The Vista Crewneck Top layers on in a stretchy microfleece built to move through sub-zero days without binding. Thumbholes keep the sleeves in place under an outer layer, and finished seams hold up to repeated wear without chafing. Moisture-wicking fabric and odor-resistant treatment keep it fresh through long days outside. What Our Gearhead(R) Experts Are Saying:"I've worn this from the first chairlift to the last run without ever feeling clammy or cold. It regulates heat on its own, so I stop thinking about layering once it's on."
