Castelli Competizione Men’s Bib Tights 269g (L as tested) £130
The Castelli Competizione Men’s Bib Tights are designed for cool to cold conditions, which is a little vague, although I’ve found them extremely temperate with the mercury weaving between 5 and minus 3 or so. Better still, this is all achieved without the bulk traditionally associated with winter tights and the KISS Air Pad employed in other legwear ensures they’ve been comfortable for rides for five hours or so. That said, the lack of a DWR (durable water repelling) coating is a missed opportunity.
Pros: Low bulk, temperate in cool to cold weather, lovely cut and fit, effective pad.
Cons: Lack of DWR coating, bib braces narrower than some.
Specification
Essentially this boils down to a nylon/polyester/elastane mix. Castelli’s Core Due front fabric extends to the knees and employs a tightly knit nylon outer backed with a polyester hollow-core fleece. This tag team is designed to insulate against chill, while trafficking rider generated heat outside. Before we go further, Castelli suggests a riding temperature range between 0 and plus 12 degrees. Seat and back of legs are 3D knit for ease of stretch and ultimately, comfort.

The Bib sections are mesh for a good mix of heat retention and rider generated expulsion; flat elasticated straps are designed for seamless, tactile freedom of movement. They’re a little narrower than some, which hasn’t been a real-world, in the saddle issue but something to consider.
The lower legs are made from the brand’s Thermoflex warm fleece. As we’d hope, flatlock seams run throughout, no discomfort, or indeed branding when it’s time to strip off and hit the tub.

Credit to Castelli, they’re open about the fact Thermoflex is best designed for cool and dry conditions. Raw cut ankle openings manage convenience and comfort. There’s no DWR coating, which is consideration, rather than con and will depend on how persistent and heavy the rainfall is. More about that later. The outer fabric has a satin effect, which for me, strikes the right balance between style and easy cleaning. However, it proved more slippery than their dearer Espresso counterparts.
Pad 3.5/5
This is the Kiss Air 2, which is one down from Castelli’s Progetto X2. It’s also found on the Entrata Thermal Bib Knickers , which I’ve used long term. I’ve had no issues on extended rides-on and indeed, off road, regardless of saddle choice.

However, it is a little thinner and set further back, which is something to consider. The lack of an anti-bacterial is something of a surprise, dare I say culture shock, but there is a wicking skincare top layer, and I can attest to their claims of 5-hour comfort, although not quite the two-year design life before the memory foam loses its prowess. Nonetheless, that in the Entrata is still going strong.
Sizing/Fit 4/5
Castelli’s Sizing chart is, like many others, very accurate. That said, well worth scrutinising carefully beforehand. For example, I’m medium in their Entrata Bib knickers, but large in the Comprtizone and Espresso tights.

Much of this is down to leg length - I’m leggy but short in the torso. That out of the way, Castelli describe the fit as tailored and I also felt this very accurate. We’re talking snug but ultimately flattering and yes, there was enough room around the crotch for those midwinter comfort stops.
Performance 3.5/5
The first half of November was unexpectedly mild-17 and 18 degrees being typical, so too warm for bib tights. Then the mercury slid to subzero, prompting me to switch bikes to spikes and me to bib tights, even after two hours at minus 2, I felt very temperate. Surprising since the Gods were blowing some icy crosswinds at me- conditions where the Espresso showed some limitations. Same story when the mercury climbed to 9 and 10 degrees or so, thanks to the relatively thin, yet sturdy fabric.

The lack of bulk was also very palpable and very conducive of a relatively high 85-90 rpm cadence- allowing for the slippery conditions. Spikes may give the impression of handling “on-rails” but while traction is reassuringly good, going hairball is ill advised. I was surprised by some slight slip with some saddles, not just traditional leather models, either.

We are talking, slip, not surf and given a few miles, minute adjustments became second nature on tarmac and through the trails. Pads and other contact points will always delight some and irk others, but while it lacks the Progetto X2’s outright refinement, the Kiss Air has, er, kept me comfortable, chafe and niff free. Well, I’ve worn ours six straight rides in succession -not practice I’d recommend but by the close of our 5th outing the pad was only starting to emit that “get me to the wash” funk.
Back to movement, the bibs offer excellent defence against icy blasts and though the straps were narrower than I prefer, they’ve displaced the load better than I’d expect and weren’t remotely restrictive when I’ve alternated between hoods and drops.
In these dry contexts, I could cruise along for several hours and remain in the goldilocks zone comfort-wise. When the rains came, I remained generally warm, thanks to the thin pile fleece and wind cheating outer, but navigating waterlogged roads 45 minutes later, my legs were palpably wet. Predictably, this was better with mudguards, but not something café’ owners will thank you for leaving on their seats.
Lighter, though persistent showery rain took a lot longer to have the same effect and given a break in the cloud, that wicking prowess kicked in and at a 90-rpm tempo, I was predominantly dry within 40 minutes- no need for a placing a towel on my office chair, so chances are the café’ would welcome you. I’ve defaulted to Merino blend socks and booties for the most part, but when rains turned monsoon, I also reached for the waterproof socks. While the cuffs are very stretchy, in these contexts, I wore the socks atop, which might sound a faux pas, but kept my calves and feet dry.
While washing a Gore Tex jacket and some other layers, I decided to add a re-proofer, having the hunch it would buy the Competizione some extra time on wet rides. It did fairly convincingly, buying another 30 minutes or so before things became damp, although the fleece retained welcome warmth.

Durability/Care 3.5/5
600 mixed terrain miles later and the Competizione are holding up well- not that I’d expect any issues, but reassuring, given that I’ve been subjecting ours to narrow singletrack and prickly foliage. No bobbling, or similar calling cards. Otherwise, the usual drill pop them in the wash at 30 degrees, with minimal detergent and allow to dry naturally. Given the season and temperatures, this has taken a good 2-3 hours at room temperature - the main garment dries surprisingly quickly but the pad was still a little damp.
Value 3.25/5
In common with the Espresso, there’s nothing earth shattering about the Competizione’s specification. They are, however, well-executed and performance aligns with the marketing. Lusso Perform Winter tights (£125) are made from Polyamide and elastane and also reckoned to enjoy a temperature range between 12 and zero degrees. However, they also boast a DWR layer, which on paper gives them an edge over the Competizione. We’ve not tested them, so cannot comment on their real-world performance. Le Col CC Sport Bib Tight (£175, reduced to £122.50) are said to be “deal for getting in the weekend miles with club mates or commuting through chilly months”.
They also feature a DWR coating and brushed back fabric, although the temperature range is between 5 and 15 degrees, so for cool, rather than cold contexts. The Rivelo ECO Winnats Thermal Bib Tights (£130 now reduced to £65) They’re made from recycled polyamide. Flat locked seams, silicone grippers and mesh bib sections are pretty standard, and zippered cuffs may divide opinion. Endura Men's FS260 Thermo Bib Tights II – Black £125. They feature a long front and ankle zippers, water repelling thermal fabric with DWR coating, gel pad.
Summary
In a nutshell, the Castelli Competizione Men’s Bib Tights do exactly what they say on the tin and to a decent standard. Their effective temperature range and relative lack of bulk may also be a draw for those who find more traditional designs cumbersome. That said, they do face competition from rivals that also boast DWR coatings, and this could sway things, especially in damp climates.
Verdict: 3.5/5 Competent all-rounders for general cool, dry weather riding but lack of DWR coating could be a deal breaker at this price.
