YOUR GUIDE TO HOT WEATHER DRESSING.

When things start to heat up, reach for your lightest layers. If desired, a mesh or merino base layer can help keep you dry. Select a lightweight jersey; every PEARL iZUMi summerweight jersey uses one of our unique cooling systems. Lastly, select a high-quality pair of shorts or bibs and lightweight socks. Ultimate coolness unlocked.

TECHNICAL INNOVATION

IT'S NO SWEAT.

Our transfer fabrics are optimized for warm and hot conditions and made with technical fibers that move perspiration away from your body. This evaporation process works faster than traditional sweat-wicking fabrics, helping you maintain stasis as you ride.

BEAT THE HEAT

STAY COOL WITH IN-R-COOL®.

Our most powerful cooling apparel uses In-R-Cool® technology, which activates in two ways. An infrared-activated layer reflects the sun's rays to lower fabric temperatures, while sweat activation initiates a cooling process.

ENHANCED FABRICS TO HELP YOU CHILL.

Our fabrics provide a second-skin feel, with optimal ventilation and moisture removal so you stay comfortable and dry. Feel the barely-there difference.

Hot Weather Cycling FAQ

What should I wear cycling in hot weather?

Reach for your lightest layers: a summerweight jersey, shorts or bibs, and lightweight socks. A mesh or Merino base layer helps rather than hurts, because it moves sweat off your skin where it can evaporate. Add sun coverage on your arms and head if you are out through the middle of the day.

Does a base layer make you hotter?

No, and this is the most common misconception about hot-weather kit. A lightweight base layer pulls sweat off your skin and spreads it across a wider surface to evaporate, which cools you more effectively than bare skin trapped under a jersey.

How does In-R-Cool® work?

In-R-Cool® works in two ways. An infrared-reflective layer bounces the sun's rays to lower the fabric's temperature, and sweat activation starts an evaporative cooling process as air moves across the garment. The result is a lower body temperature at the same effort.

Do light or dark colors keep you cooler?

Light colors reflect more solar radiation, so they are the safer choice in direct sun. The difference is smaller on a moving bike than standing still, because airflow does most of the cooling work, and In-R-Cool® reduces heat absorption regardless of color.

KEEP YOUR COOL.

Lighten up, then go ride.
