I lost a new topeak panoram computer when it catulapted into the canal after coming down a bridge.
Lost my ACE!! snowboard mitts… during a dryslope session somehow..
Lost a Kool Tool (snowboard tool) whilst snowboarding in the UK in last years snow.
Really fustrating…I make a rule of never leaving anything on the car roof post ride and always checking before I leave anywhere, which helps.
For you Oakleys guys .. get a neck strap for your shades. Ski shops should sell suitable ones.
