Cool running.

Stay cool during summer events with Pearl Izumi's Elite In-R-Cool Tri Shorts. Constructed from Izumi's Coldblack-treated Elite Transfer fabric, you'll experience temperature-regulating technologies that both reflect heat and block ultraviolet light.

Unlike common dark textiles, which absorb heat, Coldblack treated fabrics have a UPF 50+ rating and actually reflect the sun's radiant energy. In fact, the makers of Coldblack claim that fabric surface temperatures are reduced by to 35 degrees Fahrenheit. So, this alone will aid in the avoidance of overheating during the ride and run stages of your race. However, Izumi's Transfer fabric, with In-R-Cool technology, also performs much of the aforementioned.

This is due to the material's proprietary blend of nylon, elastane, and polyester. The resulting blend produces an outer-surface that's textured for breathability and that accelerates moisture transfer away from the skin. And by keeping your skin cool and dry, you'll experience both irritation free pedaling and running. Izumi also added extra ventilation in the form of it Direct-Vent side panels. Essentially, this material provides a superior airflow through the shorts, while also ensuring structural stability that's free from pinching.

The fabric and structure of these shorts also provide a lightly compressive fit that maximizes muscle efficiency. And, in addition to this, the shorts' multi-panel design allows you to spin without constriction, maintain a consistent output of power.

For further comfort, Izumi also included its TRI quick-dry chamois. This insert is constructed with variable density padding that's contoured for an anatomically correct fit. And while this chamois provides the necessary support for the cycling leg, it's so bulky that it'll interfere with either the run or swim legs. The insert, as touted by its name, is also quick drying for comfort post T1.

The Pearl Izumi Elite In-R-Cool Tri Shorts are available in five sizes from Small to XX-Large and in the colors Black, Black/white, and Black/electric blue.

So far so good!

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Height: 5' 11"
    Weight: 165 lbs
    Size Purchased: Medium

First off, I'm an avid road bike rider and I'm very familiar with PI's bibshorts. I wear side M in their bibs so that's what I bought in these tri shorts. I'm 5'11" with a 32-33 waist. Initial thoughts were that they were going to be way to small when I opened the bag but they fit perfectly. A little snug on the legs but they stay in place. It's below freezing here, so tried running with them with sweatpants over top of them for warmth. The shorts are very supportive and feel great running. No chafing or bunching. Then I used them on my bike trainer and again, very supportive. I've been off the bike for a while so I don't know if it's just my butt being out of shape and not used to the saddle or if it's the thinner padding but I did notice a little discomfort after about 30 minutes of riding. I'm trying to get into shape for a local sprint triathlon and I hope these will do the trick on race day.

Just as a head's up, these shorts come in a regular and long length version. The regular has a 8" inseam and the long has a 10" inseam. They feel a little short compared to my PI bibshorts and should have went with the longer version, but I'm sure I will get used to them.

Too tight in the thigh

  • Familiarity: I returned this product before using it

These are beautiful bike shorts and I wish I could enjoy the pair I ordered. However, I sent then back because the leg bands, the bands that go around the thigh, are way too tight. In fact, they would make the beginning of a good tourniquet due to the fact the bands dig into the thigh muscles thereby constricting blood flow. I purchased a large even though my waist is 33? ? 34?. If I go up to a XL the short I feel would be to large elsewhere.
