A bit of wind and water are no match for the Castelli Velo Jacket.

The only thing worse than getting caught riding in a cool mist is wearing a rain jacket that seals in body heat and moisture. Even if the rain doesn't wet you, your own sweat will. Castelli's Velo Jacket is a lightweight solution which features breathable fabric and ventilation ports all in a small, portable package. 

The Castelli Velo Jacket was sewn from Forcefield fabric. This extremely lightweight fabric is a 30 gram, ripstop material that is windproof and water-resistant. It's so light, in fact, that you'll barely notice it against your skin. Additionally, it is highly breathable so that when you are working up a sweat you won't get drenched from the inside-out. The Velo jacket features covered ventilation ports on the sleeves and the back to help exhaust heat away from your body. It should be noted that while the Velo jacket is ideal for drizzle or windy conditions, it does not feature fully taped, waterproof seams. If you need a jacket to keep a deluge at bay take a look at the Castelli Pocket Liner Jacket

Cut with a longer back, the Velo jacket helps to keep splash off of your behind. A high mesh collar keeps drizzle from running down your neck, and when the sun comes out, the neck turns into a pocket in which to store the entire jacket. It only takes up half a jersey pocket so it's perfect to carry on those "what if" weather days. Castelli added a reflective logo and back tabs to increase your visibility in low-light conditions.

Castelli's Velo Jacket is available in six sizes from Small to XXX-large and in four colors: White, Orange fluo, Lime, and Black.

Lightweight Protection

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

Castelli is very good at bringing to market cycling items that are very specific to usage. The Velo Jacket, though, is extremely broad in it's real world use. Primarily I have used this as a wind jacket on high mountain descents, to keep off a light drizzle during late spring and summer rides. Also, as an out layer wind barrier over a Gabba jacket during the winter and removing it as temps climbed (or as I climbed). As a stand alone rain jacket, look elsewhere, such as the Riparo Rain Jacket. As others have mentioned, sizing can run small, but I kept true to my Castelli size and bought a medium and it was still a bit blouse-like and flapped in the wind. So as a light insulator on chilly descents or insurance on an iffy cloudy day, the Velo Jacket will be your go to.

great for light rain

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: XL

got this for the days when it has a low chance of showers but always seems to rain in the PNW region. lightweight and gives enough protection from light rain. won't overheat on the semi cool days. got an XL and it fits me about like I want I am ~ 6' and 170lbs. all the castelli stuff seems to run a little small to me. so I always size up with them. good quality for what it is.

its good....

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

I was surprised how transparent it was. I ordered it thinking it was white as pictured, and would have preferred it that way. It is nice and light, cut nicely in the form fitting style, and even though I was unhappy with its semi-transparency I decided to keep it.

Weird fit

  • Familiarity: I've used it several times
  • Fit: True to size

I'm 5'11 and 135, so very rare that something fits me snug. Castelli tends to work in S or M. I hate it when my wind/rain jackets blow around so I went with S.

Standing straight up the jacket fits well, but bending over leaves a few folds of fabric in the front that flat like crazy during high speed descending. It's incredibly annoying and distracting.

The jacket keeps me warm and mostly dry, but the fit needs to be even more tapered in the front (it currently is elongated in the back but appears to be normal length in the front).

really light and packable, runs small

  • Familiarity: I returned this product before using it

too short for me even going up a size

As advertised

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: XL

I got this to fit in my pocket to use as needed for descending in cool weather or for rain. It packs up very small and is easy to fit in a pocket along with some grub or gloves. I haven't yet used it in the rain so I can't speak with experience as to how dry it might keep you, but my sense is that it would work in a light rain but be of little use in a downpour. It does keep the wind out without causing me to overheat. It has nice venting below the arms and down the back. My arms heat up in the jacket when working hard uphill but not too much. I'm very pleased with it so far.

Amazing Velo jacket

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

Recently completed the solvang century, morning was cold and wet. Knowing the temps would soar from the mid 40's to the high 80's, the jacket was perfect, keeping the cold and wet out. I also recently purchased the waterproof version of this jacket for double the cost of this, and must say, this fits 100% better than the same size castelli waterproof light jacket. This runs slightly small, so go up a size. I normally wear a large, so I went xl, and fit snug, but not tight. 2 1/2 hours into the ride, temps soared, misted cleared, too velo jacket off, and easily stuck it in my back pocket for the remainder of the ride. I own many different weight jackets for cycling, and have to say, this is the most functional and user friendly of them all. I'm 5'9, 160lbs

Just a Little of Enough & Packable Too!

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: X-Large

This is the back-up plan when your rolling out on a mid spring or early fall ride in short/er sleeves and think you may need a little more of something in case you linger longer or get a spot of rain before you get finished your ride. Pull this out of your back pocket unfold it and and put it on. Looks great and feels great too. I have two other packable jackets. This one is my new favorite. It's stouter than a similar item from LG and is better made. Bought mine on sale. < $50 is right for this. It has NO pockets save for the one you fold the jacket into for packing. It's a windbreaker folks not for the trail survivalists out there. For me the fit is a winner, I got an XL. (for other brands I wear a Large) It fits over a long sleeve or short sleeve jersey, right.

