Named after the famed Mortirolo pass, the Castelli Mortirolo Jacket lets you ride comfortably in temperate winter climates. Utilizing some of the technology found on the Espresso Due, this jacket is geared more for riding in moderate temperatures (higher than 46 F) while providing ample wind protection.
The Mortirolo is constructed in two parts. The front utilizes WindStopper X-Fast 2 Fabric, which features four-way stretch, designed to eliminate pulling and bunching while ridingt. Since full windproof coverage isn't needed in moderate temperatures, air-permeable polyester fabric on the back allows body heat to escape while still keeping cool wind off your core.
The Mortirolo is cut in a slim fit to prevent flapping as you ride. The two vertical zippers on the front of the jacket give maximum ventilation when used with the full-length zipper to dump heat while you are climbing. For a light air flow, simply adjust the side vent zippers to where you want them.
The Castelli Mortirolo Jacket is finished off with an elastic gripper along the bottom hem to keep the jacket from riding up. It comes with three rear pockets for your riding essentials and rear reflective tabs and piping on the chest to keep you visible during low-light conditions. It comes in four color combinations- Red/black, Black/white, Anthracite/black, and Camouflage/black and is available in Small through XXX-Large.
This jacket is, in a word, outstanding. As others say about Castelli, make sure to go a size up. I normally wear a large (5-10, 180 lbs, 42 in. chest), but the XL in this jacket is right for me. Still a bit snug, but good. I've worn it now four times in temps ranging from 38 F to 50 F. At the lower end I wore a long sleeve base layer and at the higher end a short sleeve base (Craft in both cases). I was cool but not cold, and the ventilation is great. I especially like the two small front vents. Back pockets are very good. The good form fit prevents the billowing I used to get with my windbreaker. The Windstopper front is effective. All in all, I love it so far.
I finally broke down and bought a good winter cycling jacket and man am I glad I did? This is the single best piece of cycling apparel I own, I love it. Fit is great, I bought an XL and I am 5'10" 175lbs, perfect fit. I only wear a wool long sleeve base layer under it from 0 degs and up. If it gets above 50 deg I only use a thin short sleeved base layer. Its pretty water proof too. The vents work well at the front.
Best of all its a really sharp looking jacket!! I also bought the neoprene Castelli gloves and Sottile jacket and they are the perfect compliment for my winter riding here on the wet West Coast.
I'm 5'11 and 153lbs. I normally wear Castelli medium for all my jerseys and bibs but went a size up on the recommendation of another review. I bought a large and it fits great. Living in California, I do not really use the heavy winter gear. I rode last night with temps of 64 -48 F. The jacket performed great, not too hot and not too cold. Zipped up it keep me warm. Vents on the front are great for letting a bit of air. Zipper is easy to work with a single hand.
Great product and goes with my summer kit colors.
I have two of these jackets and with combinations of different layering I use them down to 25 degrees for 30-40 mile rides. The fit is tight like it should be and the wind protection is great while the back of the jacket breathes. I am 6' and 155 lbs and wear a medium. The only problem with this jacket is the sleeves could be longer so the wrists don't get exposed. I have used these jackets going on three winters now and the quality is fantastic, gotta love Castelli gear.
Wore this on a cold night within the low 40's in SoCal.
Love it. Wasn't sweating profusely, conforms nicely, looks good, dries quickly, very pleased with the product.
The windblocker panels kept me warm even while the winds picked up, making my feet jealous of my torso and arms.
Love this jacket because of the bomber protection in the front and neck.. while the lighter mesh like back keeps you from over heating. Wouldn't recommend for wet weather. Tron camo also gets you some good looks.
Great product - performs as expected - quality, fit, utility. Ideal for spring temps from 45 to 60.
