The Q36.5 Gregarius Essential Bib Shorts are superbly comfortable, beautifully made and deliver genuinely premium performance without the premium price tag.

At £140, the Gregarius bibs are actually cheaper than several obvious rivals, yet they still bring Q36.5’s Italian manufacturing, the sophisticated Q LAB Air Chamois and a carefully shaped design geared towards comfort rather than outright compression.

Q36.5 describes them as a high comfort, high mileage option for rides of all lengths and intensities. After using them throughout my summer training and during the Transiberica Transpyrenees, that description feels pretty much spot on.

They became a pair of shorts I instinctively reached for before the longest days in the saddle – largely because the chamois hits an excellent Goldilocks sweet spot between cushioning and bulk. Add impressive build quality, soft straps and excellent warm weather performance, and there is remarkably little to complain about beyond sizing and a fairly limited choice of colours.

Construction and fit

The Gregarius Essential Bib Shorts feel expensive. The presentation is smart without being excessive, and the quality is immediately obvious. The stitching and panel alignment on my test pair were immaculate, with barely a thread out of place.

That fits with Q36.5’s approach to manufacturing. They are made in Italy with the firm saying production takes place within a 350 square kilometre radius of its headquarters in Bolzano. The main fabrics also use entirely recycled yarns, including both polyamide and elastane.

The shaped ‘ergonomic cut’ features relatively few seams and panels and this proved noticeable both on and off the bike. There was no need to shuffle the shorts around when moving between sitting upright, riding on the hoods and getting lower over the front of the bike. They also remained comfortable when walking around during stops, rather than feeling like something that only makes anatomical sense when folded over a bicycle.

Q36.5 has also removed the central seam from the saddle contact area, while the raw cut leg hems avoid conventional silicone grippers. The result is an impressively clean feeling pair of shorts with very little going on internally to cause irritation.

The wide straps are another highlight. They lie flat against the body, spread their load nicely and do not have obvious seams or narrow edges digging into your shoulders. After very long rides, the lack of any noticeable pressure point becomes increasingly valuable.

Around the front, Q36.5 calls its elasticated section the Anti Stress Panel. I would probably call it the belly panel, but perhaps that would not make it past the marketing department.

Either way, it works extremely well. It provides support around the waist without being unnecessarily restrictive – something I was particularly grateful for when pulling the shorts back on after returning from a non cycling summer holiday during which restraint around the buffet had not been a major priority. Q36.5 says the panel is intended to support the pelvic area while adapting to the rider’s shape, and that broadly matches how it feels.

Sizing

Sizing does require some thought. Based purely on my waist measurement, Q36.5’s chart would point me towards a medium, but my large test pair was already quite snug. At 6ft 3in, I would potentially have gone up again to an XL – primarily to gain a little more overall length rather than extra width.

The thighs are not particularly short, but they finished perhaps an inch higher than I would ideally choose. Part of that is admittedly vanity, because most of my other modern bib shorts extend almost to the knee and have therefore established a tan line that I would prefer not to turn into a geological record of the various pairs of shorts I own.

For someone around 6ft or below, I doubt the length will be much of an issue, but taller riders should pay more attention. Q36.5’s sizing chart itself shows quite a spread, depending on whether you prioritise waist, weight or height, so I certainly would not buy purely on waist measurement alone.

Chamois comfort

Ultimately, bib shorts live or die by their chamois, particularly when they are marketed as the perfect high comfort, high mileage option. Thankfully, this is where the Gregarius Essentials really deliver.

The Q LAB Air Chamois uses two layers, which are designed to move independently as the rider changes position. Q36.5 says this construction is intended to maintain protection while reducing friction caused by conventional stitching and overlapping material.

Whatever the theory, the result on the road is excellent. These are among the most comfortable shorts I have used.

Throughout my summer training and during the Transiberica Transpyrenees they became a regular choice for the longest rides. The padding is thick enough to damp out the worst vibration and chatter from poor surfaces, but not so thick that you feel as though you are wearing an adult nappy.

That balance becomes particularly noticeable after several hours. There is plenty of isolation from rough tarmac without losing all connection with the saddle, and I experienced no obvious pressure points or areas where the pad folded or moved underneath me.

The reduced seam count helps here too. There is simply very little inside the shorts demanding your attention, which on a genuinely long ride is exactly what you want.

Warm weather performance

The Gregarius Essential is intended as a three season short, with Q36.5 giving it a ‘body temperature stability guarantee’ above 18°C. Their 188g weight in this large size also puts them firmly towards the lighter end of everyday endurance bibs.

They performed particularly well throughout summer. That included everything from warmer UK training rides to long days in the Pyrenees, where breathability remained very good despite the combination of sustained climbing, heat and some fairly lengthy riding hours.

They also dry impressively quickly. I was caught in summer showers both in the UK and high in the mountains and the shorts never seemed to remain saturated for particularly long once the rain stopped.

