There's no need to head for the lodge when the temperature drops, not when we're wrapped in the Sarah Insulated Jacket from Flylow. With a slim layer of synthetic insulation to trap your body heat, this jacket ensures you stay so warm and toasty that you can explore the mountain until the chairs stop spinning. The two-layer stretch fabric comfortably moves with you, whether you're adjusting your boot buckles or leaning into a pole plant on the steeps, and it's also fully waterproof and impressively breathable to block moisture from the outside and protect you from being soaked by your own sweat. Plus, we really love that if you start to overheat, you can take advantage of the large underarm vents, and utilize the multiple pockets to store your favorite snacks and other on-mountain essentials.
