Castelli RoS Shoecover
$99.99
The Rain or Shine concept within the Castelli collection is a designation for products that are designed to excel in dry weather yet provide significant water protection when you get caught in the rain. This Rain or Shine shoecover is made with a stretch water-resistant and windproof breathable fabric with a fleece liner and is cut high to the base of the calf muscle for warmth in dry weather. For rainy conditions, we've moved critical seams toward the outside, where they're less exposed. The zipper is also moved to the side, and we've included a molded reflective heel cup for visibility. - Rain or Shine product made to excel in both dry and wet conditions - Contoured seams offer optimal fit around the ankle - Internal gripper around cuff edge to seal out water - Water-resistant inner splash zone with engineered seams to limit exposure to water - Reflective heel cap for maximum visibility - Textured grip pull at back heel for easy on

Made using a brushed, bi-elastic techno fabric made of hollow microfilaments which boost its insulating power, also featuring anti-bacterial properties.

Castelli Pioggia 3 Shoecover
$59.99
We call it the Pioggia shoe cover, and although the name is Italian for rain, that doesn’t really capture the essence of this bootie. Sure, it’s completely waterproof, with sealed seams, a waterproof zipper, and a silicone-sealed top edge to keep water from entering. We’ve backed the PU-coated fabric with fleece to make this bootie warm in the coldest conditions, while the high stretch also gives it a close, comfortable and aero fit. - Waterproof PU-coated stretch fabric with fleece layer inside - Silicone bead at inside top of cuff to seal water out - Wrap cuff construction to optimize fit  - Waterproof zipper  - High-durability material under foot
Castelli RoS Cycling Cap
$34.99
Over-Engineered Simplicity We wanted to make a cycling cap that's great in dry weather yet can protect in case of rain. The trick is a patented system in which the windproof, water-repellent front panel can fold back for complete breathability or fold forward to protect. Better yet, you have three ways to wear it: with the protective panel folded back, moderate breathability with the cap turned around backward, or full close. The Pertex fabric is ridiculously thin to fit under the helmet, yet has enough air permeability to prevent you from wetting out as you would under a non-breathable cap. - Rain or Shine product made to excel in both dry and wet conditions - Patented convertible front panel can close for wet conditions and open for extra ventilation in warmer conditions - Pertex Quantum base fabric with low air permeability to let sweat escape, while the DWR coating keeps light rain at bay - Extra thin and lightweight to fit under your helmet
