The go-to jacket for rain protection, whether for all-day use or emergency use, since it easily stashes away in a jersey pocket. With discreet styling and 360° reflectivity, it can do double duty as a commute jacket.
- Deluge Light 2.5-layer waterproof fabric keeps rain off with 10,000 mm water column
- Slight amount of stretch for excellent fit in riding position
- Folds into half a jersey pocket for emergency situations
- Stuff pocket integrated into mesh vent at top of back
- Waterproof zipper and contrast seam sealing keep water out
- 360° reflectivity
Just like the name says, we wanted to create the ideal simple emergency rain jacket. We made it completely waterproof and compact, and, as you’d expect from Castelli, we also gave it an amazing on-bike fit, yet it’s still roomy enough to fit over a Gabba.
It has all the trappings of a performance rain jacket, with the waterproof zipper, long tail, long sleeves, and wrist closures that can go over gloves, yet we knew you wouldn’t want to break the bank with it, so the only real compromise compared to our top-of-the-line offerings is in breathability.
We kept the styling toned down and added a bright colorway in Brillian Pink so that you can easily use this as a commute jacket and still look great when you get to the office. If you're going to wear it over office attire you may want to go up one size.

How to Measure
- Chest: measure horizontally under the arms around the fullest part of the chest.
- Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
- Hips: measure horizontally around the fullest part of the hips with feet together.
- Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
- Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.
- Bra: measure bust at the fullest point and underbust directly below the bust.
Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
