Castelli Mortirolo Reflex Jacket

Get noticed.

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.

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.

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

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.

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.