Where are the pockets?

No pockets.

This is a light, packable windbreaker meant to be worn *over* a jersey or jacket (with rear pockets) for: (a) early starts in cool weather, (b) descending in cool weather and/or (c) as insurance on a day with a sketchy forecast.

Perfect lightweight jacket

  • Fit: Runs small
  • Size Bought: 3XL

This is a great looking, super lightweight jacket that is perfect for chilly starts or days where you're not sure the weather won't go cold or wet after you start. Rolls up to take half the space of a jersey pocket. Seems to vent a bit more than other similar jackets. I'm an XL in Pearl Izumi, but size up 2 times in Castelli to a 3XL as I Have wide shoulders.

great jacket, super packable and portabl

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: XXL

this is a nice jacket to keep in your backpocket or camelback.
its packs very very small into its own pocket. it's super light too.
i have the white, and it's a transparent white.
SIZE UP. they run small. I usually wear XL for american apparel all my castelli is XXL.
the wind protection is excellent and it breathes well, so you dont find yourself sweating in it. just warm.
it does feel like a nylon bag hehe.. but its weight and size makes it a great item to always carry.

Not exactly as in picture

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: Large

I ordered the orange jacket and the interior liner on the jacket I got is red, not black. Same for the zipper. Also, while the picture makes it look like it has a more aero fit, I feel like what I got is less aero than what I was expecting. But at the same time the proportions make my skinny guy gut show less. Just know if you're expecting a more aero fit, it might not be so. Overall I use it with arm and leg warmers on 46F mornings and it's the perfect amount of warmth. Tucks into a little jersey pocket-sized ball, so that's nice too... had it in my jersey pocket when the rain started coming down and it saved me from a wet and cold ride. Super lightweight too. So I like it.

Great Packable Jacket

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: medium

This jacket is super light and is great to just stuff in your bag. The longer hem on the back is nice but the front seems a little too short for my liking. I understand the concept but could've used 1-2 more inches.

Great lightweight windbreaker

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

it's a nice lightweight packable jacket. I use it for morning chilly rides and when it gets warmer I just put in in my back pocket. I bought it for this exact reason and it serves me well. Also it looks great!
As Castelli uses European sizes, I've ordered +1 size and it fits me perfectly.

Just what you need in a light rain

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Small

I just wore this for the first time today. It's ridden in my back pocket on at least half a dozen rides, but this morning it was chilly with warmer temperatures predicted, so I threw it on to start. It is almost completely wind proof, and didn't get sweaty until I really started working. There is some tricky venting in this jacket that lets it breathe a bit without making it too "open" to the elements. Then, with a few miles left in the ride it started to rain lightly and this was just enough to keep from getting too wet. Again, it breathed fairly well in the rain too. For a jacket you can roll up and stuff in your pocket for every ride, this is about perfect. I have the vest too and love that as well. Only complaint, it's a bit baggier than much of my Castelli kit.

I wouldn't say it flaps, but maybe flutters...


    If you are looking for an ultra-lightweight and packable windbreaker, this is a great one.

    The Velo is -much- better than the previous version of this jacket (the Leggero). It is better ventilated (down the sides and the sleeves) and features a much better zipper/guard, better waist band, and other upgrades. This is now a very well done windbreaker with great looks!

    Like all ultra-light, packable, windbreakers this garment is most useful when worn over a jersey or jacket with rear pockets for: (a) descending in cool weather, (b) early starts in cool weather, and/or (c) as insurance on a day with a sketchy forecast.

    I wouldn't generally wear the Velo while riding hard for long periods in cool weather, though less than most, it will still steam up inside (like all windbreakers do).

    Fit: Italian sizing -is- different. With Castelli, size up +1 from your normal street size. Always.

    I'm 5'10" and 185 lbs. The XL fit great here. Enough room to fit over a jersey or jacket, but snug enough not to flap in the wind too badly.

    Portable layer when it gets wet

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    This jacket saved me a few times, when you are out riding and does not know if it really is going to rain. Just fold it and stick on your back pocket and your are done. I have the Yellow Fluo one and it is super light, good quality, super visible in the road.

    I can't see much of a difference between lime and yellow fluo? Is there a real difference in color?

    Also, does this jacket have any pockets?

    I can't answer the color question (I own the black). But there are no pockets here. This is a wind/rain cape designed to wear over your jersey or jacket (which would have rear pockets).

    Good layer for a chilly ride

    • Familiarity: I've put it through the wringer

    I have used this jacket at about 5-15 centigrade degrees, most of the time as a windstopper. I live where it gets cold and warm in a matter of hours (or kms) and often you are caught in rain. It feels more as a windstopper than a rain-proof jacket, but it does repel water nicely. It is very thin, light, and breathes well.
