Lost: REI Flash 18 pack with gear

Missing: Burnt orange REI flash 18 pack with new black waist strap, inside contents are harness, lots of draws, shoes and a headlamp. I can describe all of them to the finder.

Last seen in Big Sky, MT on Friday March 15, near Red Cliffs. All signs point to it being taken from my car. Any information is helpful. $$$ Cash reward! $$$

Please help me find my gear or keep a lookout on items for sale! If you took it, I'll buy you food or whatever you really needed to steal it for, like your own gear! :)
