    Castelli revamped its revolutionary Free Aero Race Shorts for 2015, making them even more breathable, aerodynamic, and supportive than the previous model and introducing a bib-free option for riders who prefer traditional shorts.

    The Free Aeros are made from a blend of fabrics designed for durability and cool breathability, with 30% Lycra for a perfect balance between supportive compression and unrestricted movement. The sides and back also have surface dimpling (kind of like a golf ball) meant to cut through the wind and get you down the road faster. To complete the fit, Castelli's Giro Air leg bands feature a thin, almost mesh-like gripping surface to keep everything in place and eliminate any uncomfortable bunching or pinching — just remember to throw on some sunscreen under the leg bands to avoid getting burnt.

    At the core of these shorts is the Progetto X2 Air Seat Pad, an antimicrobial chamois with seamless construction, four-way stretch, and a perforated foam layer for a soft, ventilated, friction-free ride. The Free Aero Race Shorts also include reflective elements to help keep you visible in low-light conditions for a race-ready short that will get you quickly and comfortably through any summer ride.

    What do you think about this product?

    Have questions about this product?


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

    I have a 42" waist and the 3X is more for someone with a 36" waist. Also, the chamois is for a small crotch and a low mass butt. Other than that, it is made really well and should be super comfortable

    Terrible sales policy

    • Familiarity: I returned this product before using it

    I received these shorts among many other items today from Comp Cyclist. I do most of my shopping online, so I've made it a habit to check the items before opening them.

    Low and behold the package that contained the Aero race shorts, was packaged in differently. The package it was in had clearly been cut open and had a returned item inside. What's more disturbing, is that the item appears to have been used and washed then returned.

    The most discouraging part, is that Comp Cyclist decided to restock and resell this item instead of marking it as defective. What a joke, seriously- take some pride in your work don't do this to people. I'm tempted to return the whole order based on Comp Cylclist's negligence.

    I've attached a photo, so there's no confusion. The package on the left contained a balled up pair of used Aero Race shorts. Thanks, Comp Cyclist!

    Terrible sales policy

    Castillo free aero shorts

    • Fit: Runs small
    • Size Bought: X-large
    • Height: 6'0"
    • Weight: 205lbs

    I bought the recommended and they were to . Small I have wore them about 6 times and they still don,t fit right not worth the money ,don,t buy them you might be mad get them

    Exceeded my expectations

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Medium
    • Height: 5'6"
    • Weight: 138lbs

    I will begin with buying at least 1 size larger than you normally wear. I am 5'6" 138lbs and mediums are tight! After reading reviews I was unsure of spending so much money on a pair of shorts. After my first 35 mile trail ride, I ordered a second pair!!! These shorts are amazingly comfy in all aspects. Love them.

    Great Shorts!

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

    These are, without doubt, the most comfortable shorts I have worn. I will also say they are true to size. I normally wear a large, but was hesitant to order large as I had read so many reviews indicating they run small. When I first took them out of the package, I thought they might, indeed, be too small. But, when I put them on, they stretch nicely and fit perfectly. There is no binding, rubbing or the feeling of restriction. Ventilation is good and they are cool. They seem well made. However, contrary to the picture, showing "Made in Italy" mine were made in El Salvador. However, the workmanship appears good.

    Too small

    • Fit: Runs small
    • Height: 5'6"
    • Weight: 165lbs

    The sizing on Castelli short has gotten much smaller over the past few years. The last pair of bibs I bought needed to be XL's instead of the Med. I usually wear. The last pair of shorts I bought were L, but probably should have been XL's. In the past I have worn mediums. I am 5'6" and 165lbs so for me to need XL's does not seem right. Still love the performance and the Scorpion logo. Castelli needs to check their sizing.

    Castelli home run with the Aero Free!

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Large
    • Height: 5'11"
    • Weight: 175lbs

    If you're like me, you don't like bib shorts, so options are few and far between. I started buying Castelli products about a year ago, beginning with a pair of these Aero Free Race shorts and was immediately sold on them. They are fantastic in every way! Extremely comfortable and feel very light weight, ie "Free". I have two pairs of the race shorts, and one of the endurance. The endurance has the same chamois, but the short material is a bit thicker and doesn't have the same light weight feel, and the gripper material around the leg cuffs feels more rubbery than the Aero Free. Don't let the "Race" name scare you, they're fine for everyday riding. I highly recommend them to anyone!

    bring last year's model back

    • Familiarity: I've used it several times

    i love last year's model so I decided to continue to support Castelli's effort, but wrong decision. maybe they need to leave the perfection untouch. I disliked the wider leg grip and the chamois seems a bit wider. The fit just was not the same as last year's model. I would like buy another one.. until they change it back.

    These run small. look at the size chart.

    • Familiarity: I've put it through the wringer

    I liked my last Castelli shorts so I am back for another. Last time I got 2XL and they fit a little tight. These were 3XL and were as tight or tighter.

    consider size bigger

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

    I normally order and wear large, they fit just perfect.
    But, this one is small, I should have ordered XL.
    I am 6 ft & 170 lb. Everything except size is better than perfect.

    Agreed on the sizing for Castelli. I have purchased their products previously and found that you need to buy one size up from what you would normally select (ie Pearl Izumi, Specialized). I'm also 6'1 and 170. I have the XL jerseys/shorts and they fit well.
