Next-generation breathability in a stretch short-sleeve jacket that blurs the line between a jersey and a jacket, for cool to mild conditions

Exclusive Castelli Ristretto technology with engineered air permeability keeps most wind out, allowing in just enough to provide exceptional breathability — 12 times more than previous Castelli Gabba jackets

Close-to-body stretch fit doesn’t feel constricting, thanks to Ristretto stretch fabrics

Minimalist construction for speed and comfort

YKK® Vislon® zipper for easy sliding

3 rear pockets

Reflective piping at bottom of pocket for visibility

Castelli partnered with fabric innovator ITTTAI® to create an exclusive fabric, combining advanced stretch, breathability, and water protection through ITTTAI®’s membrane and lamination expertise
