HELIOS Heated Coat Reviews: - The Helios heated coat features 4 independent heating panels with versatile control - The panels can be controlled front and back or in isolated sections with the click of a button - The coat is designed with a detachable hood, front pockets, covered zipper, and adjustable Velcro closure around the wrists - It has an inside zipper pocket with a built-in USB port for storing and charging a power bank (not included) - The coat is not the warmest parka tested, but is best used for ice or alpine belay or backcountry trips where you will be moving most of the time - It has 7.9 oz. of 850 fill down, comparable in warmth to other light parkas such as the Rab Infinity and Outdoor Research Incandescent - Made with high-quality 850 fill down and a light but weather-resistant outer fabric - Weighs 16 oz., making it one of the lightest down parkas tested - Designed for technical or active use such as climbing, mountaineering, and ski touring - Good warmth-to-weight ratio - Minimal features to save weight and increase packability - No Velcro cuffs, only simple elastic piping - Waist does not have adjustability, only elastic piping - Hand-warming pockets have a "clamshell" design without zippers - Pockets lined with down on both sides - Small zippered inner chest pocket for small items - Hood has front adjustability with two cinch cords - Jacket does not offer a lot of face protection in windy and snowy conditions - Short fit, appreciated by climbers as it stays out of the way and is easy to access gear when used as a belay parka - Short fit means less warmth and the jacket rides up annoyingly when worn outside of climbing situations - Size large adds an inch to the length, buyers may consider purchasing a size up - Features Pertex Endurance outer fabric, which is weather-resistant but not as protective as heavier parkas in very windy and snowy weather - Relatively durable but designed to be lightweight, other parkas available with stronger fabrics for increased durability - Minimal features such as waist cinches, cuff Velcro, and pocket zippers - Best used for climbing belay or fast and light backcountry activities - Price of the Hooded Helios is $389 - If looking for a more versatile parka, consider the Patagonia Fitz Roy Parka or the Rab Neutrino Endurance.
