I’ve used the vest on chilly and damp mornings. It keeps out the cold and lets me happily slice thru the morning fog. And it’s a little nothing in my pocket when the temps warm up and I take it off.
This is an excellent little vest. Perfect for early morning rides to provide a little bit of extra warmth and, more importantly, visibility. And it packs up super small once it warms up
I'm 5'11" 170lbs, with a slim-ish build, bought a size M and it was very tight across the chest. Otherwise the garment was nice, would have kept it if the size was right.
Love this vest and perfect fit.
