The EQUIPE RS Thermo Rain Jacket S11 wraps a Nimbus 3-layer softshell rated past a 25,000mm water column around a breathability figure of 29,900 grams per square meter every 24 hours, so heavy rain stays out while sweat still gets a way through. Four-way stretch keeps the fabric moving through a hard effort instead of restricting it, and a double-slider zipper opens from either end for quick venting or pocket access without breaking stride. An aero, second-skin fit mirrors the race layers worn underneath, so the jacket adds protection without adding drag. What Our Gearhead(R) Experts Are Saying:"I rode through a genuine downpour at tempo and never felt that clammy buildup I expect from a fully waterproof shell. The Nimbus softshell is doing both jobs at once, not trading one for the other."
