I can see the vision but I don't think this shirt is for me. As a person who jogs and/or take 4-5 mile walks daily, I didnt find this top to be very helpful. i understand its a shirt/jacket but I didnt feel like it suit me and my needs. I got this shirt in a medium and it was very true to size and since I'm busty it was very snugged around the bust area which made me feel a little constricted while i jogged. I would recommend going up a size if you have a large chest area. The material is nice, kinda like a windbreaker, and does a good job keeping you warm and dry or cooling you down. It does have a slit in the back to help heat release and that was a nice/thoughtful add on. It has pockets at the chest area, which I am not a fan of. If this is suppose to be a shirt/jacket, I would prefer pockets at the stomach/waist area, instead of the chest. It wasn't comfortable holding things in those pockets.
I wish I had something more positive to say but I just don't understand this Shirt/Jacket combo.
