Unlimited Bib Short

Ride often enough and we all come up with a very particular list of what would make a pair of bibs or kit better than its current state. We find ourselves daydreaming about the what-ifs of kit design and construction to come up with that perfect solution to the all-road rides we find ourselves taking these days. Castelli’s designers were on the same wavelength, as the Unlimited Bib Short has all the features we’ve been thinking of to make them perfect for all-day all-terrain rides, with integrated pockets and strategic double-layered fabric.

The Unlimited Bib upper hosts two integrated mesh pockets, which not only help to store extra fuel and essentials for long rides but also make it easy to pair the bibs with just a t-shirt for a more casual, single-track focused outing. With our rides challenging our notion of what is acceptable to cover on narrow tires, the Unlimited Bibs double-layer construction helps ensure we arrive back at home in one piece. Along the thigh and hip, there are two layers of Castelli’s Unlimited Lycra, which is more tear and abrasion-resistant, without feeling constrictive or heavy. This double layer acts as a slip-plane in event of a fall, while also providing sneaky pockets for those extra groceries.

The Unlimited Bibs share many of the same features as our other favorite shorts from Castelli. A KISS Air2 insert has a micro-perforated padding to ventilate as well as it cushions against mixed terrain. The mesh bib upper breathes well and lays flat beneath either jersey or t-shirt.

Winner for Me

Size Bought:
5' 11"

XL sizing was spot on for me at 5'11 and 175 lbs. While I appreciate the look and fabric feel of Assos bibs, Castelli chamois just work better for me and the cheaper price is a nice bonus. I bought the Forest Gray color as it was the only in-stock option, and now I really like the look. Most importantly, my first ride in these was a 103 mile fondo and they were so comfortable. I will say it was not a hot day so I cannot speak to the breathability of the bibs. But they are an absolute winner for me so far. Of course, the additional storage is really handy for long rides.

Great Bibs...

I've put it through the wringer

Great fitting bibs. Are true to size and very good quality material. Enjoy the fact that they have no elastic band at bottom that could eventual stretch out. The padding is just right for a longer ride of several hours and the pockets are extremely useful as I often wear zipper less jerseys with no pockets. This is my second pair. Not that I wore out the first pair. I liked the first so much I got this second pair in a different color.
