Under 'product description' the material...
Under 'product description' the material is listed as 'polyester, mesh'. From the product photos it's not apparent where the 'mesh' is. Can you tell me?
Mesh is on the sides under the arms from the pit all the way to the waist. Also not shown in the pic is a small vent across the back from pit to pit. Compared to some, this jacket is better vented as a result.
