What Our Gearhead® Experts Are Saying: “This jacket lives in my pack on big days. It’s incredibly light, packs down tiny, and the waterproof panels on the hood and shoulders are clutch when snow starts falling or ice is melting overhead. It’s warm enough for stops but breathable enough that I’m not racing to take it off.” We bring the Helium Down Hooded Jacket on every mission where weight, warmth, and protection all matter. Designed by Outdoor Research for demanding alpine pursuits, this jacket gives us reliable insulation without slowing us down. Whether we’re ice climbing, touring deep in the backcountry, or managing long transitions in cold conditions, it’s always ready when we need it. High-loft down delivers exceptional warmth for its weight, while reinforced waterproof panels in high-exposure areas help fend off dripping ice and surprise snow showers. The jacket packs into its own pocket and clips easily to a harness or pack, making it effortless to carry until conditions call for it. With smart details like a soft-lined pocket and adjustable cuffs and hem, this layer proves that serious warmth doesn’t have to come with extra bulk.
