Male, 6’1, ~185, athletic build. Bought the Large. Fits great, not to large in the chest. Has inner pockets and front outter. Zipper is very clean / smooth. Jacket is comfortable and made very well. I originally ordered the Medium, and was a bit snug.
If you are to make a Gen 5, would def make the jacket just a tad longer. I’m usually a Patagonia jacket wearer, this is one is great and part of the rotation.
