Jerseys over jackets

Like the Kung Fu masters harness the power of two blows into one, Castelli harnessed the power of a jacket into a jersey. The Trasparente Due Wind Long Sleeve Jersey is just as strong as wind jacket, but just as comfortable as your favorite summer-weight jersey. Combining lightweight, patented materials with an anatomic, cycling-specific fit, the Trasparente Due fights the wind and keeps you warm through the shoulder seasons.

Castelli's Trasparente Due Wind jersey is made from both the patented WindStopper X-Lite Plus and Warmer fabrics. As their names suggest, the materials work in concert to insulate and block wind. To shield you from the winter chills where they actually occur, Castelli placed the WindStopper material on the front of the jersey, or as Castelli refers to it, its lightest wind jacket ever. The front is 100% windproof, so you don't have to worry about rogue breezes blowing through the jersey. This, in tandem with the Warmer material on the back, provides a consistent internal temperature. Sure, the jersey is warm, but you don't need to worry about overheating or drowning in your own sweat. Both of the materials are highly breathable and possess excellent moisture transferring properties.

Should you need to dump heat on-the-fly, Castelli included a full-length, camlock zipper on the front of the jersey. And to secure the overall fit of the Trasparente, a multi-panel design has been incorporated with the added assistance of an elastic gripper at waist. Castelli also included three rear pockets and Napoleon zip-pocket to stow your ride essentials, and reflective accents have been placed throughout the jacket for heightened visibility in low-light conditions.

The Castelli Trasparente Due Wind Long Sleeve Jersey is available in six sizes from Small to XXX-Large and in the colors Anthracite/black/yellow fluorescent, Black, Red/black/white, and White/black/cyan.

Great Jersey!

  • Familiarity: I've used it several times

Have had the chance to use this several times in late winter/early spring conditions. I ride near the ocean so while the temps have been 40-45, the cold, damp wind can be a factor. It is really performing well. Fights the wind as promised. Keeps me warm but doesn't bake. Not heavy and the fit is excellent. I'm 6'' 165 lbs and always buy an XL in Castelli. I can put a layer or two underneath and the fit is snug but not binding. Got the blue and it looks great!

nice as a jacket or underlayer

  • Familiarity: I've put it through the wringer

This was a good score. I went with an XL to give room underneath for layering and to make sure the sleeves are long enough for me - 6'1" and 180 lbs with long arms.

This piece is great with just a jersey or base layer in the 45+ degree range. It has worked well with a wool jersey underneath for temps between 35 - 45. And under a thicker jacket for those really cold days.

The only minor gripes are that the pockets sag a bit, so heavy items can feel like they are swaying when you ride aggressively. Also could use a bit more color and reflective on the back to help getting the driver's attention.

Received this in XL all black (nice)...could prob go L but i make sure sleeve length is ample and this certainly is.....nice fit...6'1 170lbs and XL is still body hugging with room for a couple of layers.....50 degrees and up just SS base layer....40-50 add SS jersey....30-40 i am usually in Castelli Mortirolo jacket...this piece needs windstopper on forearm as well because core suffers a bit without it....all in all nice piece for about 40 up to around 65....I guess Poggio is the jacket equivalent to this jersey...i deducted one star because lack of windstopper on forearms

Very Nice Jersey

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

Looks like this may become my go to coupled with a light baselayer for rides from 35degrees and up. very impressed. Initially it looks to light but the wind proofing on the chest is perfect with a baselayer, easy to unzipp and dump a little heat if needed.

Probably my favorite cold weather jersey

  • Familiarity: I've put it through the wringer

This is one of the best jerseys I think I've ever ridden in. Castelli has an impeccable fit that is perfect for me at 5'7", 130lbs (size small). The one gripe I have is that the sleeves aren't windproof, I think it was already mentioned in a previous article, but make sure you have an LS baselayer with warm sleeves on too if it's below the high thirties. I've ridden into the low forties and aside from moderately cold arms, my upper body has remained warm and, more importantly, dry. I've also been caught out in the teens and stuffed some scavenged newspaper in (shout out to my LBS) and been just fine, thanks to the wind blocking properties of the front.

My only worry is the longevity of the zipper, which seems a little frail, but I believe that the pros of this jersey outweigh a small con.

Best piece of cold weather gear ever.

