It’s officially summer north of the equator, so it’s that time of year for your warm weather riding wardrobe. The Q36.5 Dolomites Extreme and Gregarius collections offer a wide array of choices to stay cool and look cool.
The pieces in the collections are engineered to excel in the uniquely extreme and volatile conditions found on multi high-pass Dolomite summer riding, where epic climbs in the sun are followed by endless, winding, high speed descents into valleys with an entirely different set of climate conditions.
Gregarius Clima Dolomites Extreme Jersey – $172
Q36.5 sez: With a body mapped cut, the Q36.5 Gregarius Clima Dolomites Extreme Jersey conforms perfectly to the shape of the torso, enhancing the aero benefits. The arms and shoulders are cut to ensure no fabric bunches up behind the neck and no material flaps in the wind. The longer arm length also works to keep an aero edge.
The Dolomites Extreme Jersey is inspired by and dedicated to the extreme Dolomites adventures that are made possible by choosing the right clothing equipment.
PEZ sez: PEZ got the Dolomites Extreme collection’s flagship jersey in the “can’t be missed” tangerine red colorway (it’s also available in black and ice grey). Besides the color, the first thing you notice is the bold graphic on the front. Per Q36.5: the Q36.5 Gregarius Clima Dolomites Extreme Jersey features our new #radarfocus logo first launched with the 2025 Q36.5 Pro Cycling Team kit. The radar is the ultimate symbol of both focus and navigation under difficult conditions, metaphors of the high performance qualities of Q36.5
The graphic is repeated, but smaller, on the back with the full inscription legible: SCIENTIAE OFFICIALIS INVESTIGATOR, which translates as “research scientist.”
The second thing to notice about the Clima Dolomites Extreme Jersey is how light it is. As a jersey designed for riding in the heat of summer and conquering epic climbs, lightness is a key factor.
Q36.5 specs 112 grams for size M
Construction-wise, the Clima Dolomites Extreme Jersey is relatively “conventional”:
- The front is two panels connected by a full-length cam lock zipper
- Two side panels that are a “sheer” material
- A single rear panel with the obligatory three rear pockets that are mesh designed to expand to be able to hold stuff and then reform to lay close against the lower back when empty
- Raw cut raglan sleeves with aero ribbing
- A race no/low collar
1 – front 3D panel, 2- side sheer panel, 3 – rear honeycomb panel, 4 – ribbed sleeves
Instead of silicone gripper, the Clima Dolomites Extreme Jersey relies on an elasticized strip to help keep the jersey in place
What makes the Clima Dolomites Extreme Jersey different from a lot of other jerseys is their proprietary technical materials. The front is a 3-dimensional fabric for wicking and to create a natural air barrier between the skin and the jersey for improved cooling in extreme heat conditions. The back is a honeycomb mesh material designed to move sweat away from the skin to the outer layer where it can evaporate. Again, important for riding in extreme heat conditions.
When I ran my fingers on the inside, I could feel the 3-dimensional aspect of the fabric
Honeycombs for sweat, not honey
What’s also different about the Clima Dolomites Extreme Jersey is how Q36.5 designs the fit: a body mapped cut that conforms perfectly to the shape of the torso, enhancing the aero benefits. The arms and shoulders are cut to ensure no fabric bunches up behind the neck and no material flaps in the wind.
Raw cut sleeve for comfort and ribbed for speed #aero
Per Q36.5’s size guide, I chose XS which fit me (5’8″, 130 pounds, ectomorph) well. Which is to say, a close to the skin race fit but not spray-on uber tight.
Mesh pockets are semi-see through
Gregarius Pro Bib Shorts – $270
Per Q36.5: The Q36.5 Gregarius Pro Bib Shorts have been designed to be super effective as long distance, endurance-oriented bib shorts. They not only have high performance materials with advanced proprietary chamois, but they offer Q36.5 ergogenic Democratic fit to introduce that extra level of freedom of movement, which can become so important in rides that extend beyond 4 or 5 hours.
Made from 100% recycled yarns, the six specialist Italian materials used for the Gregarius Pro Bib Shorts have been strategically placed to offer muscle support where most required, while a minimum of seams are used to ensure total comfort free from friction or pressure points. The feeling of compression is supportive without being restrictive.
PEZ sez:
The Gregarius Pro Bib Shorts are actually one step down from Q36.5’s top-of-the-line Dottorre Pro Bib Shorts, but don’t confuse that with lower quality. Think of them as high end, race quality bibs at a lower price point. If there’s any doubt about that, per Q36.5:
PEZ got a pair of the Gregarius Pro Bib Shorts in goes-with-everything black, but they’re also available in blue that IMHO would pair well with the Gregarius Pro Made in Italy Jersey.
