Excelling in dry weather, but with extra protection when it turns wet, the Castelli ROS Cycling Cap brings the classic cap bang up to date. The ROS Cycling Cap adaptability comes from a patented system that sees the windproof and water-repellent front fold back for incredible breathability or pulled forward for weather protection. In effect, you have three hats in one - with the panel folded back, a highly breathable cycling cap - worn peak to the back for a balance of breathability and protection - and fully closed for the worst of weather conditions. The Pertex® fabric is also ridiculously thin to fit under a 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

AngeloGreat hat little tight
Mr BaxterGreat for velo bald warriors.
RonanBought to stop my head getting sunburn. Was out for 4 hours in 26 degrees sunshine over the weekend and it did the job. Still keeps you cool and keeps the sweat from your eyes. Have yet to use it in the rain.
Mr KayeFab cap. Good fit no pinching. Light weight with the roll back front section allowing more air through the cap is a real bonus. Good cover in all weather.
Mr McCraeTheme from previous reviews is that it is great hat for bald men! As a bald man I agree, I can wear it under my helmet and it is light and comfortable. It can keep me dry and relatively warm on wet colder days (when the movable fabric is pulled forward) and will keep me cool and keep the bugs off my head on warm/dry days, when I pull the fabric back. A hat for a variable day of Scottish weather👍
MichaelGreat under helmet cap for keeping the cold out
Mr DowGreat cap, for under my helmet,, keeps rain off my head, being bald, and peak keeps it off glasses