  • Familiarity: I've put it through the wringer

This jersey is a perfect for anywhere from 40 deg to 65 deg. Great slim fit (no flapping in the wind) and keeps you comfortable on chilly days. My go to piece of clothing in for all cold weather rides.

5 5

Just buy it

Part of Castelli's "rosso corsa" top-of-the-line, this is one of the very BEST items that Castelli makes (and that is saying something). Can I give it 6 stars? Also, it looks insanely awesome in all black. Matches perfectly with Castelli's "lightness" full finger gloves in black.

Application: Long-sleeve jersey for riding in coolish weather: 45-65* (depending upon your base layer selection).

PROS: A lot of attention to detail here. The big zipper gripper works well with gloved hands. And the Gore "Windstopper X-Light" fabric works great and doesn't flap in the wind. And yes! -thank you "Lam" below- the front pocket zipper can be used for cooling.

CONS: None. Other than take care with the pocket/chest zipper. It's a little delicate.

FIT: I found that this specific item runs 1/2 size small even for Castelli tops. Anyway, size up one or two sizes -per usual with Castelli- depending upon your BMI. I'm 5'10 185, the XXL fits perfect.

5 5

Buy this!

  • Familiarity: I've put it through the wringer

Absolutely the best piece of cool weather gear you will ever own, if you ride in temperatures from 60 down to 25 degrees. Great high collar, wind-proof body, good zippers and pockets. Just layer as it gets colder, unzip if you get too warm. As with most Castelli buy a size larger. Get 2 for yourself and some for your riding friends. Especially on sale, I love this product.

Mostly Windproof

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

The sleeves are not windproof, so expect cold arms, which make it difficult to keep hands warm. Jersey is typical of Castelli in fit, finish and style. It's a nice piece, it's just not fully windproof in front.

5 5

Good quality and really useful

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

great quality jersey, use it with a base layer and you can ride in many weather conditions.
Size is a little small, I'm 6'1 and 200lb and 41in chest, XL is like a large but is "slim fit", so if you are not a "slim fit guy" ( like me) then you should get one size more. it is short in front but It works for your bike position, I would prefer and XXL but I needed to use it today so I did and I don't regret.

5 5

Typical Castelli quality and sizing

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

I am 6'1/2" and 162 lbs. and find the XL quite comfortable without being overly restrictive, or baggy. However, preference in this respect, depends on whether you lean to "race" or "club" fit.
I did find the discussion about "Hiviz" concerning this product amusing. One person's comment about Hiviz being a "religion" rings true, to some extent. However, after almost turning my car into a cyclist wearing all black, on a black bike, with an asphalt background, I've become more of a true believer!
Agree completely with the use of USB rechargeable lighting, like the Thunderbolt, even in the daytime! You are safer, and cars WILL give you a wider berth. In any case this jersey probably has enough color variation (and white) to be in the "safe" category, by my standards. Don't believe me? Have someone take two articles of clothing about a block away, one white and one black, look away slightly and have them wave each. Now, which is easier to see in your peripheral vision? Bottom line, whatever makes you comfortable out there, do it.

Blocks wind & water resistant

  • Familiarity: I've used it several times

Highly visible colors, and great fit make this full zip jersey a great shoulder pick. Great between 40 and 65 degrees, just alter your base layer accordingly. I purchased a large size . I am 5'7 165 lbs with a 40 inch chest. Front has a wind stopping material, and back a different fabric that breathes well. Get any color while it's on sale. You'll be glad you did.

My favorite winter jersey!

  • Gender: Male
  • Familiarity: I've used it several times

I've using this jersey with a light weight base layer in the 40's degree F and it just feels great and toasty the whole ride. Prior to this, my other jerseys are not warm enough and my jackets are a bit heavier and bulkier than I wanted. This jersey is just perfect for 40-60F range. It's light weight, windproof front and very breathable back as the description. High quality materials, in fact the windproof material is so silky smooth that I feel sliding through the wind with little drag. I don't know if people noticed, but the front pocket is a very neat design because Castelli uses mesh material inside, so I use it as a mini vent when climbing. The combination of colors is great, so no mater which color you choose, you're always visible. I am 5'8" 150lbs and the M fits nicely. The only minor dislike is the big red advertising Castelli waist band in the back.

Great jersey!

