Our proprietary Vapor Wool fabric is a lightweight and ultra-fast drying tri-blend. The Vapor Snorkel Hood has an athletic fit, making it the perfect piece for a day that transitions from mountain to town. The semi-fitted hood adds extra protection from wind without bulk and makes it a must-have piece for life on the go. Wool is anti-microbial, so there is no odor, and this heathered year-round fabric has natural stretch. Our Rambouillet-Merino wool is 100% grown in Montana and the custom blended yarn is knit and garment sewn entirely in the USA.
