Pazzo means 'crazy' in Italian, perhaps a fitting adjective for someone looking for a garment that can provide true 3-season versatility. Too often jackets with removable sleeves are developed as jackets, with the vest just an afterthought. That's not the case with the Castelli Pazzo Jacket. It's equally great as a vest or as a jacket, and it will quickly become a favorite addition to your wardrobe because of this versatility.
The Pazzo Jacket features Castelli's new SG0.6 Wind fabric with a light brushing on the inside surface for better insulation and a membrane on the outside for enhanced performance in wet weather. But rather than just use one layer of SG0.6 fabric, Castelli uses two. Why? Two layers of fabric enables Castelli to sandwich a windproof membrane in between to trap air in the fibers, thus providing excellent insulation. It does this without sacrificing the potential for moisture movement out of the jacket to help you stay warm and dry. Sounds crazy, right? Well, it works.
The Pazzo comes with a full camlock zipper that stays flat when the zipper head is down. Three rear pockets are spacious enough to hold spare tubes, gloves, and food, while two rear reflective tabs offer increased visibility in low light conditions.
The Castelli Pazzo Jacket is available in three color combinations -- Black, Red/white, and White/black. It comes in six Castelli-specific sizes from Small through XXX-Large. Like most Castelli clothing, the Pazzo is designed to be form-fitting as the technical fabrics used to construct the jacket work best when in close contact with your body. Be sure to check the sizing chart to ensure proper fit.
I've used this jacket a handful of time this past fall in temps ranging from 35-50 degrees F. The zipp off sleeves are a nice feature, however wind does seep through the overlapping layers. It is fairly wind resistant, but it is not at the level of a Windstopper garment. As for warmth, I tend to layer, so I can't say how this would feel with just a baselayer on. I bought an XL as I am 6 ft. 1 in. and 180 pounds. A large would fit a bit better and bee more aero, but the little extra room allows for the layers.
