Fjallraven says about the S-F Adventure Vest
Light and packable vest, optimized for bike riding with a reinforced upper torso providing wind-resistance where it’s most needed. This section is also waxable for even higher wind- and water-resistance. The back and lower front are made from light and durable recycled polyester. High-low hem, with elasticated back and armholes for a closer fit when riding. Several functional pockets including two top-loaded pockets and two zippered hand pockets. Can be packed into its own pocket. Great as backup gear on any bike ride. Part of the Fjällräven/Specialized series for urban rides and bikepacking adventures.
