Summit Aero Mesh Jersey with 37.5® Technology

The Summit Aero Mesh is not just light and breathable...

37.5 Technology

We've combined the breathable mesh fabric of the Summit Aero Mesh with 37.5® Technology, known for its ability to move heat and moisture away from the body, to keep you cooler over long distances.

HOW DOES IT WORK? 37.5® Technology uses active Cocona particles which respond to body heat to accelerate vapor movement and significantly increase drying rates. This means the hotter the user gets, the stronger the driving force to remove moisture becomes—and the dryer your skin stays. This regulates core body temperature and results in up to a 25% increase in athletic performance (results based on an independent University of Colorado study).

It’s a bit like magic, and if you’re used to a typical polyester jersey, you’ll truly appreciate the breathability and feel of the Summit Climber's. Learn more at
