This is the Arc'teryx Atom Heavyweight Hoody. It's the 2023AW model after the minor change, equivalent to the Atom AR Hoody before the minor change, and the current Atom SV Hoody. The color is the popular black, and the size is men's XS. (It's an overseas size, so it's about a Japanese size S, with actual measurements of 66cm length, 53cm width, 46.5cm shoulder width, and 63cm sleeve length.) This was purchased through a lottery from the Arc'teryx official store in January 2024 and has only been worn for a short time 3-4 times, so it's in excellent condition with almost no scratches or stains. However, please understand that this is a used item. The current retail price is 59,400 yen, so take this opportunity. The following is the description: Product Description The warmest in the Atom series, this piece functions as a standalone or mid-layer. Atom Series: Synthetic high-insulation mid-layer. *The Atom Heavyweight Hoody has changed its name from the Atom AR Hoody. Warm, breathable, windproof, and weather-resistant, this is a foldable and durable piece. The Atom Heavyweight Hoody, which can be worn as a mid-layer in cold regions or even on its own during rest, is one of Arc'teryx's most versatile high-insulation items. The Coreloft synthetic insulation provides efficient warmth and is also resilient. The lightweight, windproof, and water-repellent Tyono 30 shell has been treated for durability, and the Permeair panels under the arms improve ventilation. The helmet-compatible, high-insulation hood provides even more warmth and protection.
