Authentic product. It sold out quickly due to its popular color. I purchased it from the Arcteryx online shop. I bought it last year and wore it only a few times during one season, so I think the condition is very good. However, please understand that it is a used item before purchasing. The color is 24fw limited RUNE, a very luxurious beige. I loved it very much, but I am selling it because I don't use it often. A lightweight and warm down jacket. It can be used as an alpine mid-layer, as well as on its own in a wide range of situations. The Cerium Jacket has been renamed from the Cerium LT Jacket. The Cerium, which has a proven track record in a wide range of alpine missions and backcountry adventures, is compact, lightweight, and provides exceptional warmth. The updated design, aiming for optimal fit and performance, utilizes more environmentally friendly materials while maintaining the same outstanding lightweight warmth performance as before. In addition to 850-fill responsible down, Coreloft synthetic material is placed in areas prone to moisture. This provides high-quality insulation performance. The surface material made of recycled 15-denier Arato™ nylon is lightweight and durable, with a bio-based liner that reduces the use of petroleum. The clean design incorporates a three-dimensional structure for ease of movement. Stains, tears, odors, etc.: None Material (filling): Down Material: Nylon Color: Beige系 (beige-based)
