When the asphalt turns soft from a relentless sun, Pearl Izumi's P.R.O. In-R-Cool Shorts' heat-reflective technologies step in to help cool things down. This is partially due to the Coldblack, that is found in Pearl's lightweight and highly-elastic Transfer In-R-Cool fabric, which reduces absorption of sun rays.

This means not only excellent UFP ratings, but improved heat management too. Additionally, these shorts use Pearl Izumi's Transfer Dry fabric, which complements the In-R-Cool with Minerale. This is a porous, highly-absorbent yarn infused with crushed volcanic rock to pull moisture away from the skin, accelerate dry time, and combat odors.

Moving on, the multi-panel design provides an anatomic fit, with structured leg openings that wrap and support your muscles. The inseam measures 9 inches (size Medium) with silicone hems to grip warmers and keep panels securely in place. Finally, no shorts are complete without a quality chamois, which is something Pearl Izumi's well versed in.

On these shorts, the Anatomic P.R.O. Seamless 1:1 insert incorporates variable density padding throughout its three-layer construction. The foam technology means that it's lighter and substantially thinner than previous generations. It maintains a pre-shaped, four-way stretch anatomic shape, and the chamois also incorporates Izumi's Pressure Relief Technology (PRT) and active carbon yarns in order to optimize riding comfort, blood flow, and thermo-regulation.

The Pearl Izumi P.R.O. In-R-Cool Shorts are available in five sizes from Small to XX-Large and in four colors: Black, Black/mykonos blue, Black/true red, and Black/stillwater.

  • Coldblack fabric treatment
  • Silicone grippers
  • Anatomic P.R.O. Seamless 1:1 chamois
  • Moisture wicking In-R-Cool with Minerale fabric

Here's what others have to say...


New style is horrible!

  • Familiarity:I've used it several times
  • Fit:Runs small

I'm not sure when they changed the style but the ones prior to 2015 were great. The padding is thinner and the fit is way tighter. They radically changed them and now they just plain suck! I wore a medium before and now even the large are too small. They are also very slippery when wet and will catch you off-guard when moving around in the saddle. This is the last Pearl Izumi I'll ever buy!


PI shorts at the top

  • Familiarity:I've put it through the wringer

I wear many of the PI products. The quality of the materials is at the top of the spectrum while the prices are usually modest. I normally wear bib shorts, but could not pass up a great sale on the PI Pro shorts. I actually find that after three washings, the chamois is more comfortable. The compression of the pro shorts and bibs is perfect for my body. I stand 5'9" and weigh 144lbs. I buy medium in the PI shorts and bibs. I could go SM but it is way too tight up front, if you catch my drift.


Next Size Up!

  • Familiarity:I've used it several times

I see a lot of bad reviews on the size/fit on these shorts (both in men's and in women's). I usually wear a medium PI Attack or Elite short (183 lb. 5'11"). So I decided to upgrade to the PRO line for once! Way to constricting! I had to return them and get the next size up (large). Now all is happy in nether-land! The only fault is the sizing of these shorts and having to do the return-a-go-go.


A terrible product update

  • Familiarity:I've used it several times

I own a few pairs of last years model here and dreaded to see that they were modified. Sure, you can read the reviews and pretend you don't believe the bad stuff, but believe it here. So I took the plunge and was prepared to be delighted, but was not. I ride 100 - 150 miles a week and am of moderate build and size(5'10", 170#). I bought the "Large" as that is the size I have from last year. The fit in the leg is way too tight up high, so much so that it makes it more difficult to peddle! Even after multiple washes, these bad boys are not loosening up. Way too constraining. I can't believe I'm saying this but I am going to have to find another brand. Farewell Pearl Izumi. You shouldn't have messed up a perfect product.

I am also a long time Pearl loyalist, with similar concerns about the new version of these shorts. I have a 32-33" waist, so I'm right in the range for a Medium, which is what I've had for the last several years. I expect shorts like these to be tight, but these are significantly tighter than previous years' models. They felt quite restrictive after a long, hot ride. Will have to see if they stretch a bit, or try a Large next time.

I feel you "nailed it" in your review Mr. C. I've been a PI customer for a few years but this radical change has me shopping elsewhere.
