Vest is great, zipper is so-so

This vest is very lightweight and extremely comfortable to wear. Most of the time I wear it with short sleeved shirts. When zipped, it's just right for those 45-50 degree days (as long as you're not out in the chill for really long periods - but fine for car-to-store, or short walks). It's also great around the house when you want to drop the thermostat a few degrees to save a little on heating costs. My only disappointment is the main zipper. Sometimes it takes several tries to get it started, and it often sticks mid-zip (as if there was grit or something in it). It always ends up working, but not always smoothly. I'd definitely recommend the vest, and I suspect my zipper issue is not a design flaw, but rather a production glitch, which would not likely affect other buyers.
