Packable jackets earn their keep through a simple calculation: how much protection do you get versus how much space do you sacrifice? The Castelli Squadra Stretch Jacket tips this equation heavily in favor of carrying it, compressing into a jersey pocket while delivering genuine wind and water resistance when conditions deteriorate mid-ride.

Full-length zipper ventilation lets you dump heat on climbs while keeping wind protection on tap for descents.

The stretch fabric accommodates layering a vest underneath on genuinely cold days while still packing down when conditions warm up. Four colorways give you options from high-visibility Electric Lime to understated Light Black.
