Although the RoS in the name signifies Rain or Shine, Castelli points out that the emphasis should be on dry–weather comfort, which is where this jersey really excels. When you also get near waterproof protection, it should be no problem if you do get caught in the rain. Castelli worked with Gore to develop two new Castelli exclusive GORE–TEX INFINIUM™ WINDSTOPPER® fabrics. A light fleece–lined water–resistant version is used on the forward–facing surfaces and a lighter, stretchier fabric is used on the back that maintains the breathability of the previous fabric while improving water repellency at the same time. Coming in at a near ideal weight, the Perfetto doesn’t utilize built–in insulation so you can layer over a light base layer for moderate conditions. Or you can add a thermal jersey underneath and take it to very cold conditions. You decide.

The Perfetto family features are all there: excellent fit, easy–sliding YKK® zipper, long tail to protect from wheel spray, reflective panel on the back, and discreet styling that belies the jersey’s racing pedigree. This is the one jersey that belongs in every cyclist's quiver.

Works well in hard rain
by jdromick

I bought this jacket (not a jersey) for winter riding (rain and cool/cold conditions). Today, it got tested. Hard rain at 45F and 15-20 mph wind. I was comfortable and stayed pretty dry. I am 6' and 172 lbs and I bought the 2x so that I could wear a couple of layers beneath it for cold conditions. I normally wear a L size Castelli jersey. This fits pretty snuggly, so when in doubt go at least one size larger. The rear pockets are large and useful. The fluorescent green is particularly useful for poor lighting conditions.

Love my Castelli Perfetto LSJ! Wear it whenever temps dip below 45-50F. Sleek, comfortable and warm.

Don't go by their size chart. They fit very tight and very small. I started with a Men's Medium to be on the safe side and ended up with a Men's XL. Now wish I had ordered an XXL. I am 5' 8 and weigh 150 lbs - the sizes are way off, but you'll love it when you get one that fits.

Good cool weather upper

This is a very nice garment. The look is very good and the feel is nice. It keeps you warm. The one big concern for me is the sizing. This must be a Castelli brand issue. Their sizing definitely does not fit the description. I am a 44 chest which should be an extra large. But for this jersey I would need like a double extra large to be comfortable. Castelli XL is like a medium so definitely go a size larger when ordering.

Great lightweightstylish race jacketjersey that fits snugly

Nice jacket, with thin technical fabric that is soft and stretches. I haven't ridden it yet but it feels like it will block the wind and light rain very well. Some have warned you need to size up twice from your normal jersey size due to the snug fit in the arms, chest, and shoulders(especially if you intend to wear a thermal base layer).

I bought an XL, whereas the sizing from Castelli indicated a large might be right(40 chest is between L and XL). The XL fits me with my Nike baselayers, however, it is a very snug, race fit. All the other dimensions for a Large fit me fine, except I thought the neck might be a little loose.

Since I plan to use the jacket more for group rides and training rides, I'm considering going with the 2XL instead of XL to give me more room for layering, and a less aggressive fit.

These are my measurements

Chest - 40

Waist - 32.5

Hip - 35.5

Neck 15.5

Biceps - 11.5 - 12.5

Height - 5' 11

Weight - 160 lbs
