Women's PI/Red

Women's PI/Red

Precision compression, cooling that works hardest when the sun does, and a body-contouring fit that moves with you. The women's PI/Red line is a three-piece road kit built for focused summer miles: a jersey, bib shorts, and a non-bib short that all share the same fabric logic and chamois platform so the kit performs as one system.

What Is in the Kit

Jersey: ultra-compressive Italian knit that promotes circulation and holds its shape through tempo efforts and long climbs, with UPF 30, a semi-locking YKK zipper, and three rear pockets including an internal divider.

Bib Shorts: ultra-light nylon with targeted compression, Italian lightweight mesh through the back panel and bib upper for airflow, and the dual-density ELITE Levitate™ 3D chamois.

Shorts: the same fabric, compression, and chamois in a non-bib cut with 8.5 inch inseams, for riders who prefer a waist short.

Cooling Technology

The bottoms use In-R-Cool® infrared technology with coldblack, which reduces how much heat the fabric absorbs from direct sunlight while adding UV protection. The jersey uses In-R-Cool® with HeiQ Smart Temp for responsive cooling as body heat rises, plus GoFresh™ anti-odor treatment. BioViz™ reflective elements carry visibility to 100 meters.

Fit and Chamois

PI/Red runs compressive and body-contouring, tuned to stabilize muscles and reduce fatigue rather than restrict. Both bottoms use a no-inseam construction to eliminate friction, with raw-edge leg bands and silicone grippers that stay put without pinching. The bib also uses a droptail upper, which makes mid-ride stops far easier. Start with the Size & Fit Guide, then read the Chamois Guide and Shorts & Bibs Guide to choose between the short and the bib.

Frequently Asked Questions

Find answers to common questions about PEARL iZUMi products.

  • PI/Red is a three-piece women's road kit built for hot, focused miles: a Jersey, Bib Shorts, and a non-bib Short. All three use precision compression, In-R-Cool® cooling, and BioViz reflectivity to 100 meters, and they are designed to work together as a matched system. See the full line in the PI/Red Collection.

  • PI/Red uses ultra-light nylon bottoms with In-R-Cool® infrared and coldblack to limit heat absorption from sunlight, paired with the dual-density ELITE Levitate 3D chamois. Pi PRO/BLACK sits above it: lighter Italian stretch-woven fabrics, the triple-density PRO Levitate 3D chamois, sweat-activated In-R-Cool®, and a more aggressive race fit. PI/Red also offers a non-bib short, which Pi PRO/BLACK does not. Compare with Women's Pi PRO/BLACK.

  • Both use the same ultra-light nylon, the same targeted compression, and the same ELITE Levitate 3D chamois, so the choice is about the upper. Bibs remove waistband pressure and keep the chamois centered on long efforts, and add Italian mesh through the back panel for airflow. The waist short is simpler for quick changes and shorter rides. Our Shorts & Bibs Guide walks through the trade-offs.

  • The dual-density ELITE Levitate 3D chamois, which minimizes skin abrasion and sit-bone discomfort while keeping enough stretch and breathability for high-intensity efforts. Both bottoms pair it with a no-inseam construction to remove a common friction point. The Chamois Guide explains how chamois density affects comfort.

  • On the PI/Red bottoms, In-R-Cool® infrared technology with coldblack reduces how much heat the fabric absorbs from direct sunlight and adds UV protection. That matters most on exposed summer rides, where dark fabric would otherwise build heat. The PI/Red Jersey takes a different approach, using In-R-Cool® with HeiQ Smart Temp to ramp cooling as body heat rises.

  • Close and body-contouring. The jersey is ultra-compressive with a low-profile collar and shortened torso for a sleek feel in the drops, and the bottoms use targeted compression to stabilize muscles over long efforts. Raw-edge leg bands with silicone grippers hold position without pinching. If you are between sizes or want a roomier cut, check the Size & Fit Guide.

  • Yes, that is what it was built for. The bottoms limit solar heat gain through In-R-Cool® infrared with coldblack, the jersey adds responsive cooling and GoFresh anti-odor treatment, and Italian mesh on the bib upper and back panel keeps air moving. For a full seasonal approach see the Hot Weather Guide.
