Quick verdict

This is a Gamma-series Arc'teryx softshell listed in black, hidden gray, and cool gray, sizes S–3XL. Sourced reviews describe the Gamma MX model as trim-fitting, stretchy, and wind-resistant with taped seams and DWR. Independent buyer reports cover that model rather than this listing, so confirm sizing and return terms with your agent first.
