Just like the name says, Castelli wanted to create the ideal simple emergency rain jacket. They made it completely waterproof and compact, and, as you’d expect from Castelli, they also gave it an amazing on-bike fit, yet it’s still roomy enough to fit over a Gabba. This jacket is an emergency piece, so Castelli knew you wouldn’t want to break the bank with it, but the only real compromise compared to the top-of-the-line offerings is in breathability. They didn’t make this for an all-day rain ride, but it’s just right for your next emergency.Key Features:Deluge Light 2.5-layer waterproof fabric keeps rain off with 10,000mm water column.Slight amount of stretch for excellent fit in riding position.Folds into half a jersey pocket for emergency situations.Innovative “gutters” drain water away from hands and off back.Waterproof zipper and seam sealing keep all water out .
