The Castelli Perfetto Light is an exceptionally good short-sleeve jersey that offers windproofing and water resistance in a lightweight package. It's a lot like Castelli's genre-defining Gabba but slightly dialled back; a little less hardcore, and a bit more breathable.
Chances are that if you've been road riding for a while you'll know about Castelli's Gabba, right? In short, it's a windproof, highly water-resistant, and breathable jersey in a performance cut, and it has set the standards in that market over the past five years. (Bloody hell! Five years!) You can check out our review of the Castelli Gabba 2 jersey here.
The Perfetto Light follows a similar concept but it's not quite as windproof or as waterproof. It is more breathable, though, and a lighter weight, so it's suitable for warmer conditions.
'What makes the difference between the Perfetto Light and the Gabba?' you ask.
Okay, keep your wig on, I was getting to that.
Like the Gabba, the Perfetto Light uses a Gore Windstopper fabric, but whereas the Gabba uses Windstopper X-Lite Plus, it's Windstopper 150 for the Perfetto Light. Although not as stretchy lengthwise, Windstopper 150 is very stretchy across its width and is also about 25 per cent lighter.
This Windstopper 150 is used for the front panels, the collar, the yoke, the tops of the arms and the tail. Or, to make things easier, it's the blue stuff in our pictures! It's a softshell fabric that, as the name tells you, stops air getting through, and it's also very water-resistant.
Whereas the Gabba is made from Windstopper almost throughout, the rear panels and the underside of the Perfetto Light's arms are made from Nano Light Pro fabric.
Give me a chance, will ya? It's like the Nano Flex that Castelli uses for some tights and arm warmers, but without the brushed back. And Nano Flex, before you ask, is a warm polyamide/elastane mix that's given a coating of silicone 'nanofilaments' to make water roll off the surface rather than soaking in. (Check out our review of the Nanoflex Pro Bibtights here.)
Pull the Perfetto Light on and the cut is that of a slim-fitting race jersey. As I mentioned, the Windstopper 150 fabric (the blue stuff) doesn't feel quite as stretchy as Windstopper X-Lite Plus but, on the other hand, the Nano Light Pro is considerably more stretchy, so chances are you'll get a close fit without anything feeling too tight.
Head out into the big wide world and the Perfetto Light immediately impresses. The Windstopper 150 just doesn't let cold air through but it does allow sweaty vapour to get out well, and the Nano Light Pro fabric is as breathable as a pair of Roubaix tights, say, or thick bib shorts. There's no membrane in there to hinder the escape of damp air.
This, along with the fact that it's fairly lightweight, means the Perfetto is suitable for quite warm weather. I've used it with arm warmers in temperatures from about 11°C right up to 18°C and been perfectly comfortable (I do seem to run cold compared to most other people). It might be good for a couple of degrees warmer but we've not had the weather to check that yet. That temperature range covers most of the UK spring and autumn, plus a lot of early mornings and late evenings in the summer, so you're certain to get your money's worth here.
Talking of which, the Perfetto Light is a little cheaper than the Gabba (£140), and a fiver less than the Endura FS260-Pro SL Classics Jersey, which Mike was very impressed with (though you do get arm warmers for your £129.99). Jez also rated the Stolen Goat Orkaan very highly, and that's priced at £108. Santini's Beta Windstopper Short Sleeve jersey, reviewed on road.cc back in November, is lightweight and cheaper than the Perfetto Light at £109.99, although Stu was a little critical of the fit.
Although water repellent, the Nano Light Pro panels don't keep out the rain as well as a Windstopper fabric, so the Perfetto Light isn't as weather-proof as the Gabba. On the other hand, it's still pretty impressive, and teamed up with some water repellent arm warmers it can see off road spray and the worst of a short shower.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Castelli says, "It was the pros who first asked for a Gabba that's not as hot as the Gabba but warmer than the Fawesome Vest. So we started from the Gabba and made the back in Nano Light fabric – the same fabric as our Nano Flex tights but without the brushed fleece inside. This gives the piece a lot of breathability and keeps you from overheating inside. We further lightened it up by using a lighter weight of Windstopper (a full 25% lighter than the one used on the Gabba) on the front.
"You make think that this is filling a very small niche. But just try it. It can cover most of the conditions of the Gabba (except wet racing and very cold), yet it handles warmer temperatures better. And the fit is exceptional, which is one more reason you'll keep reaching for it. The consensus of our Castelli test crew is that this piece doesn't fully replace the Gabba or Fawesome, but it's another arrow in your quiver that is ideally suited to cool temperatures, especially when it's dry or there's a risk of light rain."
Tell us some more about the technical aspects of the product?
Castelli lists these features:
* Gore Windstopper 150 fabric on front, sleeves and yoke for lightweight wind protection
* Nano Light fabric on the back sheds water but allows significant breathability
* 3 external rear pockets
* Long tail with reflective trim
* YKK Vislon zipper for easy opening and closing
According to Gore, the company behind Windstopper, "Windstopper fabrics combine total windproofness with maximum breathability. Engineered for a wide range activities and weather conditions, our fabrics are so comfortable and versatile, they often become favourite everyday outdoor garments as well."
I found the Perfetto suitable for temperatures from about 11°C. I expected to get sweaty at about 16°C or so, but the Perfetto Light is breathable enough that it's comfortable enough in warmer conditions too.
I've always found Windstopper fabrics to be very durable. Once the Nano Light Pro panels lose their water-shedding ability you can iron them to renew the performance.
It's a slim, race cut but with enough stretch to accommodate a variety of different builds. It'll fit best if you're slim, but you don't need to be a stickman/woman.
As mentioned, it's a slim cut. I usually take a large, sometimes a medium, and I took a large here.
It's not cheap but it's good value: cheaper than the Gabba (£140) and Endura's FS260-Pro SL Classic (£129.99, inc arm warmers). It's more expensive than Santini's Beta Windstopper Short Sleeve jersey, at £109.99, although Stu was a little critical of the fit, while Jez rated the Stolen Goat Orkaan very highly, at £108.
How easy is the product to care for? How did it respond to being washed?
You just bung it in the washing machine at a low heat along with most of your other cycling stuff and it comes out fine.
The Nano Light fabric becomes gradually less water repellent, but ironing revitalises it. That might sound a bit strange but it does work.
Tell us how the product performed overall when used for its designed purpose
It keeps cold air out effectively and is water repellent too, especially at the front. Plus, it has the added advantage of being highly breathable.

Like the Gabba, this is an exceptional jersey – not surprisingly, because this is essentially the Gabba Lite. You'll use it across a whole range of different temperatures covering a big chunk of the UK calendar, so you're bound to get your money's worth.
