Im sure there comes a point when a vest is less effective than a jacket. I wonder if in ‘cool’ temperatures it might be effective. I’m thinking in the like 55°-60° F range for me personally.
That's the forecast for our Sunday round. I have to have one of these stupid things still hanging around somewhere. I will dig it out and wear it just to prove to myself that it serves no useful purpose. I will take a picture and update my av accordingly. lol
edit: If I shoot a 65 or something I will never forgive Jman for making this thread and putting me in the position to believe it had something to do with the power of the vest.
