Size...L Color...Black Arc'teryx ARC'TERYX This is a successor to the Atom AR and Atom Heavyweight. The Coreloft in the sleeves has been increased, improving heat retention, but it's more mobile than the Atom AR. After purchasing new, I only tried it on once indoors. I'm selling it because the size doesn't fit. ARC'TERYX Atom SV Hoody Men's. The previous Atom Heavyweight Hoody Men's has been updated, and the name has been changed to Atom SV Jacket. The warmest in the Atom series, this mid-layer jacket is lightweight and looks smart without being bulky. It is breathable, wind-resistant, and water-resistant, and the Coreloft synthetic insulation used in the lining maintains its loft even after repeated compression and storage, making it convenient to carry and transport. The Tyono 30 shell on the surface is treated for durability and is designed to handle various active scenes such as sports and outdoor activities. The hand pockets on the left and right and the inner chest pocket have zippers, and the hem has a drawcord for adjusting the fit. The regular fit is moderately roomy yet has a sleek silhouette, making it easy to incorporate into everyday styling and perfect for urban use. The insulated, helmet-compatible hood with a drawcord adjuster allows you to confidently handle sudden changes in weather during commuting or touring.