Instead of more commonplace plastic packaging, the Gregarius Pro Bib Shorts come boxed
Construction-wise, the Gregarius Pro Bib Shorts are a lot like most other bib shorts (that’s not a criticism, simply a statement of fact):
- The legs of the shorts section consist of three panels
- The hem of the legs is its own panel (except on the inner section of the leg, which is a leg panel)
- The upper part of the shorts section (that connects to the bib section) has three panels
- All the panels are serge stitched
- The bib section is a Y-back with a mesh back panel and two wide, raw cut straps
Don’t fix what ain’t broken Y-back bib straps
Q36.5 claims 175 grams for size M (mine are XS)
The Gregarius Pro Bib Shorts use four different proprietary materials:
- A more regular stretch/lycra-like material in the main leg panels.
- A ribbed material that feels more like paper to the touch (but isn’t rough against bare skin) in the lumbar support panel at the back. Q36.5 claims that this panel provides additional compression to create a zone of support for the lumbar and gluteal musculature. The improved stability results in increased power output. I have no way to verify or validate this claim, but can say that it’s comfortable enough.
- A different ribbed material for the chamois section
- A material with some grip/friction for the leg hem section.
One of the things I like about the Gregarius Pro Bib Shorts is how they grip at the hem. According to Q35.6: The raw-cut leg hems provide support without squeezing since they don’t employ uncomfortable elastic and silicon strips. They stay in place with no pressure points no matter the intensity of the effort. Rather than using higher compression and/or silicone on the inside at the hem, the leg gripper section/panel uses a material that feels “rough” but comfortable against my bare skin that creates grip. It grips but doesn’t squeeze and feels almost surreal.
Main: The “grippy” material at the leg hem. Inset: “Regular” stretch material that extends down the back of the leg.
Of course, the most important part of any pair of bib shorts is the pad/chamois. The pad in the Gregarius Pro Bib Shorts is different in that it consists of two separate layers: the padding itself and a top layer over the padding that can actually move independently. Q36.5 claims “The top layer and open-air construction reduce friction typically caused by stitching and material overlap” with “superior stability and comfort for the rider.” I’ll just say that the pad is very comfortable in the saddle with the firm compression/cushion I like paired with a race saddle. Of course, everyone’s butt and saddle are different so YMMV.
The yellow you can see through the holes is the actual pad. The grey material is a separate layer over (and not bonded to the pad).
What’s also different is the external material on the underside of the pad/chamois. Instead of stretch lycra like you would find in most shorts, it’s a material that feels almost like paper and is textured with enough “friction” to “lock in” to a comfortable position but not so much that I couldn’t move around on the saddle easily whenever I wanted to change my position.
The lumbar panel (green arrow) and chamois panel (red arrow) may look a lot the same, but they are two different materials
Just like the Gregarius jersey, I chose XS for the Gregarius Pro Bib Shorts, which fit me (5’8″, 130 pounds, ectomorph) the same — a close to the skin race fit but not spray-on uber tight. I know everyone’s tolerances are different, but for me even with firm/very firm compression, the bibs were comfortable.
The Lowcountry isn’t the Dolomites
We’ve had summer-like weather even before summer officially hit here in the Lowcountry. That means 90-something degrees (F) in the middle of the day. But even if temps are “only” in the 80s (F), the feels like temperature is often triple digits. So both hot and humid. I certainly can’t expect air conditioning, but the Clima Dolomites Extreme Jersey (with a baselayer) has done well keeping me as “cool,” i.e., not overheated, as can be expected under those conditions.
So (at least for me) the kit passes test for the hot weather riding it’s intended for (but I know that everyone’s heat tolerances are different so YMMV).
My longest riding these days is a very occasional 50 miles or so and the Gregarius Pro Bib Shorts have been up to the task (again, in the heat and humidity). Definitely very comfortable in the saddle. And there’s a somewhat sublime aspect to it with the top layer that’s separate from the pad. My butt-o-meter tells me they’d be good for much longer rides (remember, these are bib shorts that Q36.5 Team riders can choose to wear so they have to be up to snuff for long stages in Grand Tours and epic one-day races like the Monuments).
What I can’t attest to is whether the Q36.5 kit lives up to the Dolomites witgh epic climbs/winding descents part attributed to it. It’s flat, flat, flat here in the Lowcountry. The only “climb” (and corresponding descent) I’m doing these days is going up and over (twice … once in each direction) the Cross Island Bridge on the Sunday group ride I do on Hilton Head Island (basically a quarter-mile at 4% average gradient and a whopping 52 feet of elevation gain!)
The Cross Island Bridge at sunset … pretty, but definitely not the Dolomites
