WARMTH THAT FITS UNDER A HELMET Castelli's original Difesa cap is a Windstopper piece that's best for extreme conditions. With the Difesa Thermal they removed the windproofing, but by doing so dramatically improved moisture management, so it's best for cool to cold conditions, especially with high-intensity riding. They placed a rib-knit wool wrap around the ears to keep you warm but keep it all relatively thin to fit under a helmet. - Thermoflex Core2 fabric on body of cap for warmth and optimal wicking to move moisture away from your skin - Wool-blend ear cover - Classic fit with vintage appeal

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

• Wicking layer to keep sweat out of your eyes • Mesh top panel for ventilation • Fits under helmet

Made for warmth with excellent wicking while minimizing bulk under your helmet. This simple helmet liner has a raw-cut edge so it doesn't interfere with the straps or helmet cage, while the Thermoflex fabric is surprisingly warm and wicks away moisture. - Thermoflex is warm, soft and stretchy - Flat-lock stitching - Contoured to cover ears - Raw-cut edge lies flat and doesn't bunch under helmet - Reflective detailing on back

- UPF 50+ - Classic Castelli fit and comfort - One size fits all

If there's one failing of most warmers it's that they absorb water like a sponge. On rainy days they end up waterlogged and providing compromised warmth. The Castelli Nanoflex Armwarmers are perfect for riding in conditions that are both cold and wet. Nanoflex is a proprietary Castelli fabric. They begin with with their super-warm and ultra-stretchy Thermoflex fabric, used in many of their winter garments, and then coat the outside with ultra-tiny nanofilaments that cause raindrops to run off the fabric without soaking through. Despite its water-resistant finish, Nanoflex fabric remains highly breathable, keeping you comfortable in almost any conditions. - Water -resistant Nanoflex fabric - Same breathability , stretch, and warmth as their standard - Thermoflex warmers - Double-sided Silicone grippers keep the warmers in place - Great in every possible condition
