Reveal your In-R-Cool.

The folks at Pearl Izumi are known for packing at on of value into everything they make. The P.R.O. In-R-Cool short isn’t just an example of this, it’s the poster child. The P.R.O. combines high-tech materials with non-nonsense anatomic design for a cool, comfortable, warm-weather bib short that won’t break the bank.

The P.R.O.’s main body fabric is lightweight, stretchy, Transfer In-R-Cool. It’s been treated with ColdBlack, which reduces the surface of the fabric. The short also made with Minerale, a yarn that’s infused with crushed volcanic rock that actively pulls moisture away from the skin and accelerates dry time to keep you dry and odor-free. The bib straps are made with Direct-Vent mesh to promote cooling airflow.

For the insert, Pearl izumi chose its Anatomic P.R.O. chamois. The insert’s 3-layer construction incorporates variable density padding and a four-way stretch anatomic shape. This shape uses Pearl Izumi’s Pressure Relief Channel to eliminate numbness and promote comfort during long rides.

  • ColdBlack treatment
  • Minerale yarn
  • 9-inch inseam
  • Direct-Vent mesh bib straps
  • Anatomic P.R.O. seamless insert

Fit well, comfortable chamois

  • Familiarity:I've put it through the wringer
  • Fit:True to size
  • Height: 5'10"
    Weight: 143 lbs
    Size Purchased: Medium

Tried several other brands but find the PI bib's fit me the best. Use them in summer when temperatures run 85-100 degrees F. Generally ride with them about 10,000 miles/year. Unlike other reviewers, I actually like the slightly shorter leg length. I use insulated PI bibs for cooler weather. They have a longer leg length.


Solid, Minor Issue

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'10"
    Weight: 175 lbs
    Size Purchased: Medium

I've worn these 5 times for distances between 25 and 85 miles, with good results. The torso and shoulder straps are just right for me with a 33" waist. The mesh is nice and keeps me from overheating as long as I zip down the jersey a bit. The legs are a bit tighter than I would have originally liked, but I've gotten used to it and actually prefer it as it helps support the quads on longer rides. The chamois is thin, but comfortable and hasn't been as issue. I have a Fizik Arione CX saddle for reference. The one reason this doesn't get 5 stars is that the legs are a little shorter than I'd like. If PI added another inch or so to the legs I'd be happy.


Great compression for extended efforts

  • Familiarity:I've used it once or twice and have initial impressions

I've owned a number of Pearl Izumi bibs and shorts. The mediums have always fit me true to size, and I've always thought well of the inserts on the upper level products (had issues with the Attack inserts way back when). I recently bought a pair of the Elite knickers for a cool-evening, return-commute bottom along with a pair of these PRO In-R-Cool bib shorts. The insert is really nice, an improvement over those stitched into an earlier iteration of this bib I own (3 or 4 years old?). The other I like is the Castelli progetto. But this Pearl Izumi insert is possibly nicer. It's certainly newer. So we'll see how time wears on it. But it works effectively two rides into the life of the garment - some longer rides with substantial climbing. The fit is also very good. But I understand what some of the other reviewers mean about it feeling tight. It simply incorporates some compression into the fit and design. But once you're out there doing what you do on a bike, that sensation - if initially unsettling - falls by the wayside. Compared to the Elite knickers I just got, the PROs do feel a little tighter. ( I also like the knickers, by the way.) But it's just the compression feature doing its thing. They feel great, and I experienced no binding or numbness anywhere from them, whether I was in the saddle climbing or in the drops descending. I have Castelli's, Pearl Izumi, Capo (if you're into horse saddle sized inserts - rain rides!) and Gore bibs. These are now my favorites. There are my two cents.


Nice bibs but smaller leg size

  • Familiarity:I've used it several times

Pretty nice bibs, comfortable and the legs have a nice compression feel. I will say that these run small compared to other bibs. I wear an small in Assos, Capo, and Castelli but had to get a medium in these because my legs will not fit through the smalls. That tends to be a trend with PI, they all have small legs.


Best $63.00 Bibs

  • Gender:Male
  • Familiarity:I've put it through the wringer

These are excellent bibs, good compression and the chamois is comfortable for longer rides. Only complaint is I wish the legs were a bit longer and I wish I could have gotten all black at the sale price. Otherwise they are one of my go to bibs.

Do these bibs run small compared to the...

Do these bibs run small compared to the 2013 and 2012 versions?

I have noticed comments on other sites that this years 2014 Pro In R Cool bibs run small and if I used a medium previously I need a large now.

Please assist.

These bibs run true to the sizes shown on the fit chart. They are a compression fit and the correct sizing will yield a tight short. Over previous years the only changes are a slightly lower front that will make it easier on you when nature calls and a thin panel in the back that will improve ventilation properties.

I am 5'8" and 160lbs and tried both the medium and large 2014 bibs. The mediums fit too tight around my upper thighs and the large was too loose around my waist and clearly made for a taller and wider individual. I think these bibs are true to size as indicated in the charts, but I think you need regular to narrow thighs to comfortably fit into the product. I also tried on the P.R.O. Leader Bibs in medium and large, which have a slightly different stitching pattern, and the mediums fit well.

On a separate note, the material and stitching quality were excellent and the chamois is superb.


Excellent Bib for the Money!

  • Familiarity:I gave it as a gift but have feedback to share

These are a top notch bib for their price. The materials are very comfortable, size is very true to chart and larger than typical Euro fittings. The chamois is comfortable for longer rides and the leg hems simply disappear while riding. There are lighter weight bibs, but I think that the PI Pro In-R-Cool has hit the mark for excellent fit, great material quality, very good chamois, very good looks all at a perfect price point, not to mention typical Pearl Izumi quality for durability.


Solid bib but on the short side

  • Gender:Male
  • Familiarity:I've used it several times

Solid bib in my opinion. No doubt that the chamois is placed slightly further forward than most but overall did not bother me. The chamois is very comfortable, especially on the long rides. The chamois pad is also smooth, no "anatomical" bumps, raised pads, etc which I really liked. The only complaint is that the inseam is on the short side. I'm 6' 2'', with a 32 waist, and a close to 36" inseam, and the Medium shorts tend to ride up a bit, almost to mid-thigh despite the shorts having some great leg grippers.


Not great

  • Familiarity:I've used it several times

I tried a pair of these but they didn't work because the pad was sewn to far forward. This resulted in my sit bones sitting on the chamois stitching, which resulted in chaffing and an padded (uncomfortable feel). I wish manufactures would use a bigger pad in the bigger size shorts. I used a size XL. The rest of the shorts felt good though, although they are little too long for my liking. I prefer my short to not touch my knee caps.
