Castelli's Mortirolo Jacket is a go-to winter jacket for cyclists of all disciplines, and the Mortirolo Reflex continues the tradition with the addition of reflective paneling for an updated twist on Castelli's classic style.

The big update for this jacket is perforated reflective fabric across the shoulders and lower back to increase visibility in low-light conditions for rainy days and evening rides. The front of the jacket stays the same, being made of Windstopper X-Fast fabric to provide protection against wind and drizzle. This windproof and water repellant fabric combines breathability with internal brushed fleece to keep everything warm and dry on chilly fall and winter rides. The back of the jacket is made of cozy yet breathable Warmer fabric for temperature control, reducing the potential for overheating. It's like having an upgraded version of your favorite fleece blanket along for the ride to fend off the cold and battle the wind.

Castelli also pays attention to the little details. Front zippered chest vents allow for customized ventilation control and a silicone gripper at the waist keeps the jacket in place throughout your ride. The Mortirolo Reflex Jacket's three rear pockets also provide enough space for a spare tube, extra toe warmers, and a few packets of your favorite hot chocolate mix.

Great evening / night visibility

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

Run a bit small and short. The zipper end may poke my neck if zipped up. My other castelli went under the fabric. A better design. It is a keeper since I got a great price. 60% off. Blocks the wind and keep the chill out. Like the pocket vents too

Great winter jacket for mid-Atlantic

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

This jacket plus a long sleeve base layer is comfortable down to freezing for my daily commute of 45 minutes each way. Toward the end of the ride I usually need to unzip a bit. I put another layer over the jacket below freezing and it has worked well.

At night the upper part of the jacket is reflective. I'm short with a big chest "44 and the XXL is the right size for me. It probably wouldn't work for someone really tall.

Good winter jacket

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

I bought this jacket primarily for night riding. Its high visibility panels work exceptionally well and reflect light from a long distance and from multiple angles. The panels are a little inflexible though and top panels especially make it feel a bit bulky. The fit is OK but not great. It’s a little too short in body and sleeves (compared to other Medium Castelli jackets I have). For me it works for between upper 30s (if not too windy) and low 50s. Note that the back of the jacket is not wind/waterproof at all and on a windy day you will definitely feel it. Also any wheelspray will soak it through very fast.

Good winter jacket

Good for 30-45 Degrees F

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

I'm a year-round commuter in Northern California. Most mornings I wear a Castelli long sleeve base layer topped with a Perfetto or Gabba long sleeve jersey. This works most days - wet or dry, morning or evening. When the temperatures drop closer to 30 degrees in the morning, I combine the long sleeve zippered base layer with this Mortirolo jacket. The fleece lining feels great on cold mornings, and the extra thickness of the jacket is just right for colder mornings. As I warm up, I open the chest zipper vents for extra cooling.
This is a great commuter jacket - the extra reflectivity really helps on Winter evenings. Like most reflective coatings, however, they rub off with wear - so it is best not to use this jacket with a backpack. I am just beginning to show wear on the reflective surface after two seasons so it is not fragile, but you will see scuffing with a backpack.
A great jacket at full price. A steal when on sale. This jacket forms the core part of my commuter kit.

Another great Castelli product

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

On their website, Castelli says this jacket is good for cool/cold weather riding down to a range of 43-59°F. I tend to chill easily so I figured I'd try it out in temps a little above that, and to make sure I didn't get cold I wore a long-sleeve wool Castelli base layer. I live in an area with lots of rolling hills and went out for a couple of hours for a moderately hard ride. The temperature when I left the house was 47; when I got back it was 57. As it turned out, I stayed comfortably warm and actually got a little too warm on the hills. I probably could have worn a sleeveless base layer and been just fine.

Anyway ... I think I can validate that the jersey will perform as intended. With a long-sleeve thermal jersey underneath, I can probably get down into the middle to upper 30s!

Slightly Short Sleeve Length

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

Windstopper is great. Warm, fleecy insides are great.
Reflective material is a nice touch (though I am exclusively a day rider).
The sleeves are shorter than their usual jackets and long-sleeve jerseys (I have 2 jackets and 3 l-s jerseys) but not an issue with proper winter gloves (which are usually a bit gauntlet-like).
As for overall fit, according to the chart attached to this jacket's description, it is spot on. I am about a 44" chest and the XXL fits nicely.

run small, not the best quality

  • Familiarity: I returned this product before using it

This time the Castelli winter jacket runs really small and the fit its weird (apart of that you can really notice the difference of their quality from the products manufactured in China Vs. the manufactured in Europe), not the best product and quality

This is a warm jacket.

