Pro Fit Light Rain Jacket

Castelli designed the Pro Fit Light Rain Jacket to be their most aerodynamic rain jacket. Built using high-stretch fabrics with a smooth face, this jacket cuts through wind and rain efficiently while providing a good amount of stretch, ensuring the fabric moves with you for optimal comfort while transitioning in and out of the saddle on tough climbs or sprints. And as the name implies, the jacket is cut for a skin-tight fit on World Tour riders, so keep that in mind when determining your size.

The Pro Fit Light Rain Jacket is made of Castelli's Torrent Stretch fabric with 3-layer construction on the sleeves and 2-layer construction on the main body. Castelli does this to ensure next-to-skin comfort on the sleeves while omitting the inner textile layer on the main body to save weight and keep the piece compact. This ensures the jacket easily packs down into a jersey pocket or saddle bag for those surprise storm cells often encountered during shoulder season riding. The seams are fully sealed, so paired with the polyurethane membrane this jacket is fully waterproof, not just water-resistant. Castelli finishes the jacket with 3 rear storage pockets and a long, Gabba-style tail to protect from road spray—nice features to have on a packable rain jacket.

  • Aerodynamic rain jacket for cycling in inclement weather
  • Aero stretch fit stays comfortable as you cut through wind & rain
  • Main fabric with sealed seams is completely waterproof
  • Jacket packs down tightly for easy storage in a jersey pocket
  • Three rear pockets for stashing food and essentials on the ride
  • Castelli continues to lead the way in race fit cycling gear for variable weather

Good fit, keeps me dry and warm

Got this in red -- matches my bike. So five stars! I'm about 185 lb, 5'11", and ~42" chest, and got an XXL, thinking I was sizing up to fit extra layers underneath. The XXL feels just right -- slim fit in the arms, so no flapping there, but a bit of extra room in the chest if I want to use it over an insulating layer. Been out on two rainy rides, one during cool weather (about 50-55 F), and the jacket kept me dry and warm without trapping a lot of internal moisture. The fabric seems substantial and sturdy, but it still folds up to fit in a jersey pocket OK. I like the rear drape over the butt and the rear pockets. Oh, and I like the red -- practically speaking, it provides good visibility without being fluorescent green! Seems to be worth the price.

I have had this jacket for a few months now and have ridden in it a dozen times in temps ranging from 40 to 60° F, with and without rain. It is perfectly windproof and waterproof. It's downfall is breathability. I've never come back from a ride dry with this jacket on. Never! It's possible I dress too warm - I've never been cold in this jacket (not even soaked with perspiration!), but in spite of unzipping to ventilate, perspiration covers the inside of the jacket and my jersey by ride's end. Love it's appearance. Love it's fit, albeit 'tight' (I'm normally a med. size). The fabric is really different: A soft exterior with a stretchy, white, Goretex-like interior. The 'caution tape' motif on the cuff would seem useful for US riders if it were on the left sleeve. The bottom flap extends far down to divert runoff from soaking your shorts and can be tucked up when not needed. The zipper runs smoothly, all the way up and back down with one hand. The neck is very comfortable. It is VERY visible!!! Final word: there might yet be the perfect rain jacket out there, but I haven't found it. At the sale price ($150) I would consider buying it after reading this review. Maybe I dress too warm!


How would you compare this to the Idro Pro 2 jacket? Other than it's half the price :-). Is the main difference the breathe-ability?

Hey Andrew, The main differences are going to come from the materials used in construction. With the Idro you are getting full Gore Shakedry, this means the Idro will be more waterproof, and breathable. The Pro is still great and will keep you dry in almost any condition, but if you anticipate riding in torrential downpours it might be worth the money for the Idro. Hopefully that helps!

This is a remarkably waterproof piece of clothing. It’s extremely well made. It’s not super-duper breathable, although it’s certainly not terrible. It is pretty windproof. Its focus is on not getting soaked even under intensely wet conditions, and this it does. Use this for when it is full-on raining. This jacket runs terribly small. Castelli garb is always small - that is a given. At 179 cm tall and a slender 64 kg or so, I straddle M and L in bike clothes; M for width and L for length. I ordered the L here, and it almost fits. It’s tight in the underarms and I am not able to layer. The sleeves are nice and long. My wife, who is also slender but with wide shoulders and is 5 feet 7 inches tall, tried it on... fits her great, she’s keeping it. For me, the right size is, strangely enough, XL.

Rode for a couple hours in steady rain with this jacket. It is waterproof, and it breathed well. I was dry after a very wet ride. Love the flourescent green for safety. Crazy drivers here in Ohio.

This jacket seems very nice. It is pretty much as described above (aero), while not being quite as small in fit as some other Castelli jackets (the Cross Warm-up jacket is quite a bit smaller overall and the RoS jersey is a bit more tight around the shoulders and neck). This Pro Fit Light Rain Jacket is made in Romania, and seems to fit like other Castelli items made there: normal to longer in length and slightly tight overall. The upper arms are a bit snug for my liking, but they may stretch out some. The actual shoulder opening does not bind under the arms like many Castelli items that are made in Bosnia which can cause circulation problems, it is just the sleeve tops that are tight for my arms which are slightly large for a 140 pound cyclist. This is more of a comfort-only issue here. I may end up converting it to a vest if they do not stretch out some though. It is much more packable than the thermal Gabba vest, so would fit much easier in a jersey pocket when needed. I haven't yet worn the jacket in rain but do not doubt that it should be sufficient for light to mid rain. I am 5'9", 140lbs. and the medium fits me well (with the slight exception of the upper arms).
