down here in florida and in the early season in ky i just wear shorts and a camo t-shirt under my mesh bug suit. if there's a breeze haveing the mesh allows you to feel it. no i found a new shirt that helps with it also. it's and x-scent shirt. the thing is awesome. it's kinda like under armor but cheaper and it's antimicrobial. it's like a mesh but is made to breath more in the heat and keep you warm somehow in the winter also.
