Anybody know if you can get covers to go over the arms of shades?

I have a favorite pair but they slip about when moving my head around to much, want something to stop this, preferably covers or something, rather than a strap round the back of my head.

Thanx for the help.

 

You can get the foam strap that slides on over the earpiece and arm, then just cut the back off the strap.

The other option I used once was to get some small gage heat shrink tubing for cables...it had a grippy rubber surface and you can make it any size or color you like. See example here... http://cableorganizer.com/heat-shrink/
