vest is one of the most versatile cross country ski tops around. It's the extra layer you need when just a base or mid layer isn't enough to keep your core warm. It's the centerpiece over a lightweight jacket to add a layer of wind resistance without adding bulk. This vest from Swix is a fully windproof, stretchy, and air permeable softshell up front with a lightweight full stretch and highly breathable rear. This design cuts through windchill while skiing and lets excess heat and moisture escape when needed. It's a high-performance top designed to be used in high-output activities like skiing but will work equally well for running and cycling in colder temperatures!
