“While it feels very lightweight it is very warm & windproof. I wore it on a cool 60-degree morning last week and it knocked off the chill. When it warmed up after riding a couple of hours I took it off rolling it up like a scarf and tied it around my waist. I ride a Giant Liv carbon fiber bicycle and only carry a small handlebar bag so I don't have a lot of storage nor do I want to. The less weight I carry on my bike the faster and easier the ride especially on hills.”
