Just as the name says, the Castelli Emergency 2 Rain Jacket is the go-to for emergency rain protection. Castelli has made the jacket completely waterproof with a 10,000mm water column rating. It is compact enough to take up only half a jersey pocket, so you can stash it away with ease and it wont take up too much cargo room. The jacket has a slight stretch and has a superb on-bike fit with enough room to still fit over a Gabba or any thicker winter jacket. The Emergency 2 has all the trappings. A waterproof zipper seals out the rain, a long tail provides extra coverage, the wrist closures fit over gloves, and the 360 reflectivity makes this an ideal friend on dark country lanes or when commuting through the city. The only compromise Castelli has made with this jacket is it is less breathable than its topflight rain jackets. The reason? Simply to make this jacket more affordable. Available in a mute military green for those seeking an understated look or high vis orange for some welcome visibility.
