Input:
These shirts are great.  They are cut loose enough that the vents really do let air in and reduce sweating.  They keep me fairly cool and keep the sun out, too.  I have three or four and I might get a couple more if I could find a few in the colors which always seem to be out of stock.
p.s. They are warm enough to wear in above freezing weather too.. justust wear a jacket to keep the wind out.
