I don't know the year. It's been unfolded, loosely stored in a spare bedroom inside a cotton bag for at least 5 years. I could find a date of manufacture on it. Here's a link from Mountain Hardware's site: EV2 | Mountain Hardware
It may have been used only 3 times. I can only remember one night on Rainer and twice on Adams. I just set it up and it looks brand new.
