Hip bag for goggle replacement lense?

[runharjar]

Hi, I’ve got the Flight Deck L goggles for skiing, and I’m looking for tips on how to bring an extra lens to the slopes. Here (in Norway) the conditions (and light) can change quite rapidly, so I figured that it’s practical to have two lenses at hand – say start the day with my Sage Gold and change to the Iced if it starts snowing/getting foggy. I was thinking trying out a small hip bag with the extra lens underneath my jacket. Have anyone tried it? Are there any Oakley bags for that purpose? Cheers.
