When ominous weather looms over race day, we often see the pros requesting a modified water bottle that's been stuffed with a lightweight jacket. Mechanics simply cut a bottle's top off and drop it in the seat tube cage, providing convenient and effective storage for riders to quickly access additional layers, nutrition, and rain shells. For the Garmin-Barracuda riders choosing this option, chances are that team mechanics are outfitting those bottles with Castelli's Sottile Due Jackets.
The Sottile Due Jacket is Castelli's new lightweight barrier against the elements. It's light enough to wad up and stuff in your jersey pocket or bottle without adding any noticeable weight or bulk to your kit. The jacket is constructed from a blend of Castelli's breathable, water-, and wind-resistant fabrics, with mesh at the underarms for added breathability. The body panels of the Sottile Due are semi-transparent, so your team kit and race number stay visible through the gloomiest of weather. Designers at Castelli kept the fit of the jacket fairly trim and body-forming. This is to keep weight to a minimum and to avoid the 'garbage bag' effect caused by many ill-fitting shells. Sleeves are long to accommodate the cycling position, with a generous drop-hem to further cover your backside.
The Sottile was created with a minimal design, but the small and important details were given proper consideration. A full-length contrasting front zipper aids in both temperature regulation and on-the-bike removal. Rounded elastic banding at the cuffs and hem keep the jacket in place, a single side zipper provides access to your jersey's pockets underneath, and small reflective elements increase your visibility in low-light conditions.
The Castelli Sottile Due Jacket is available in six sizes from Small to XXX-Large and in the colors Transparent White and Yellow Fluo.
