    Shorts for training, racing, and everything in between.

    Castelli’s Evoluzione Bib Shorts challenged our notions of what a sub-$100 pair of bibs could be. By including its famed KISS3 chamois, and the ultra-wicking ProDry2Strati fabric, Castelli pretty much had this one won before anyone else had their lead-outs sorted.

    Not content to stop at fabrics and chamois, though, the Evoluzione is also cut from 8 different panels of fabric to ensure a precise fit. These panels are then sewn together with a dual-needle stitch for durability. Castelli finishes off the job with molded-in silicone leg grippers to keep the shorts in place and comfortable.

    Looks great, not the best quality.

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Large

    Love the look and feel of these bibs, but after a couple of washes the Castelli sticker on the butt started to peel off, and the netting on the bibs showed a small tear. But for the price and comfort I would check em out. Not my favorite pair of bibs but love Castelli so don't stray away from them:) Also go one size up, runs small.

    Poor Quality

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Medium

    These shorts are poor quality. The first pair I bought had a ripped seam out of the box. I sent them back for an exchange. The second pair I have worn twice and a seam has blown out on them. Fabric and features are great but the quality is awful!

    Not My Favorite

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: large

    These are great bibs for the price... With that being said, they're not all that great. The stitching on the straps seem to be of very poor quality, and I feel like I'm going to pull the straps apart trying to pull them on. If I want a tight "race fit," I go with a medium in Castelli. I wanted an everyday, comfortable bib this time, so I went with a Large. In somewhat true Castelli fashion, the straps still feel like they're pulling on my shoulders. This isn't a major issue since Castelli is known to fit small, but I figured they'd be a bit more comfortable by sizing up. I don't have anything poor to say about the chamois, and the legs feel fine. I'd say they're good for the money... but they're not great.

    As other have said, poor stitching, fit and a thin chamois. Not very comfortable and certainly wouldn't wear for a ride more than 2 hours... Generally only wear for indoor training sessions. Would also says the straps don't hold their shape very well so they tend to roll up vs lay flat. Would not recommend.

    You get what you pay for.

    These are decent bibs for sub $100 but you should know up front that they will not wow you. The fit is not as forgiving or flattering as with more expensive bibs from Castelli, even though the chamois is still very good. It felt a little small compared to the other castelli bibs in my closet. As one guy mentioned, you are prone to the mamal--or moose knuckle--when you wear these bibs, as well as a tendency for it to ride up in the rear. They also do not breathe as well as a more expensive and better designed bib such as a velocissimo level piece of kit. That being said, on the bike they are comfortable--if still a little rough--and have proven more durable for me than for some of the other reviewers. washing on cold/gentle and air drying has gone a long way to preserving them. And for the price, I can have a couple in my riding rotation and save my good chamois for the long days. I tend to use this bib for commuting and sub 3 hour rides. With a quality chamois, the only thing limiting these bibs is the less breathable and less comfortable fabric of the shorts.

    Poor bib strap stitching

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

    I have 2 pairs of these. On both pair, the stiching on the mesh bib straps is coming out after a month of use. I wash them on delicate and hang dry them. Very dissappointing.

    Nice bibs for the price

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large

    I ordered the large in the black/yellow fluo colorway, and really like the bibs so far.

    I'm 5'7", 175lb with a 33-inch waist and am "all about that bass," and the L gives me a supportive, compression fit without feeling uncomfortably tight.

    I really like the chamois. It's the most comfortable I've used, although my main point of comparison is entry-level Pearl Izumi.

    I haven't had it long enough to speak to the durability, but I don't see any obvious flaws in construction. Assuming it holds up okay, I will likely buy another pair or two.

    Worst quality Castelli I have bought.

    • Familiarity: I've used it several times

    I needed a new pair of bib shorts and have used Castelli (the more expensive ones) in the past but these are pretty low quality and I wont buy them again.

    The leg gripper stitching has come undone after only 5 rides, around 300 miles, the over the shoulder straps on the one side have started coming undone as well.

    Very poor quality for the price, not recommended.

    Major Mammal Toe!!!

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: XL & XXL

    Runs way small. Tried the XL first, wasn't comfortable, and had major mammal toe (male camel toe). Exchanged for XXL, and the mammal toe was still pronounced. Tried on my Capo bib shorts, size XL, and no mammal toe. Not sure if it's a Castelli thing... but I won't be buying bibs online without trying on first in the future... OR maybe it's just a sign not to buy the cheapest item you can find...

    Sergio, you've never been a high level athlete for sure. They just absolutely DONT care about it. If you have to ride 200km you simply cannot have anything loose and I would even say ( I'm a woman and have been in cycling almost all my life) if a guy has nothing bulging than it would be a little humiliating, high level cyclists even proud of showing their size. And if they have to be pictured the coach would remind them to put their members neatly.

    Slim fit -- good with a cutout saddle

    • Fit: Runs small
    • Size Bought: XL

    The first impression was...THESE THINGS ARE TIGHT!

    That was in the first week of January coming off of six weeks of rich food and zero regard for nutrition and training.

    I have worn them with two different saddles and I will say the saddle with the cutout/valley section works much better with the Kiss3 pad system.

    i wash all of my cycling clothes on the delicate cycle and never put them in the dryer. I see no issues with durability/construction quality.

    Definitely worth a look at this price!

    "They're Awesome"

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: Runs small

    Purchased these as a gift, his first pair of bibs and he digs them. Make sure you measure out the torso length, you may be need size up, Castelli usually runs a bit small. Purchased a Medium and returned for a Large, he's 6' 160 and short in the torso.

    Not comfortable and easily ripped

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

    I'm 5'11" and 170lbs. I usually wear L for Castelli product. Ordered this one size L, so far so good. First ride, the seam on the strap ripped. First ride! Subsequent wears caused uncomfortable numbness in the groin area during long rides. Definitely not recommended. I can only use this bib short now for short training ride.

    Good for the price.

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

    Very good for the price, I'm well satisfied with this product. I use it for long runs and is well comfortable.

    High hopes

    • Familiarity: I've used it several times

    Like several others have mentioned, these run a bit small/tight but I came to appreciate that about them and these quickly became my go-o bib. That is, until the gripper elastic around one of the legs became "unglued" (it doesn't appear to be sewn) from the cuff material. This was only after two months of use. I realize these aren't top shelf bibs but I followed the care instructions and didn't otherwise abuse them so I would expect more than 2 months of use out of them.

    What size I am

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

    I bought these in size medium as a crap shoot. I'm one of those people that typically wear a size in the middle of a medium and large. 5'11" and 160lbs. When I pulled them out of the package, I was thinking "oh crud, I should've got the large", but when I tried them on on, I was very happy with the fit. They fit. FWIW: I like my cycling kits to be race tight.

    Excellent 1st bib.

    • Familiarity: I've put it through the wringer

    These bib shorts were the beginning of me allowing myself to invest in a hobby, and I really appreciate them for that. For the money I spent on them, they helped me so much in my progression as a cyclist. I only wish I'd not been hospitalized from being hit by a car while wearing them, and getting them subsequently destroyed, otherwise I'd still be wearing them!

    If you're looking for a great quality bib that has a simple aesthetic at an easily-digested price, then I highly recommend these.

    Horrible Bibs

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

    Sizing is very small. I fit right in the middle if their large category on the chart, ordered a large, and have to fight to get them on. Very uncomfortable once they're on also. Cheap material. I'm going back to Pearl Izumis. These suck!
