Modern Vespa

I have 2 open face helmets that I use my goggles with but either of them have goggle strap locks on the back. Does anyone have any suggestions on how I may be able to keep the goggles from slipping off the back of the helmet? I don't want to drill any holes or alter the construction of the helmet as it would be a bad idea anyway.

products? suggestions? homemade?

Heavy duty outdoor velcro or other "lock" strips with adhesive backing. One side on the back of the helmet and the other on the goggles strap would be my recommendation.

Velcro? Adhesive onto the helmet and sewn onto the goggle strap. You can get some hella strong Velcro these days.

thank you guys! funny enough, i have velcro left over from my tucano passenger apron

Genie is correct about putting a few stitches through the goggle strap since its stretch or other adjustment might interfere with a good bond between the velcro and strap.

3M makes an awesome ultra adhesive velcro try them.

I found http://www.gogglegrip.com/ but I am not spending $14+ just to hold my goggles on my helmet... especially of its not slipping off enough for me get annoyed.
