I bought this to wear while on an elk hunt in Colorado. I wore it every single day, and even some nights. One night the temps when we woke up read 9 degrees F according to the truck dash display. We had a wood stove but it only went so far in a canvas wall tent. My vest saw 10 days and some nights of continuous use. I love the vest. I pack it with me in my laptop bag for work when I travel. You can't ever tell if it will be warm or cold on the plane, this vest is the perfect garment for trying to hit that sweet spot so I can sleep on the plane in comfort. With Eddie Bauer you know you still look good too. For work sometimes I have too work in walk-in cooler environments for a couple hours at a time. This vest helps make that a little more manageable too, and again, maintains a professional look.
