Whether trying to stay warm during a day at the resort or on a chilly night at the campsite, the Mountain Hardwear Butter Mockneck Top is our go-to for comfortable warmth. The brushed jersey knit body fabric keeps us warm and features anti-odor and moisture-wicking properties to keep us feeling and smelling fresh during high-output activities. The slim fit allows for easy layering on colder days, and low-profile thumbholes keep the sleeves from riding up.
