FAQ

How does RoS fabric differ from standard waterproof cycling fabrics?

RoS (Rain or Shine) fabric is engineered specifically for high-output cycling. Standard waterproof membranes trap heat and moisture during sustained effort. RoS allows significantly more vapor transmission so you stay dry from both sides.

How do I remove the sleeves on the convertible version?

The sleeves zip off cleanly, converting the jacket to a vest in under a minute. The zipper seam sits at the shoulder seam and does not create bulk or gaps in the waterproof construction when connected.

Is the Perfetto RoS worth the price over a cheaper rain jacket?

For casual riders, a less expensive option may suffice. For cyclists who train consistently through variable weather and want to avoid overheating or soaking through from the inside, the Perfetto RoS justifies the investment over multiple seasons.

Best For

Serious road and gravel cyclists who train in variable weather year-round and want a single high-performance jacket that handles everything from cold dry mornings to sustained rain.