The chamois was particularly good in this regard, avoiding that unpleasant soaked sponge sensation that some thicker endurance pads can retain long after the clouds have disappeared.

Styling and practicality

My test shorts came in Black, which is about as safe a cycling wardrobe decision as it is possible to make. They look classy, understated and will work with almost any jersey you choose to combine with them.

If black is not your thing, your only other option is Navy Blue. Both are smart, but a couple more choices would not go amiss, especially given how much more adventurous Q36.5 is with some of its jerseys and jackets.

Reflective detailing is similarly restrained. That keeps the appearance clean, but for bib shorts designed to become an everyday training staple, I would welcome a little more visibility when riding in fading light.

Warranty and crash support

Q36.5 offers more support than the purchase price might suggest. The company covers defects in materials and workmanship for what it calls the practical lifetime of the product, while damage through wear, misuse or neglect may be repaired for what it describes as a nominal charge. It also specifically advertises support in the event of a crash.

It is not as straightforward as brands that promise a fixed crash replacement discount, because the eventual cost depends on Q36.5 assessing the garment and deciding what is practical to repair. Still, having the possibility of getting an expensive bit of cycling clothing repaired rather than immediately throwing it away is welcome.

Value and rivals

Value is arguably one of the Gregarius Essential’s strongest attributes. At £140, calling these inexpensive would be stretching things, but within the increasingly expensive world of premium bib shorts, that price looks remarkably sensible.

Q36.5 manages to combine Italian manufacture, excellent finishing, a sophisticated chamois and genuinely impressive long distance comfort while substantially undercutting several obvious rivals.

The Assos Equipe R Bib Shorts S11 are £165 and remain excellent shorts, with a similarly superb pad and racier fit. The Castelli Espresso 2 costs £185 and also offers excellent long ride comfort.

The Velocio Men’s LUXE Bib Short, meanwhile, are considerably more expensive at £218, as are the Le Col Hors Categorie Bib Shorts, at £260.

That makes the Q36.5 particularly compelling. I would happily put its chamois comfort and overall construction alongside any of those shorts, yet it is cheaper than all of them.

There are less expensive bib shorts available, of course, but among premium options I have tested recently, the Gregarius Essential stands out for the combination of quality, performance and price.

Conclusion

The Q36.5 Gregarius Essential Bib Shorts get most of the important things impressively right. Construction is superb, the straps and minimal seam layout make them exceptionally comfortable, warm weather performance is excellent, and the Anti Stress Panel provides support without trying to punish you for having eaten lunch.

Most importantly, the Q LAB Air Chamois is outstanding. It provides enough cushioning for genuinely huge days without excessive bulk.

Sizing needs some care, particularly for taller riders, and more colour and reflective options would be welcome. At £140, though, those feel like minor complaints. When rivals costing considerably more struggle to offer noticeably greater comfort or construction quality, the Gregarius Essential makes a very persuasive case for itself.

Test Report

What does the manufacturer say about this product?:

Developed to be the perfect high-comfort, high-mileage bib shorts, Q36.5 Gregarius Essential Cycling Bib Shorts are the ideal choice for rides of all lengths and intensities. Their comfort-oriented Democratic Fit with our Super Molded Chamois ensure total in-the-saddle comfort with no pressure points so you can increase your ride time and intensity.

Tell us some more about the technical aspects of this product:

Q36.5’s website says: “The Q36.5 Gregarius Essential Cycling Bib Shorts are the everyday essential bib shorts for rides of all lengths and intensities. They are designed using a minimum of seams and panels to reduce pressure points and the potential for unwanted friction. The result is a 3-season pair of bibs that you can wear for long distance and high intensity training.

“Made using 100% recycled yarns, which not only include recycled polyamide but also recycled elastane, the Gregarius Essential Bib Shorts provide a comfort-oriented fit that supports the muscles without feeling constrictive. The raw cut of the leg hems adds to the level of comfort by keeping the leg cuff in place without resorting to using silicone. The method eliminates hot spots and pressure points on the thigh. The straps have been made light and breathable while still offering exceptional support.

“For the saddle and the chamois interface, we use our proprietary pattern to improve the saddle/chamois intersection which eliminates the central seam which typically causes pressure and discomfort while on the saddle. The pattern replicates the contact surface of the saddle and is made with a molded fabric that adapts naturally to the different typology of saddles. To increase comfort in the pelvic zone, an anti-stress cut allows more freedom of movement and no pressure points.

“The chamois uses a new three-dimensional Super Molded construction that better follows the anatomy of the human body and offers improved comfort during the ride. The foam padding has been calibrated according to the scheme of variable densities and thicknesses in the perineal, ischiatic, genital and gluteal zones resulting in an extremely sophisticated tuning of its overall comfort. The chamois uses a unique molding technique that produces smooth variations in the thickness of the padding, markedly improving the contact with the rider’s skin.

“Designed to be your go-to bib shorts for 3-season training, the Gregarius Essential Cycling Bib Shorts put you in a position to push your limits while remaining extremely comfortable in the saddle.”
