The bibs for pushing it to the limit.

Made to meet Castelli's high standards for comfort and performance in a cycling short, the Men's Unlimited Bib Short meets these expectations all while adding a few extra features that come in handy for riding on any surface. You'll find an exceptional fit as well as the KISS Air2 seat pad, which provides generous anatomically placed padding with an exceptionally soft top layer.

What makes this short special is the extremely durable Unlimited Lycra® fabric. It has higher abrasion resistance and tear resistance while not compromising on the stretch, moisture management or comfort.

Taking the old track rider's trick of wearing two layers of Lycra, these bibs use double-layer side panels to create the fabric-sliding-on-fabric trick, should you fall. This short isn't really meant to be indestructible, but it significantly increases the chances that sliding out on gravel will mean you need to just brush yourself off rather than having to buy a new pair of shorts.

That second layer on the side panel also makes for convenient side pockets, with a flap over the top to prevent the contents from falling out. For added convenience, while riding on and off-road, you have two mesh pockets on the lower back that compress gear next to your body to keep it from bouncing around.

This short adds durability and storage without compromising comfort — for unlimited amounts of fun.


  • Made for fast riding on unlimited terrain
  • 200 g/m2 nylon/Lycra® fabric with best-in-class abrasion and tear resistance
  • 2 mesh rear pockets built into mesh bib straps
  • Double-layer side panels reduce abrasion if you fall, while also creating 2 useful side pockets
  • Raw-cut leg ending with vertical silicone grip strips to hold the leg in place
  • KISS Air2 seat pad for long-distance comfort
  • UNLIMITED Logo on rear of bibs
  • Performance fit: Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you typically wear a Medium, select a Large in Castelli.

    Great endurance bibs - Castelli quality at a great value.

    At the regular price, these are a great value comparable to many quality brand's entry level bibs.

    The double layer of these bib shorts appealed to me. I purchased these immediately after a telephone cable knocked loose from a pole by a truck clothes-lined me and caused a crash. Fortunately, my injuries were minor (a raw scar on the neck and a sore throat, as well as a scratch on my hip) but I did get a hole in the bib shorts - something I'm hoping will not occur with this short. Having the options of pockets are nice as well - great for fuel or phone - although with my history, I would put the phone in a jersey pocket rather than where I tend to land in a crash...

    As for fitment, I am 6'-0", 32" waist, and 180 lbs. My body shape is weird - I have a long torso and used to be 60 lbs heavier, making my rib cage large for my body. I fit a large in this bib short, and would judge them to be just a little smaller than a medium in brands that fit true to size. I do like the extra compression of the slightly tighter fit, the double layer of material will give you a compression feel as well. Compared to the Entrata entry level bib short, I feel that they are built just a little larger. The straps over my longer torso are fitted, but not uncomfortable. That being said, I believe an XL would probably fit as well if wanted a more relaxed fit.

    As for the other features. The chamois is the Kiss Air 2, Castelli's entry level chamois - but is still the nicest one I have in my closet. I have ridden a combination of on and off road rides of ~40 miles with little discomfort. I can only imagine what the nicer chamois' are like... The leg grippers are vertical silicone strips on an un-stitched cuff - incredibly comfortable and grippy. Along with the two side pockets, there are two mesh pockets at the lower back area, allowing you to wear a T-shirt or MTB jersey and still carry your stuff.

    Finally, I like the relatively little branding... especially for a Castelli garment A single logo on you left thigh and the word "Unlimited" stamped above your butt - easily covered by a jersey or shirt.

    2nd Pair of these

    First pair ordered last year have held up incredibly for multiple hour rides. The pockets are bar-none the best, keeping your do-dads close and secure. The graphic on the back is starting to peel but the chamois longevity is all I care about and 10+ hours later it's still plump, not Castelli's best but it's sufficient. This second pair I recently ordered had a label that was caught in the stitching but I cut those out anyway. It also had a slight defect in the right leg where the seam didn't carry all the way down the leg so the panels have a slight split at the opening. Stitching is secure so I don't see it being a problem - just seems quality control is dropping and I may have to find another go-to bib. 6'3" 180lb 33" waist the medium is solid

    The Best Pair of Bibs I've Owned
    by Heath Oates

    I wore to see-through a pair of really popular discount endurance bibs in less than a year of doing long rides. Decided I was going to buy the best value of bibs I could find in the $80-$120 range and see if there was a difference. There was a huge difference. These are now my go-to endurance bibs of choice. They just feel great. They're slightly longer than I normally wear, but they fit tight to my legs. The pockets are really useful if I want to not wear a regular jersay and just wear a t-shirt or a flannel.

    If you are thinking about buying a pair of these and can find them on any kind of discount, I would recommend it!

    5 STAR !!

    If you're a Castelli "fit", these may be for you. These seem to have the thigh Compression similar to Castelli Aero bibs + the Seat Pad Comfort of Castelli Endurance bibs = my new 'Go- To' bibs. Just finished a 100 mi. / low 80�s ride. Thought these maybe be warm with the double layer pockets. Non-issue for me.

    I've had good luck with Castelli's overall quality, fit & finish on any of their bibs, and expect these to be the same. They just seem to last (with proper care of course)

    I look forward to stocking-up on a couple of more pair.

    Purchased for gravel, but perfect for the road, too.

    The KISS Air2 pad is my new favorite, and the biggest reason for my immediate purchase of a second pair. The cargo pockets can easily handle your smart phone or cycling wallet, and there are certain rides when that is a must.

    At 6ft, 200lbs, I bought XXL, and am happy with the fit. For comparison, I wear XL in Le Col, and L in Rapha.

    The logo is more subtle than on my earlier Castelli bibs.

    Go-to Gravel Bibs
    by Anonymous
    1 of 1 customers found this review helpful.

    These are the right length, weight, and fit for a big day in the saddle - I have the olive green bibs and they surprisingly go well with a lot of the kit I already have (or no ones nice enough to tell me the truth). Castelli sizing as usual - I'm 6'5 200 lbs and the XL bibs fit perfectly for me in summer shape.

    Nice bibs. Good leg grippers. Don't provide a ton of compression but are comfy on long rides. The cargo pockets and back pockets near the bib straps are handy when you don't want to wear a pack and/or want a more casual top.

    Great fit and very comfortable for long (3 plus hours rides). The side pockets are very convenient. These provide better and easier access to nutrition particularly when you're hammering those pedals.
