I needed to get better support for my Goggle RE. Not enough rear head support.
Bought the Giro Roc Loc 5 retention system. About $10. Zip tie to helmet. Perfect support.
Got mine from Excel Sports, but available multiple sites.
see this thread for how simple elastic bands and a GoPro scuba camera belt allow you to take all the weight off you neck with the Goggles: They work well.
