The free pouch is actually made quite well. Im currently using it as a temporary bag for my new iPhone. But I guess it would be good for the sunglasses too. ;

Work well for a wipe of the lenses.

just right for someone like me that drops my sunglasses! Thank you Pacific Coast!

Very useful carry bag, keeps lens from being scratched

Perfect for keep dust off my lenses in the hard bags. Keeps my other glasses/goggles from rubbing and scratching.
