A heavy baselayer for the chilliest days on the mountain, the Burton Women's Expedition 1/4-Zip Top is built to keep you shredding when other baselayers have run to the lodge. Made of DryRide Ultrawick Expedition weight fabric, this top is not only warm, but it's also supremely breathable and has moisture-wicking properties. After all, even when your nose is cold, if you're out riding all day, you're going to sweat. Knowing this, DryRide pulls moisture away from your skin to keep you dry. Additionally, it was given an antimicrobial finish that will stave off the odor after a full day of powder. The baselayer is cut extra-long, which keeps it tucked into your pants. The collar is finished with a chafe-free chin guard. So, you'll stay out long after your sweatpants-wearing friends have settled indoors by the fire. And, more importantly, you'll look great once the sun sets and your jacket comes off.
For heavyweight, low-bulk warmth on the mountain, pull on the Burton Expedition Zip Top for women. This quick-drying, highly breathable performance layer features 4-way stretch DRYRIDE Ultrawick fabric with an anti-microbial finish to keep you fresh when you're working up a sweat. The soft-lock seams eliminate over-lapping fabrics for a smooth, chafe-free fit, and the extra soft, fleece chin guard protects your neck and chin from wind and cold, keeping you comfortable all day as you ride.
