The ultralight weather-beater.

Ominous clouds on the horizon can be pretty scary when you’re 40 miles out with no shelter in sight. Fortunately, your Castelli Sottile Due jacket can hold off the worst of nature’s onslaught while you pedal for home. Small enough to pack into a jersey pocket, the Sottile Due is made for just such an emergency, and it meets the challenge well.

Castelli made the Sottile Due jacket with a blend of breathable wind-and water-resistant fabrics. Castelli also added mesh panels at the underarms for added breathability and airflow. The body panels are semi-transparent, so you kit and race number stay visible as you ride through the storm. The fit is fairly trim. This keeps the Sottlie Due a packable size and reduces the garbage-bag effect from which many rain jackets suffer.

The Sottile Due was made with a full-length contrasting zipper for additional airflow and easy removal. Rounded elastic banding at the hem and cuffs keep the jacket securely in place. A single-side zipper allows access to jersey pockets, and reflective elements make you more visible in traffic

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: XL
  • Height: 6'2"
  • Weight: 190lbs

Compared with other Castelli garments I own, I was very disappointed with the overall "Quality" of this particular jacket even though the price is low in comparison.

The major issue which caused me to return the jacket unused; it was impossible to fully zip-up the jacket! The zipper's inner backing flap gets pulled into the closing mechanism at about chest high. It took three hands to make it work. I did not want to struggle with this while pedaling on my bike!

My other issue was a small (1") cut across the front of the jacket about waist high probably caused by a box knife. I would have been okay with repairing this myself due to the low price I paid for the jacket, but combined with the zipper issue, I chose to return for refund.

I Like It

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: Large
  • Height: 6'1"
  • Weight: 180lbs

For the price, this is a good piece. It’s very light and does the job of either keeping me warm for early am starts or keeping light rain off me. As others have pointed out, it doesn’t breathe so it’s a sweat monger.

It’s thin and rolls up easily to fit in a jersey pocket. The top of the zipper is funky and need to be hacked to work without trouble.

The L fits me very slim over a tight jersey. It’s plenty long in the body and arms. Good cut for long and lean body type.

Great for the rain, very packable, lightweight and very visible.
The zipper on the back is not a pocket, it just gave access to the maillot's pockets.

Repels showers, maximizes visibility.

Bought it as a gift for a friend who's had major issues with visibility on the road (he was recently hit!). He loves the jacket for its super-bright look and rain-shedding performance.

good but not so breathable

  • Familiarity: I've put it through the wringer

Pro: Very packable. My go to jacket.
Pro: Good water reppellancy
Pro: Warm: use it as shell in winter in cold weather, 30's and 40's. More warm than one might expect, probably because it isn't very breathable.
Con: Not very breathable.

Keeps you warm and repels water

  • Familiarity: I've put it through the wringer

This jacket does what it is intended to do. It repels water and keeps you warm in chilly days. I ride at 5-15 centigrade degrees with a 50% chance of rain most of the time. This jacket keeps me cozy and dry. It is light and folds small. I like the zippers to get access to the back pockets of my jersey. The zipper bites the fabric at the bottom of the neck (slight design problem). I got one in white, and it is totally transparent.

Poor quality control. Seemingly poor RMA

    I ordered the first one and the collar stitching already had come apart before I had received it. The replacetment will not zip all the way up.

    I have spent 45 minutes trying to get crappy internet explorer to print the RMA with out success.

    Also Competitive Cyclist said they would pay for the return but both slips want me to pay $6.99.

    I had bought some other stuff since then, but WOW what a hassle to get the returns taken care of.

    I do like the size large Louis Garneau Corsa 2 bibs so far. Fit and quality for my 6'1" 180 pound frame is good.

    Some of the people will tell you anything to make a sale. I say this because I have been lied to about products I have bought in the past. I was told the pad in the Demarchi bibs was the exact same as the Assos, which was not true. The Pad is very good though.

    I DO NOT RECOMMEND the jacket.

    Great, Sometimes

    • Familiarity: I've used it several times

    I love the idea & packability of this jacket, the actual execution not as much. It's great to stuff in a jersey pocket & barely notice as you're climbing along then throw on over a summit for a long decent. However in changeable conditions or once you start working up a sweat it's a bit like a greenhouse inside. Once the inner fabric gets moisture on it the fabric starts sticking to your skin making removal difficult while riding. The tiny zipper doesn't make things easy either.

    I wanted to love it, but find myself reaching for it only really in good weather with a chilly decent ahead of me.

    Zipper was disappointing

    • Familiarity: I returned this product before using it

    I really wanted a morning ride shell I could shove in my jersey pocket. This jacket has a large flap at the top to ensure a good seal from wind/rain, which is great. BUT, I can't get the dang thing to zip without the big flap getting pulled into the zipper.

    Love the jacket, but zipper isn't working for me.

    I'm opting for a castelli vest and warmers instead.

    first thoughts

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

    great visibility, its more think and see through than i thought it would be, but just as high viz. I got the small even though i wear medium for Castelli jersey and bibs, it was the right call.

    The Bad: no bag! I have a castelli wind vest from lats year and it came with a little pouch you could put it in. that would have been perfect for this, totally needs it.
