Patagonia Men's Stretch Metabolic Jacket

This is an excellent jacket. I also have a Gore-Tex XCR jacket, but this one is just IT.

A very lightweight jacket with 3-layer reinforcements at the right places. On the shoulders so you can carry your bagpack without damaging the jacket. More than enough ventilation openings and taped zippers are the finishing touch. It has a very good fit around your body with elastic pieces. Never leave home without it, no matter what you'll be doing...
