How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

Good, but misleading

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

The jacket does have its highs and lows. I want to clear up some misleading details and others misconceptions of what this product is.

First - it is much more red than the picture. I’m talking bright red.

Second - it looks like the logos were kept to a min (as there is only one picture), however, Castelli is slapped along the arm in big letters.

Third - sizing is true! However, it is not to be worn with other layers. This is meant to be worn over your Lycra jersey to stay warm. It is not a daily go to jacket to go to the store in. It is fitted in the arms and waist. Can’t wear layers underneath. That being said, go a size up if you want a daily. Don’t worry, it’s slim enough to be fitted. I got a medium and that sucker is tight but does as it’s meant. I would tell you my dimensions...but I don’t know them. I usually wear a medium and slimmer.

Overall, good jacket just be prepared. Wish it was not misleading in the ONE picture...come on...

Good quality jacket for the value

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

I am 5'7", 145 lbs, ordered SMALL and this jacket fits as expected. Good quality materials and workmanship. Works well on or off the saddle. Highly recommended.

Good cool weather jacket

  • Fit: Runs small
  • Size Bought: XXL

Perfect cool weather jacket. Wish pockets had zipper

Hand pockets are dumb

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

I like the Puro better. It’s pretty much as warm, has regular pockets and a zipper that slides like it’s on butter. This jacket is only slightly better in the rain but has useless hand pockets so I have to wear a jersey underneath and a crappy zipper. Skip

Loved it, but too small

  • Fit: Runs small
  • Size Bought: large

Would have been nice if it fit.

Nice jacket

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

This jacket has an incredible fit. I am 5 feet 11 and half inches and weigh 185 pounds and an XL fits me to a T. Not only is it a nice warm up jacket but it can also be used as another layer on cold days. I just wish I had not waited so long into my 43 cycling career to get it.

Another Excellent Castelli Product

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

I bought this jacket to wear as casual wear because I thought it looked great. It did, in fact, look great when I go it. I took it on a trip with me and was forced to put it into action as a cycling layer when the weather turned colder than planned for. It performed beautifully. So, wear this for riding or to just look good going out. I have a chest measurement of 40 - 41 so I bought the Large because I wanted it to fit close. It fit close just as I wanted. If you are in the 39 - 41 inch range and want it to fit a little looser order an XL.

What is the sizing on this jacket? Is it close fitting like the Gabba or looser?

looser. I could have gone Medium on this but ordered Large where as on the Gabba I have an XL which is an OK size on me (though Large may have worked, but M definitely would have been tight).
