Whether there's a sudden drop in temperature or you find the temperature vastly different at the resort's peak compared to its base area, rely on the versatility and warmth of the Columbia Men's Electro Amp Core Vest. Designed with Omni-Heat Electric technology, the Electro Amp Core Vest provides continuous heat at the touch of a button. There are three heat settings: red for high, yellow for medium, and green for low. With one charge of the lithium ion batteries, the Electro Amp Core provides up to two to four hours of continuous heat to your core in even the coldest conditions. To boost the warming power and to provide a bit of heat even when you don't have the electricity running, Columbia gave the Electro Amp Core Vest Omni-Heat a thermal reflective lining which helps regulate your temperature by reflecting and retaining the warmth your body generates while dissipating moisture and excess heat to keep you comfortable. In addition, there's 100g Omni-Heat insulation throughout for cozy warmth and comfort. Whether you're walking around the mountain village, spring skiing, or running errands, you can also count on the Electro Amp Core's Omni-Shield rain and stain barrier to protect your from light rain and spilled coffee. Its active fit ensures unrestricted mobility while you ski, snowmobile, or walk around town, while the Electro Amp Core's internal pocket and two hand-warmer pockets house your cell, wallet, or other small essentials.