  • Familiarity: I've used it several times

Just got this piece at sale price with credit back which turned out to be a great deal. I'm relatively slim at 5'9" 145# 37"chest so there's not alot of choices out there for clothing that isn't loose and flappy in the wind. Because of that, I always look for slim fit/race cut items. When I saw this rossocorsa item on sale it immediately caught my eye and it didn't disappoint. Nice body hugging fit on me. Quality and attention to detail seems good. With a baselayer+midlayer and this jersey, I've been comfortably riding down to a touch below freezing.

Real nice jersey, oozes quality

  • Familiarity: I've used it several times

This is a very nice, high quality jersey. I'm 6'4, 190, 42 chest and the XXL fits very Euro, with enough room to throw a baselayer on underneath. The jersey is a touch short in the front when walking around, which means it's perfect for riding - and as it's cycling gear so I expect to look like a dork when off the bike.

One thing to note is that the Windstopper material stops around the elbows and on cold downhills you WILL feel where it stops.

At the sale price + credits back they had recently it's a no brainer for real Gore Windstopper.

Responded on

Updates after using it a bit. When rides are below 40 you'll definitely want to layer up below and above as this jersey isn't thermal. Also, after using it twice it appears to be made of the type of fabric that will hold scent in - think Capilene, but possibly worse. After the first hour plus ride in it you could smell the jersey holding in stink.

5 5

This is well worth the money!

  • Familiarity: I've used it several times

This jersey works great. It keeps the wind chill off the chest on those cold starts. Warm fleeced material inside keeps you toasty. It fits small like many cycling pieces. I bought a size up. I am 5'10 185 and bought an XL. Snug in the chest but acceptable. Plenty of length in the arms. I really feel this is my best shoulder season piece in my quiver. Great attention to detail. You get what you pay for with this piece. I would recommend it to a friend.

I love the tall collar

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I had problems with jerseys with short collars as wind goes straight to my back when I use the drops which forced me to use a gaiter on hot days. This solved the problem

6ft 155lb Size L fits fine

5 5

Great by itself, and as mid-layer

  • Familiarity: I've put it through the wringer

This jersey is great by itself in the shoulder seasons, and as a mid-layer under a jacket when it's cold. I've comfortably worn it over a Flanders base layer in 50F, and as a mid-layer under a Zoncolan jacket in 30F.

6 ft, 185 lbs, desk jockey physique, XL fits just right.

It would be nice if Castelli had made the back some color more bright than black, for better visibility late in the day spring and fall. How's that for picking nits?

Awesome Jersey

  • Gender: Male
  • Familiarity: I've put it through the wringer

Took the Trasparente on the first ride today. Temp was 43 degrees. I was wearing a short sleeve jersey under this jersey. I was nice and toasty and I could not believe how warm this jersey is. The chest area is completely wind proof but there is a little bit of wind that gets in from the sleeves. I did like this on the uphill parts since it allowed for some cooling.
The jersey appears to be good quality and there are a lot of details worked in. The back is nice and long. Front pocket fits an iPhone.
I am 6 feet tall and 158 lbs and I am wearing a size Large. It is not skin tight but fairly close in some parts. With the other shirt underneath, I like the fit.
UPDATE: I have used this numerous times now and it has become my go-to jersey when it's too cold for a short sleeve jersey. From the 30's all the way to the 50's, this jersey is very comfortable. If it gets too hot, just unzip the front. I have also washed the jersey several times and it is holding up great.

Awesome Jersey

If I'm to compare my jersey and jacket wardrobe to a well-furnished knife block, the Transparente Due falls squarely into the realm of the 8" slicing knife. Every time I break it out, I wish for something a little heavier, a little lighter, a little more windproof, or a little less - which usually makes it perfect for almost everything.

Solidly aimed at the 35-65F temperature range, my joy with the Transparente is derived from being able to hit the top of a climb at full-tilt with it unzipped during a shoulder-season 50 degree day, and a quick zip up the windproof, insulated front makes for a toasty canyon descent so familiar on Utah rides. No fumbling with a wind jacket, no awkward no-handed parachuting down a grade at 35mph. Construction quality is on par with the likes of Giordana, and it's put up with a year of abuse on my end without complaint. The cut is a bit shorter and roomier than many Castelli pieces, I've found, but that makes it ideal for layering. The chest pocket is a convenient vent, and also makes for a nice safe spot to keep ID/phone/keys.

Of course, from time to time, Utah weather lies, and you break out the under 70 degree gear when really you should be wearing something designed for riding in Sub-Saharan Africa.
