I use this for biking and hiking, I have 2 jackets. It has nice material and good ventilation when working out . Good for mild cold weather.
Color is very bright, can be seen from far. Fabric is not too heavy or thin, works great for bike riding.
I like the jacket overall- it is a nice, lightweight, and doesn't flap in the wind. However, it is not waterproof. I rode for about an hour in a light to medium rain on a return trip and my clothes underneath were damp.
