I've been using the belt running in autumn / winter. Since I am much in the forest and on unlit country roads, I was for some time in search of more reflecting surface as they offer skiing trousers and jackets. And I am independent of the reflection of the clothes. The setting is slightly out of hand and the comfort is good. Why good? Because the straps on the shoulders rub the neck, so you should wear outer garments with collars. I would buy the strap definitely be back.
