Outlet for ski clothing?

The closest outlet mall is in Silverthorne, which you can easily hit if you're flying into Denver. Otherwise, you can find inexpensive things at Sports Authority on the other side of I-70 or maybe snag a deal in Vail Village or Lionshead. 

Many places have some left over clothing from last year, it helps to be small or large size, in Vail itself.   Those deals will disappear in the next 10 to 15 days.  If you can hop east over Vail Pass to Frisco (Colorado)you can find shops there with 2013-14 stuff, try Mountain Sports Outlet in Silverthorne and Outlets At Silverthorne as well.
