‘All bib shorts are created equal, but some are more equal than others’, to misquote George Orwell, and with their Premio Evo Bibshort Castelli aims to make the inequality greater than ever. Unashamedly premium, the shorts are Castelli’s most expensive and claim to offer the ultimate in ‘long-distance comfort, support, speed and durability’.
The Premio Evo range is concise to say the least, and consists of jersey, shorts, mitts, cap and socks, so no warm, windproof or waterproof garments. The shorts and jersey are, however, available in a women’s version.

Castelli’s aim with this range isn’t, apparently, to make the fastest, lightest or most aerodynamic clothing – they have other products which cover these requirements, but instead to make the ‘best’ cycling clothing. This is an interesting take on things when so many products are pushed for their performance benefits, and clearly much more subjective.
Construction
First things first – the pad. I was a little disappointed to see that this headlining bib short uses Castelli’s Progetto X2 Air Seamless pad.
Don’t get me wrong, it’s a perfectly good pad, but it is available in shorts that cost less than half of the price of the Premio Evo, which puts an awful lot of the heavy lifting, price-wise at least, on the rest of the shorts.

The Progetto X2 Air is used in all of Castelli’s premium shorts and tights. It is composed of a seamless, bacteriostatic skin care layer with good airflow, and a multi-density, variable-thickness foam layer featuring perforated gel inserts. The outer edges of the pad are much thinner than the middle sections, with three labelled areas under the sit bones and perineum using even firmer cushioning.
So, if the cash hasn’t been spent on the pad, what is so special about the material and design of the shorts? ‘Gradient stretch woven fabric’ is the quick answer.
This means that within a single panel of fabric, the density and construction can vary without requiring a different piece of material. So, just three panels are used for the entire pair of shorts, ie. the leg panel is raw cut with rubberised yarns for grip, the thigh area has a lighter, stretchier construction to allow the muscles to move without restriction and the fabric around the pelvis has more integrity to provide compression and support for for the seat pad. The lower thigh also features light ribbing, although it isn’t clear whether that is supposed to be for aero gains or just visual interest.

The rear section is double thickness to avoid anyone’s blushes as the fabric is stretched thin over the backside. Strangely, this area has a subtle Rosso Corsa logo even though the Premio Evo doesn’t appear in the Rosso Corsa collection. Indeed, unlike the Premio Evo Jersey, the words ‘Premio Evo’ don’t appear on the shorts at all.
The feel of the fabric is best described as being like a very, very lightweight softshell, complete with slight rustle, just like the Premio Evo Jersey.
Fairly substantial bib straps are connected to a very light back piece that has perforations for breathability. The straps are 50mm wide over the shoulder, although they do narrow slightly where they join the shorts. The upper half of these bibs feels a bit anachronistic when compared to the lower half; a more modern, fully laser-cut construction, such as that found on the Santini Unico Edge Bib Shorts, would have felt more in keeping.
Branding is minimal in the extreme, with a small, tonal ‘Castelli’ on the left thigh, a tiny scorpion that will be covered by a jersey and ‘Castelli’ on the straps, which will also be under a jersey.

Black, Smoky Gray and Belgian Blue are the colour options for men, in XS to 3XL. Ladies have the same colour choices in XS to XL, although there is also a bibless version for women, too, but only in black.
The Ride
Pulling the Premio Evo Bibshort on, they felt great – the textured, rubberised hems didn’t catch or snag but felt very secure once in place, and the leg length was similar to my other favoured shorts, so no tan line mismatch issues! The stretch woven fabric felt tough, supportive and light at the same time, with a well-judged amount of give and compression.
The broad shoulder straps were comfy enough, but perhaps a touch too short on me compared to Castelli’s Espresso Bibshort, or at least, the elastic was a bit stronger (size large shorts, 186cm tall). However, the load was certainly spread across a nice, wide area. On the subject of sizing, the size Large shorts fitted exactly as I’d expected, so sizing is consistent with other Castelli shorts, as well as shorts from Santini, Sportful, Assos, and UC, among others.

100km plus rides in the recent heatwave didn’t faze the shorts, and neither did long, hilly rides in the Julian Alps and Dolomites. Indeed, no matter the temperature or exertion levels (Zoncolan anyone…?), the shorts remained the least of my worries. There was little in the way of unsightly sweat patches, and the grippers didn’t cause any irritation to my legs in the way that some silicone hems can under extreme conditions.
I have lots of experience with the Progetto X2 Air Seamless pad in everything from winter bibs to summer shorts, and although it is perhaps not my absolute favourite pad, it is reliably comfortable and worry-free. After well in excess of 10,000km wearing products that feature the Progetto X2 Air, I’d have no qualms heading straight out on a long, hard ride wearing new shorts with it in. Indeed, that is exactly what I did with the Premio Evo Bibshort, their first outing was 5 hours in the Peak District.

After quite a few wear/wash cycles, there doesn’t appear to be any wear or colour fading on the shorts, and I suspect that the stretch woven material will prove to be very tough and durable. In fact, were it not for the price, I think that these would probably make excellent gravel shorts as the fabric looks to be ideal for the rough and potential tumble of off-road riding.
Value and conclusion
If my words above seem slightly lukewarm, it’s because my every thought and consideration regarding the shorts was always tempered with the knowledge that they cost £300 / $350. That is roughly twice as much as the amount that I would consider high-end. Castelli’s own Espresso Bibshort is £175 / $200, with the same pad. So, no matter how nice the Premio Evo Bibshort is, it is a little hard to get super enthusiastic about it when the price is so high.
My conclusion, just as it was with the Premio Evo Jersey is, yes, the shorts are comfortable, interesting and innovative, but I would much rather have two pairs of £150 shorts than one £300 pair. If Castelli had used a different pad to differentiate the Premio Evos from their other shorts (and if that pad proved itself to be superb), then my answer might be different, but they didn’t.
We all want to be as comfortable as possible on the bike, but rarely, if ever, have I thought that it was the fabric of the shorts causing my discomfort. Thus, whilst the stretch woven material is unique and does work well, any slight improvement it offers over normal material is fairly minimal and doesn’t justify the triple figure jump in price, in my opinion.

However, I love that brands like Castelli make premium halo products like this that use different fabrics, technologies and construction methods. They create talking points and might end up with some of the tech trickling down to more affordable products. Furthermore, other brands such as Assos, Pas Normal Studios and SYN all have products around this price point, so clearly there is a worthwhile market for them.
I am going to give the shorts the same 4 star rating that I gave the jersey, for the same reasons; performance is great, but they don’t offer enough of a performance or comfort advantage over less expensive shorts for most of us to be able to justify the cost.