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

Great for wet, windy and cold rides. I wear a large and it fits tight and very snug. Your upper body will not be cold in this jacket a great buy on sale.

Warm jacket, beware of sizing

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

Purpose: Commuting in Northern Virginia

The good: I haven't put this through a below-freezing ride yet, but even in the mid-30s this jacket is toasty with a thin base layer. The fitted cuffs make it so no wind is going up your sleeve and the vents offer some cooling if things get warmer in the afternoon. The styling is cool and the fit (once you get it right) is pleasant.

The annoying: I don't want to knock a star off due to sizing issues. Believe the reviews - this thing runs small. I thought an XL would cover me as L is my normal sizing, but even that was too small, especially since I planned on wearing base layers as winter progresses. The XXL works, so know thyself before you buy to save yourself from having to send it back.

Once you dial into the Castelli sizing, and assuming it fits your body shape, from then on you are one very happy camper.

Very nice, but sizing caution

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: Large

I have only initial impressions to offer thus far, as I ordered one, tried it on, and am waiting for the next size up to be delivered. The quality and design appear to be excellent, and the reflectivity is pretty amazing. The sizing, however, appears to require sizing up not just the usual 1x I would normally apply to Castelli, but 2x if you hope to put anything under this jacket. I ordered the large, and it was skin tight/extreme race fit with nothing underneath. Since this is for winter riding, I have ordered a XL to see if that works with a light base layer.

Wish I Could Have Kept It

  • Fit: Runs small
  • Size Bought: XXL

Excellent jacket - hands down. Good looking, well tailored, and it fit me well EXCEPT. I have two Castelli LS XXL jerseys and the sleeves are long enough. I thought sleeve length would carry through to their jackets, but if you wear shirts with 37" sleeves, this won't cut the mustard.

great cycling jacket

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

cant say enough good things about this jacket. it is light but warm and has a really good feel on the bike. it does run slightly tight and I am in between a L and XL normally and the XL is snug. great reflector on shoulders for low light conditions. highly recommended

Note on sizing

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

As others have mentioned Castelli runs smalls.
I'm 5'11" and pretty thin--150 lbs -- and a Large fits me perfect. When I say perfect, I mean snug. Race fit.
I nearly ordered a Medium and I'm glad I didn't.

Highly visible at night

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

Was looking for something for the shoulder season where it's still cool and I get caught in or just plan to ride in the dark. The reflective shoulders and waist really light up in the dark and are significantly easier to see than the tiny loops on the back seams of most Castelli jackets.

Cut is average for Castelli. It's cut to be comfortable in the riding position, though it's not as fitted as their Rossa Corsa line. That said, it won't bunch up in the front when in the drops. It has a high standard collar, not the notched drop collar on many of their other jackets, but still does a decent job of keeping the wind out, as do the draft collars in the sleeves. The pockets do a good job of holding everything close without sagging.

Fit and finish is what you would expect from Castelli as is sizing--go up one size if you want room to layer, and even then it will be a close fit.

Temperature wise, I've had this jacket out in the low 50s with a summer base layer underneath. Depending on your tolerance for cold I don't think I'd take it out much warmer than that since it could get too warm. Layered properly, I suspect it could be worn into the low 40s or even upper 30s.

One more "bonus" is that it's a little more discreet (for Castelli, anyway). You'™re not the rolling billboard that you normally are with their kit.

The jacket isn't without its issues. You sacrifice a little breathability anywhere the reflective panels are. This can be mitigated somewhat with the chest vents. Speaking of which, while the main zipper pull is large enough to use with gloves on, the chest vent zippers are small and not as easily adjusted with gloves on. Also, they feel a little delicate so you may want to take it easy if you'™re hard on gear. I would have liked another inch or two in the back, but then I have a long torso and I wear bib knickers/tights which take care of any drafts.

All in all I don't think I would have paid full asking price for this jacket, but at 50% off (at time of review) it'™s a worthy piece of kit to have in your closet.

One more thing: when I took these photos, I didn't turn off the light. It reflects so well the camera metered for the highlights and they're still blown out. It's that bright.
