<p>Hyper-light and totally waterproof, the Idro Jacket raises the bar for a high-performance cycling shell. You can stuff it into an already packed jersey pocket, and it weighs in at 89 grams (lighter than any smartphone). The miracle is the game-changing fabric that puts the super breathable membrane on the outside. The unique system means the fabric won't absorb moisture and doesn't require DWR treating, yet it's still incredibly breathable.</p><ul><li>GORE-TEX® Active Shakedry 2-layer fabric has an external membrane for breathability, waterproofing and weight reduction</li><li>Fully taped seams</li><li>Full-length water-resistant YKK Vislon zipper</li><li>Anatomic, shaped cuffs and hem with low-profile elastic binding for a secure fit</li><li>Reflective elements for low-light visibility</li><li>Streamlined, slim fit is optimized for the ride position</li><li>Castelli recommends this jacket for temperatures between 6 and 20°C</li></ul>

Castelli Idro Jacket - Women's

Waterproof garments use waterproof-breathable technologies and are fully seam-taped. Water-resistant garments use waterproof-breathable technologies but their seams are not taped. Water-resistant garments repel water and protect against wind but are not made of waterproof fabric.

A windproof garment does not allow any air to permeate the fabric.  A garment with windproof panels has panels of fabric that are totally windproof, but the rest of the garment may not be windproof.  A wind-resistant garment resists some wind, but not as much as a garment that is windproof.

Usually referred to as DWR. A treatment made to fabrics that causes water to bead and run off instead of soaking through.
