It's not what it looks like, but what's inside is amazing!
Chest and spine are protected by plastic.
Urethane pads are also inserted in the armpits for full coverage of the upper body.
Simply slip it on under your existing protection (shoulder, elbow, spine) jacket and it will protect your entire upper body.
In addition, you can easily wear it over your shirt in the summer when it is painful to wear a jacket, and you can protect your vital parts.
