It definitely blocks the wind. I wear this over a couple of layers when it's pretty chilly outside.Arms are long enough for me, and it fits well. It's nylon, so you can't wear it snug. Expect a little wind drag.It has a pocket on the back with double-sided zippers, and elastic straps. It folds up into itself, and you can strap it to your bike.The problem I have with this is that it does not breathe at all. No matter how cold it is, I sweat inside of this, and it condenses. No vents, perforations, etc. It's very close to wearing a plastic bag.
