Perfetto Light RoS Jersey

Wind protection on gusty spring rides shouldn't have to ad weight to your kit, and Castelli aims to mitigate the weight penalties with the Perfetto Light RoS Jersey. This jersey takes the mark as Castelli's lightest short-sleeve jersey with wind protection ever, thanks in part to its featherweight GORE-TEX Infinium 203 Stretch panels that make up the bulk of the core, and the sleeves. This lightweight fabric acts as a barrier against wind and all-but the nastiest of downpours, while still maintaining GORE-TEX's signature breathability through it all. On the back, Castelli employs its Nano Flex Light Woven fabric that ads extra breathability and stretch, all the while providing coverage from wheel spray and showers.


  • Castelli sheds weight in the wind with this lightweight jersey
  • Jersey scales in at just 172g as Castelli's lightest wind jersey

Phenomenal jersey!

I've used it once or twice and have initial impressions

I never thought I would ever spend this much for a jersey, because, honestly, I find it crazy. However, this is one truly phenomenal jersey! Those front panels will protect from any wind and it zips nice and high. One of a kind and very versatile jersey, the perfect piece of clothing every cyclist would definitely love in their closet. I would love to have a few, but the price forbids me...

Windproof perfection!

I've used it once or twice and have initial impressions

Unlike many windproof or 3 season bike jackets, this is very thin. This makes it by far the most useful and versatile jersey/jacket around. In cold weather, add a thick baselayer/thermal jersey, and windproof armwarmers and you are set for some pretty cold weather. At the same time, there are many rides where it is only the wind that is making you cold, whether blowing or from riding. This completely blocks the wind in the front, without adding any warmth. This way, once you are out of the wind, or slow down, you don’t overheat like you do with a heavier, garment. It also means you can wear a warmer layer underneath, so if you need to unzip, you don’t go from boiling to freezing. The other key part is the thin, and water repellant, fabric on the back. Too many windproof jerseys are way to warm in the back. Bike jerseys/jackets need to be warmer in the front than in the back, regardless of the absolute amount of warmth the provide. Keeping the back thin matches well with the front, so you can add warmer layers underneath if needed, without your back getting to hot. The sizing on this women’s one runs slightly large, quite unusual compared to their mens line. Saying that, it is a performance road bike fit, so when I say that, I mean it in terms of trying to get a very snug, no flapping fit. If that is what you are after, I would not size up from the sizing chart. The length is quite long too, so if you are shorter, it will be too long in the front if you upsize. The tightest parts, and the only reason I chose M instead of S, was sleeve tightness.
