The hard case that came with my Cutlines was excellent and sufficient until I purchased a few additional lenses. The Patrol Pack is the perfect carrying/storage solution to ensure your glasses, spare lenses, cleaning cloth, etc. stays safe and secure. Easy to throw into a bag you'll never be digging around or wondering where you left your glasses and spare lenses.

If you have multiple lenses, this is a great accessory to have. Its not a hard shell but does the job and handy with all replacements lenses in single case.

Excellent case holds extra lenses glasses perfectly
I use it for my Rydon glasses and extra lenses
