Castelli‘s Sottile Due Vest is the lightest, most packable vest in its 2013 lineup. At around 64 grams, its the race-weight vest that you can easily retrieve from your rear pocket the moment that youre confronted with either light rain or a long descent.
The Sottile Due Vest is made from a semi-transparent, slightly stretchable fabric that is rated at 10,000 mm of waterproofness, is wind-resistant, and is highly breathable. And in case youre wondering, this rating means that a 10,000mm fabric will repel a column of water up to 10,000mm in height, or about 32 feet. In more relatable terms, this vest provides nearly the same waterproofness as a typical pair of ski pants.
In terms of fit, the Sottile Due has a sleek, race-inspired cut with both an extended collar down and a wheel-spray-deflecting elongated rear. The narrow arm openings will virtually eliminate crosswind drafts from sneaking in, and it has a generously sized single-zip on the right side that provides easy access to your jersey pockets. Accordingly, the days of fussing with your vest to reach your rear pockets are over.
For an increased visibility to motorists in low-light conditions, Castelli has also added reflective elements throughout the vest.
The Castelli Sottile Due Vest is available in six sizes from Small to XXX-Large and in the colors Yellow Fluo and Transparent. Please note that Castelli estimates a useful temperature range of about 50 to 64 degrees Fahrenheit for this vest.
