I may have missed this in all the searches that I did... Im trying to figure out which coat to wear on the TAT that Im leaving for in a few days. I go back and forth between my mesh Vanson with protection or my full synthetic black First Gear that is vented. I would wear my gore tex rain coat over the mesh in rain or not bring it at all if I had the First gear. It will be really hot in the full coat at some points compared to the mesh... But if it is cold??? Because this trip covers so much ground i am confounded... What do you travelers have to say??
