Choosing the right layer for crisp spring mornings and chilly fall nights can be a challenge. Our Men's Ventum Shell is crafted to cut the breeze and trap warmth in your base layer or against your skin. Ventum fabric strikes the right balance between cutting cold wind while still allowing enough breathability for sweat to escape when hiking on chilly mornings and evenings. Ventum fabric tests at 39.5 CFM under ASTM D-737. It’s perfect for when a base layer alone is not enough, but insulation would make you overheat. Weighing under 47g this is a must-have item for when you plan to hike in cool weather. Elastic at the back hem, and at the wrists to keep wind out. Elastic at the hood for a snug fit around your face. Constructed from .51 oz/sqyd Ventum ripstop nylon. This fabric is tightly woven and heat calendared to cut the wind.
