Vent fabric is a summer weight vented fabric for maximum breathability and cooling in hot summer conditions.

Waffle texture on a cycling garment causes turbulence in the thin layer of air closest to the dimples. This layer of turbulent air is able to follow the contours of the garment much longer creating a smaller wake and and lower drag. (This is also known as the golf ball effect because it's why golf balls have dimples).

You might not even notice at first, but the extra effort we put into the finishing details of our garments, such as high load areas like the pockets, means they'll last you twice as long.
