Ive used the vest for 3 morning commutes. Temp high 50s- low 60s. It qas perfect. I'm 5'11" 170lbs with a bit of beer/wine gut. Bought a large. Fits Perfect and looks great.
Only used the vest a couple times so far but seems to be well-made. Pockets are a great addition in the back and the colorway is bright on road. Only minor quibble is the armpit holes are oddly shaped and I don't particularly love that it looks like a pair of parentheses (from the front) but that's purely aesthetic not functionally different. Fits well too - 6'1 180 and it's a large on me.
Fits perfect, looks even better. All my friends are beyond jealous!
