I was looking for a wind breaker jacket to keep me comfortable in the cooler weather this fit the bill. I have been out riding in the 40's high 30's with a thermal shirt under the jacket keeping me comfortable. This is my go to jacket when it gets cool. And the screaming yellow is a nice choice can't be missed I have also used on walks.
These are light, packable, removable sleeves, low cost.. Perfect. Pay attention to size. I'm 5'11 and 170 lb. I've always worn a medium in pearl izumi jackets. Suddenly, a medium doesn't fit. I bought one of these for my son who always wore a large, and suddenly he needs an XL. Our height and weight didn't change.
This quickly became my favorite piece in the morning. Its all I need to get rolling on top of a LS jersey. Halfway through the ride the arms come off but the vest remains. Super lightweight and easy to wear.
