Now that the warm weather is here ( in the US) I found a couple of very light weight cotton jackets for the cool nights that pop up occasionally. While they look heavy they are really thin cotton fabric that’s very comfortable to wear. They are made by Rothco and patterned after the US Army M-65 Field Jacket. They look like a winter jacket but are perfect for cool evenings. They have a draw string hood rolled up in the collar for rainy weather. I highly recommend one if you are into the fatigue jacket look.
