Alien Technology! I've owned this THING for six years. I've bicycle commuted with it and a merino base-layer in the winter while living in Sasebo, Japan, and remained completely comfortable. Also have traveled in and about Seattle and New York State during the colder months.
I remember recently walking around near Times Square in February (after returning on a flight from TX) with others completely bundled and myself being quite comfortable with this, and a OR Peruvian Hat on. I can only wish that they made puffy mitts too!
An improvement that I'd love to see is stowage in a sewn on pocket compartment, instead of a separate stuff sack (that rarely gets used or brought with me).
