Very good autumn/spring-weight jersey with stretchy windproofing and a fitted cut
Castelli Trasparente Due Wind Jersey
9 10

The Castelli Trasparente Due Wind Jersey is a winner for autumn and spring riding – it has performed superbly over the past few weeks.

The Trasparente is actually one of those tops that splits the difference between a jersey and a jacket. I'll get that in early so you don't write it off as a too expensive jersey. That would be a mistake.

It's made from three different fabrics, the most notable of which is Windstopper X-Lite Plus. This is the same windproof (obviously) and highly water resistant soft shell material that Castelli use for their Gabba Rain Jersey and Aero Rain Lite jersey.

This four-way stretch fabric makes up the whole of the front, the neck, the shoulders and down the top of the arms to the elbows. It also makes an appearance on the central pocket at the back – you know, where you get that line of road spray from your rear wheel if you don't use mudguards. The other two fabrics aren't windproof: one is a roubaix-type material and the other is a little thinner.

What's so good about the Trasparente? For a start, the Windstopper fabric does its job by stopping cold air while also being impressively breathable so you don't get sweaty in there. It's a bit like wearing a jersey with a windproof gilet over the top, but in a single garment. I'd rather the windproofing extended the whole length of the arms rather than stopping at the elbow, but that's a personal preference.

Another thing I really like about the Trasparente is that it's a good, slim cut – and I likes a good, slim cut, me. The stretchy materials mean that it can fit closely without feeling tight, and no cold air comes wafting in as soon as you hit 25mph. The neck is high and close fitting too so you can keep the outside world from getting in there.

The camlock front zip is from YKK and the large puller is easy to grab with gloved hands. Around the back an elastic waist gripper holds the hem in place and you get three pockets, the middle of which will take a waterproof shell easily enough. There's another zipped pocket on the chest that'll hold a mobile phone or a fiver for a mid-ride stop.

Reflective piping on the shoulders and tabs on the back will help you get seen, and the Transparente is available in colours other than black too.

Castelli give the Trasparente a temperature range of 10-18°C. I'm a cold-blooded reptile and even I wouldn't wear it at 18. I'd say 10-16°C, or something like that. That's with just a base layer underneath. You could obviously wear another layer under there and get some more use out of it in lower temperatures.

I have one of these and would happily recommend them to anyone. Fantastic bit of kit.

Dear Castelli, please stop bringing out these wet weather jersey/jacket things. I've got the Gabba short sleeve one and the Aero lite long sleeve one and they work well. I simply can't have any more!

Got the new Gabba convertible long sleeve top the other week and its seeing plenty of use. I have the old Transparente too and it's really good for spring, autumn and most of the summer! My best Castelli tip is to buy from European dealers who don't charge rip-off UK prices and actually stock the full range of sizes and colours.

On advice I purchased an XL and the fit is perfect. I would normally consider myself a large.

Used it with a baselayer on a 65 mile November sportive in the Yorkshire dales. Temperature was circa 5-8 deg deg and road conditions were wet. Several tough climbs and fast descents. If it had been a longer ride I probably would have stashed a gillet as back up.

Its always a balance between being too hot and then too cold. Thats why you need to be prepared to spend the money on good kit. This is good kit!

I have just bought this jacket . I'm a slim build 179cm 70kg 37inch chest and small was just too small . Medium seems about right ( on the bike) . I got it because my endura windchill wore out . Why oh why didn't I get another windchill? The funny thing is, the endura jacket is actually better designed, better built , has a better zip, extra pockets and it actually fits better all round ( I took a small in endura). The worst thing about the castelli is that unlike the endura it doesn't have a 2 inch 'skirt' or Lycra below the bottom of the back pockets. Therefore as soon as you stuff the rear pockets , the elastic strip below the pockets has no contact with your back! It's seems minor but very annoying when you can see endura have designed this feature for just this reason. Ahhhghhhh common castelli get it together please!
