I have been using the Ursack White in Inyo National Forest for over ten years, with no bears able to get into it. Ursack.com. Legal in most areas, but not legal yet in Seki or Yosemite. The Ursack website has a map showing approved areas.
The Ursack MUST be used according to the manufacturer's instructions: the tie knot must be secured correctly. Only the "White" models are bear resistant.
The permits require "bear resistant" containers. No containers are absolutely bear proof if not used properly.
Don't store fresh fruit in them, because the bears tend to jump up and down on the Ursack trying to break in...
